- Summary: Manufacturer overview, 25+ year history (founded 1997), and facilities

Once the imager is chosen, the process for selecting an M12 lens (also called S mount lens) does not differ from that of selecting other CMOS lenses and consists of the following steps:

- Determine the desired field of view (in angles if the object is at infinity, and in actual sizes if the object is at a finite distance).
- Calculate the required focal length of the lens, and the image circle size. We have created a wizard to perform this calculation.
- Choose an appropriate lens f/# based on similar lighting environment and depth of field requirement. We have created a wizard to calculate the depth of field.
- Determine the appropriate lens performance requirements such as modulation transfer function (MTF), chromatic aberration, distortion, and relative illumination.
- Specify the mechanical size constraint and reliability requirements.

#### Imager format and resolution

The starting point is the format size which is linked to the effective area of the imager. The format size definition comes from pre-electronic imaging era. It does not directly represent the diagonal size of the effective area. Commonly seen imager formats and their actual physical sizes are listed below. The imager resolution is the number of effective pixels in the horizontal and vertical directions. The total number of pixels is often used to represent the nominal resolution of an imager.

- The max. image circle of a lens is the area over which the lens will provide an acceptable performance. For standard applications only lenses with image circle greater than the imager diagonal size should be selected (see below graphic). If the image circle is smaller than the imager diagonal black or darker corners will result. However, for ultra wide-angle systems, it is common to have the fisheye lens image circle smaller than the diagonal of the imager. If the entire image circle is contained within the effective area of the imager, a circular image is formed. If the imager circle is less than the horizontal width of the imager but greater than the vertical height, a horizontal frame is formed.

#### Effective focal length and field of view

Once lens image circle is determined, the next step is to determine the appropriate lens focal length (EFL) required to achieve the desired field of view. The lens EFL is an intrinsic property of the lens independent of the imager used. The max. lens field of view (FOV) is specified for the image circle size. However, the field of view of CCD/CMOS camera depends on both the lens EFL and the size of the imager area. If the lens distortion is small (known as rectilinear lenses), the following formula can be used to calculated the camera FOV:

- where x represents the width or height or diagonal size of the imager, and f is the lens EFL. We have created an online wizard to perform various FOV/EFL calculation. When there is a significant amount of distortion in the lens such as in the case of very wide-angle lenses and fisheye lenses, the calculation of the FOV is much more involved. We have developed a new concept called “rectilinearity” to characterize the distortion properties of ultra wide-angle and fisheye lenses. When used in conjunction with the effective focal length, the field of view and distortion property of a lens can be fully analyzed without having to know the detailed lens prescription.
#### Relative aperture or f/#

- The f/# of the lens has two impacts: (1) the amount of light that the lens collects, and (2) the depth of field (DOF). For low-light environment, it is often necessary to choose a lens with low f/#. However, the depth of field of a low f/# lens is limited. Low f/# lenses are also more complex and thus more expensive to produce. Therefore, the optimal f/# selection is based on the tradeoffs between various performance parameters and lens cost. It is usually possible to increase the f/#(stopping down the aperture) of an existing lens design without a detrimental impact on the image quality. However, lowering the f/# (increasing the aperture size) is usually not possible without causing a significant compromise in the image quality/relative illumination.
#### Nyquist frequency and image quality

- Aa digital imaging system the pixel array of the imager samples the continuous spatial image formed by the optical system. Nyquist Frequency (NF) represents the highest spatial frequency that the imager is capable of detecting. The NF depends on the pixel pitch, color filter array (CFA) design, and the processing algorithms of the entire imaging processing chain. Lens image quality can be the gating factor in the overall image quality of a digital imaging system. To realize the full resolution of the imager the lens resolution should be greater than the NF. The lens should provide sufficient spatial detail to the imager sensor if each pixel of the imager is to be fully utilized. Lens image quality is characterized by its modulation transfer function (MTF). The MTF of a lens varies with spatial frequency as well as angle of the incidence. A good lens should have MTF >40% up to the sensor Nyquist frequency. It should also provide a consistent MTF across the entire field of view of the lens.
#### Relative illumination and telecentricity

- The light collection ability of all lenses falls off with an increasing field of view. Relative illumination of a lens is defined as the ratio of light intensity at the maximum angle of view to that on-axis. For electronic imager sensors (CCD and CMOS), the off-axis brightness is further reduced by the collection efficiency of the imager pixel structure. Many modern imagers use a micro-lens over each pixel to increase the fill factor. The micro-lens will limit the field of view of the pixel. To be maximally compatible with the micro-lens field of view, the rays emerging from the lens must be within the acceptance angle of the micro-lens for all off-axis rays. This typically require that the primary lens be telecentric in imaging spacing. Non-telecentric lenses can also cause color and resolution cross-talk between adjacent pixels. This will further impair the off-axis performance of the imaging system.

Download a white paper on chief ray angle. #### Chromatic aberrations

- Optical materials have different indices of refraction at different wavelengths, known as dispersion. The material dispersion causes light at different wavelengths to focus at different focal plane (axial color) and different image height (lateral color). Lateral color can be seen as color fringes at high contrast edges of off-axis objects. Chromatic aberrations can be minimized or eliminated by using a combination of lens elements with different dispersion properties. Download a whitepaper on lateral color.
#### Distortion

- Lens optical distortion describes how the image is deformed with respect to the object. Distortion (%) is defined as follows:
where

*ychief*is the image height for an off-axis chief ray, and*yref*is a reference image height for the off-axis field angle. For normal field of view lenses, the reference image height is

defined as:where f is the effective focal length and θ is the field angle. The resulting distortion is known as “rectilinear” or “f-tan” distortion. Most standard photographic lenses have low rectilinear distortion. For wide-angle and fisheye lenses, the reference image height is typically chosen as the product of focal length and field angle (in radians):

The resulting distortion is known as “f-theta” distortion. Please note that a zero f-theta distortion lens can still look very “distorted” visually. It is possible to “tailor” distortion in such a way that the off-axis resolution is enhanced from the standard “f-theta” type. Sunex has developed unique designs and manufacturing know-how to provide wide-angle lenses with tailored

distortion. We also provide Photoshop-compatible plug-in to “de-warp” images taken with tailored distortion lenses.

Visual impact of various lens distortion (value is calculated for the

corners)#### Depth of field or focus

- The depth of field (DOF) of a lens is determined by several factors: the relative aperture or f/#, the lens EFL, the maximum acceptable blur, and the lens MTF. Generally speaking, higher f/# lenses will have more DOF. Shorter EFL lenses will also have more DOF. We provide a wizard to calculate the depth of field for a given lens. If the MTF of the lens is higher, the perceived DOF will also be greater. Because the maximum allowed blur size is somewhat subjective and application dependent, it is strongly recommended that experimental verification of the DOF to be performed.
#### Flare, scattering and ghost images

- Flare is caused by improper engineering of the lens internal structure such that light rays outside the field of view is “leaked” into the normal field of view. Scattering is caused by the surface roughness of the lens element that causes an overall reduction in the contrast of the image. Ghost images are formed when light rays are bounced multiple times inside lens/sensor structure causing additional “weak” images to be formed near the primary image. These are all optical “noises” which can cause degradation to the overall image quality. Careful consideration must be

taken in the design and manufacturing processes to minimize the undesired optical noises. #### IR cut-off filter

- IR cut-off filtering in the optical chain is required to form accurate color images. IR cut-off filtering can be accomplished by inserting an IR-cut off filter in the lens system. Another option is to apply the IR cut-off coating onto the lens elements directly.
#### Optical low-pass filter (OLPF)

- The image formed by a lens is continuous in space. This image is “sampled” by a CCD/CMOS sensor with a sampling frequency equal to the inverse of the 2x pixel pitch. If the image contains objects at spatial frequencies higher than the sampling frequency of the imager, the resulting image will have aliasing artifacts. This phenomenon is often observed as colorful fringes (Moire fringes) on the final images. In high quality imaging systems, optical low-pass filters (OLPF) can be used to eliminate the Moire fringes. OLPF cuts off the lens MTF above the sampling frequency of the imagers resulting an overall MTF that approximates a step function (in spatial domain). Download an application note on OLPF.
An OLPF is made of 1 to 3 layers of optical birefringent materials such as quartz. Each birefringent layer splits a light ray by polarization as shown below:

## What is an M12 lens used for?
M12 lenses, also called S-mount lenses, are compact, low-cost lenses
widely used in robotics, drones, automotive cameras, and embedded vision
systems due to their small size and reliable optical performance.
## Which M12 lenses are best for robotics / drones / industrial?
For robotics applications, durable automotive grade M12 lenses are recommended, as they provide high CRA
compatibility and stable performance in industrial environments.
## What are M12 (S-mount) lens size or dimensions ?
A M12 lens uses a metric M12×0.5 threaded barrel that screws into a board-level
lens holder also known as M12 lens mount. It’s compact, lightweight, and
cost-effective comparing to larger lenses. They are commonly used
in embedded vision cameras (machine vision, robotics, surveillance,
conferencing, and industrial cameras). M12 lens is also known as s-mount lens in some industries.
The sizes of a M12 lens can be anywhere from a few millimeters to
several centimeters depending on the design and use case.
## Are M12 lenses good for harsh environment ?
Sunex designs and manufactures M12 lenses in our own facilities certified
for automotive grade lens productions. Our products are "Engineered
for Reliability" from design to manufacturing to lower the total cost of
ownership. Some
online distributors or middleman companies source their products from
low-cost Chinese factories without guarantted availability of the
products in the future.
## Which sensor sizes do M12 lenses support?
These lenses can cover formats from sub-1/5″ up to ~1″, depending on the optical design. Always check each product’s specified image circle or supported sensor format.
For larger sensor formats, we recommend a CS mount or a custom M mount
for higher optical performance.
## How do I choose focal length and field of view (FOV)?
Match FOV to your working distance and sensor size. As a rule: shorter focal length ⇒ wider FOV; longer focal length ⇒ narrower FOV. Use an
FOV calculator or the product FOV charts to
pick a lens, then verify with an actual sample.
## What resolution can M12 lenses support?
Resolution depends on the lens MTF and your pixel size. Our M12 lenses can support multi-megapixel
sensors up to 20MP+ pixels.
## What’s the difference between IR-cut and NIR versions?
IR-cut versions include a filter or multi-layer coating
on the lens element(s) that blocks near-infrared to preserve accurate color in visible light. NIR versions transmit near-infrared for illumination or monochrome sensitivity; colors will not be accurate but low-light/NIR performance improves.
There are also designs optimized for visible and NIR wavelength bands.
Those lenses are known as
RGBIR lenses useful for automotive interior cameras.
## How does lens distortion and/or relative illumination impact
what I see ?
Lens distortion and relative illumination are unavoidable in all lenses.
During design we control those values to acceptable levels for intended
use cases. Please check out our online
Distortion Simulator with relative illumination (or
MTF Simulator).
We offer Tailored Distortion or
FOVEA distortion lenses to maximize the
distribution of the pixels across the FOV for your use case.
## What is CRA and why does it matter?
CRA (chief ray angle) is the angle at which light reaches the sensor corners. Some sensors have microlenses that require certain CRA ranges. Match the lens CRA profile to the sensor to avoid corner shading or color shifts.
This article by our engineers discusses the CRA impact on lens
performance.
## How do M12 lenses compare with C-mount or CS-mount lenses?
M12 lenses are smaller, lighter, and screw directly into a holder—great
for compact, cost-sensitive systems. C/CS lenses use a flange (C:
17.526 mm, CS: 12.5 mm back focus) and are larger but offer larger
sensor format coverage and provide more adjustment options such as
aperture, zoom and focus.
## Do you offer CAD models, filters, and custom options?

distortion is un-avoidable for ultra wide-angle and fisheye lenses.
Dewarper Mini is a plug-in (compatible with 32-bit version of Adobe Photoshop,
Photoshop Elements and Corel Paintshop Pro only, not compatible with 64-bit
version) for optimizing distortion taken with Sunex miniature ultra wide-angle
and fisheye lenses. It remaps the pixels such that the processed image is
optimized for the intended application. This software is based on a new
proprietary mathematical model developed by Sunex for real-world lenses.
Unlike other distortion correction software, Dewarper Mini does not assume that
the lenses have either equidistant or equi-solid angle mapping. All
distortion types can be modeled including our
Tailored
Distortion™ lenses. Software licensing is available for OEM
applications.

## FOVEA™ distortion lenses

- Source: https://www.optics-online.com/dsl_fovea.asp
- Summary: Tailored distortion for optimal pixel distribution

The term “Fovea Distortion” is
derived from the fovea centralis which is located in the retina’s center
and is responsible for high-acuity human vision. Sunex lenses with
Fovea distortion map this type of behavior and “exaggerate” the central
details while trading off the off-axis details. Technically speaking,
this results in a higher number of pixels per degree in the center,
allowing machine vision algorithms to benefit from a higher resolution
in the center field compared to standard f-theta distortion lenses.
The following graph shows the typical angular resolution vs. field angle
curve for such a lens:

- Summary: Industrial and embedded vision applications

##
## Finite Imaging
Our low-profile compact lenses are designed to
provide high image quality with low distortion when the object distance
is greater than about 10 times the focal length, or for on-axis imaging.
They are applicable for finite object imaging applications such as
face/object recognition, barcode readers, document imaging, machine
vision, and biometric security.
We provide two online wizards to assist you to choose the right
lens:
- Imaging optics solver: Solves for
the effective focal length (EFL) based on object and image size
constraints. A good starting point for finite conjugate applications
such as barcode scanning, etc.
- Field of view or EFL calculator:
Calculates FOV (in degree) of a lens on a given imager if the EFL is
known, and vice vesa. This wizard factors into the geometric
distortion of the lens. Therefore, it is applicable to all
lenses from telephoto to fisheye types.
- List of off-the-shelf finite imaging
lenses
## Robotics Vision
Many of Sunex standard wide-angle and fisheye
lenses are suitable for robotics vision applications. For 3D
applications we offer Boresight Stabilization – a proprietary technology
eliminating lateral shift (Boresight) of the lens elements due to shock
or vibration. This is especially critical in 3D imaging, where a shift
of just a few pixels is often unacceptable.
## Inspection
Sunex wide-angle and fisheye lenses are becoming
increasingly popular in a variety of inspection application, such as
boroscopes or pipe inspection. Several factors make Sunex lenses
ideal for this type of application. The low profile and small physical
sizes of our lenses, combined with small sensor formats for which the
lenses were designed, allow for very compact camera packaging. Moreover,
our ability to customize provides you with a variety options to meet
your unique requirements.
#### Customization Capabilities Include:
-
IP rated sealing
-
IR coatings with IR band-pass for Day/Night
imaging (IRC40)
-
Hydro-phobic/phillic coatings
-
Relative aperture (F/#) modifications (calculate
depth of field)
-
Mechanical barrel redesign

## Immersive / VR imaging

- Source: https://www.optics-online.com/Solutions/CompactMobile.asp

Lenses for consumer products are designed to achieve
optical resolution suitable for multi-megapixel sensors
including 4K HDR imagers. Many of these lenses are
designed to achieve up to 170° field of view and are
commonly used as sports action cameras and compact
camcorders.
These lenses are made with a combination of high-precision, spherical
glass as well as injection-molded, aspheric plastic elements. This
enables wide-angle lens designs with our exclusive
Tailored Distortion®
technology, minimizing optical distortion. These designs use proprietary
manufacturing processes to minimize unwanted lens flare and ghosting to
provide best-in-class image quality in cameras using HDR imager sensors.

## IR cut-off filters

- Source: https://www.optics-online.com/irc.asp

Infrared
(IR) cut-off filters are used with color CCD or CMOS imagers to produce accurate
color images. An IR cut-off filter blocks the transmission of the infrared
while passing the visible. This can be done with two optical techniques:
absorption or reflection. Absorptive filters are made with special optical
glass that absorbs near infrared radiation. Reflection type filters are
short-pass interference filters that reflect infrared
light with high efficiency.
We offer two types of absorptive filters: IRC20 and IRC21 and two types of
reflective IR filters: IRC30 and IRC40 which is a new type of reflective filter
suitable for day/night security cameras. It allows both visible and
infrared LED light to pass through. The absorptive filters are recommended
for CCD imagers while the reflective CMOS imagers. Our standard
off-the-shelf filters are listed blow. If you need a custom filter, please
contact our support.

## Optical low-pass filters

- Source: https://www.optics-online.com/lpf.asp

In
high-quality digital maging systems, optical low-pass filters (OLPF) are
used to eliminate color Moire fringes. An OLPF cuts off the
lens MTF above the sampling frequency of the imager
resulting an overall MTF curve that approximates a step function in spatial
domain. IR cut-off function is often incorporated
into OLPF as well. See CCD/CMOS lens selection
guide for discussion of OLPF and its impact on image quality.
Download an application note on optical low-pass filters.
OLPFs are made of several cemented layers of optical quartz material. An IR
cut-off coating and anti-reflection coating are applied to the external
surfaces. If the IR cut-off filter type is absorptive, the IR glass is
inserted between the quartz layers. Custom OLPF sizes and designs are also
available.
### General Specifications:
Parameter | Value | | Default unit | mm | | Default dimensional tolerance | +/-0.2mm | | Coating
External surfaces single

## Rapid prototyping

- Source: https://www.optics-online.com/Custom/prototype.asp
- Summary: From spec to first samples

| My Account | Shopping Cart | |||||
We provide prototyping services for complete lens assemblies.
Using state of the art fabrication processes, we can produce prototypes
very quickly to verify the design before commitment to production.
Upon your approval, we will start mass production in our factories in
China. The
specifics of the prototyping process depend on the design details. For
each type of components used in the lens assembly, a different process
will be used.
## Glass optics for Lens AssembliesGlass optics (lens elements, prisms, etc.) are fabricated using jigs and fixtures including grinding and polishing laps, etc. We use interferometers to test the surface accuracy and roughness without fabricating custom test plates at this stage. Generic and general purpose fixtures are used for coating applications. Once the prototype glass elements are fabricated, we conduct extensive tests and measurements to verify the accuracy of the components. ## Plastic optics for Lens AssembliesHigh precision, low-volume tooling is fabricated first to ecomonmically and quickly verify the performance and demonstrate manufacturability of the design. Once the prototypes and design are confirmed, the low-volume tooling can be scaled up for mass production by adding additional cavities.
## Mechanical components and assemblyMechanical components typically are first produced in aluminum using state of the art CNC-machining equipment. The components are then finished matte black to minimize specular reflection. This process allows for quick validation of the lens assembly design before committing to production fixtures or tooling. Once the components are fabricated and tested, the assembly process takes place in our clean room assembly area. In many applications the aluminum mechanical components are suitable for production. However, if your application demands plastic mechanical components Sunex has the capability to provide this as well. ## Prototype testingOnce we have the prototype assemblies we conduct extensive tests to verify that they meet the agreed design requirements. Our engineers design and build fixtures that enable us to test your lens assembly on our in-house commercial test equipment. A typical set of tests will include: optical performance, mechanical dimensions, cosmetics, and other functional requirements.

## M12 lens selection guide

- Source: https://www.optics-online.com/CCDlens.asp
- Summary: Step-by-step guide for specifying engineers

Once the imager is chosen, the process for selecting an imaging lens
such as popular M12 or known as s-mount
lenses consists of the following steps:
- Determine the desired field of view (in angles if the object is
at infinity, and in actual sizes if the object is at a finite
distance).
- Calculate the required focal length of the lens, and the image
circle size. We have created a wizard to
perform this calculation.
- Choose an appropriate lens f/# based on similar lighting
environment and depth of field requirement. We have created a
wizard to calculate the depth of field.
- Determine the appropriate lens performance requirements such as
modulation transfer function (MTF),
chromatic aberration, distortion and relative illumination.
- Specify the mechanical size constraint and reliability
requirements.
Pick the right M12 (S-mount) lens for your project
- Imager format and resolution
- The starting point is the format size which is linked to the effective
area of the imager. The format size definition comes from pre-electronic
imaging era. It does not directly represent the diagonal size of the
effective area. Commonly seen imager formats and their actual physical sizes
are listed below. The imager resolution is the number of effective pixels in
the horizontal and vertical direction. The total number of pixels is often
used to represent the nominal resolution of an imager.
Imager Format | Approximate horizontal size (in mm) | Approximate vertical size (in mm) | Approximate diagonal size (in mm) | | 35mm full frame | 36 | 24 | 43.3 | | APS-C | 23.6 | 15.6 | 28.3 | | 1.5" | 18.7 | 14.0 | 23.4 | | Micro 4/3rd | 17.3 | 13 | 21.7 | | 1" | 12.8 | 9.6 | 16.0 | | 1/1.2" | 10.67 | 8 | 13.4 | | 2/3" | 8.8 | 6.6 | 12.0 | | 1/1.7" | 8.06 | 4.54 | 9.25 | | 1/2" | 6.4 | 4.8 | 8.0 | | 1/2.3" | 6.17 | 4.55 | 7.8 | | 1/2.5" | 5.7 | 4.32 | 7.2 | | 1/2.7" | 5.3 | 4 | 6.6 | | 1/3" | 4.8 | 3.6 | 6.0 | | 1/3.2" | 4.54 | 3.42 | 5.7 | | 1/4" | 3.6 | 2.7 | 4.5 | | 1/5" | 2.56 | 1.92 | 3.2 | | 1/6" | 2.16 | 1.62 | 2.7
Good article
on sensor size trade-offs
- Lens image circle vs. imager size
- The max. image circle of a lens is the area over which the lens will
provide an acceptable performance. For standard applications only
lenses with image circle greater than the imager diagonal size should be
selected (download
application note). If the image circle is smaller than the imager
diagonal black or darker corners will result. However, for ultra wide angle
systems, it is common to have the fisheye lens image circle smaller
than the diagonal of the imager. If the entire image circle is contained
within the effective area of the imager, a circular image is formed.
If the imager circle is less than the horizontal width of the imager but
greater than the vertical height, a horizontal frame is formed.
- Effective focal length and field of view
-
Once lens image circle is determined, the next step is
to determine the appropriate lens focal length (EFL) required to achieve the
desired field of view. The lens EFL is an intrinsic property of the lens
independent of the imager used. The max. lens field of view (FOV) is
specified for the image circle size. However, the field of view of
CCD/CMOS camera depends on both the lens EFL and the size of the imager
area. If the lens distortion is small (known as rectilinear lenses), the
following formula can be to calculated the camera FOV:
-
- where x represents the width or height or diagonal size of the imager,
and f is the lens EFL. We have created an
online wizard to perform various FOV/EFL calculation. When there is
significant amount of distortion in the lens such as in the case of very
wide-angle lenses and fisheye lenses, the calculation of the FOV is much
more involved. We have developed a new concept called "rectilinearity" to
characterize the distortion properties of ultra wide-angle and fisheye
lenses. When used in conjunction with the effective focal length,
the field of view and distortion property of a lens can be fully analyzed
without having to know the detailed lens prescription.
- Relative aperture or f/#
- The f/# of the lens has two impacts: (1) amount of light that the lens
collects, and (2) the depth of field (DOF). For low-light environment,
it is often necessary to choose a lens with low f/#. However the depth
of field of a low f/# lens is limited. Low f/# lenses are also more
complex and thus more expensive to produce. Therefore, the
optimal f/# selection is based on the trade-offs between various performance
parameters and lens cost. It is usually possible to increase the f/#
(stopping down the aperture) of an existing lens design without detrimental
impact on the image quality. However, lowering the f/# (increasing the
aperture size) is usually not possible without causing significant
compromise in the image quality/relative illumination.
- Nyquist frequency and image quality
- In a digital imaging system the pixel array of the imager samples the
continuous spatial image formed by the optical system. Nyquist Frequency
(NF) represents the highest spatial frequency that the imager is capable of
detecting. The NF depends on the pixel pitch, color filter array (CFA)
design and the processing algorithms of the entire imaging processing chain.
Lens image quality can be the gating factor in the overall image quality of
a digital imaging system. To realize the fully resolution of the imager the
lens resolution should be greater than the NF. The lens should provide
sufficient spatial detail to the imager sensor if each pixel of the imager
is to be fully utilized. Lens image quality is characterized by its
modulation transfer function (MTF). The MTF of a lens varies with
spatial frequency as well as angle of the incidence. A good lens should have
MTF >30% up to the sensor Nyquist frequency. It should also provide a
consistent MTF across the entire field of view of the lens.
Simulate impact of MTF to a line pair target.
- Relative illumination and telecentricity
- The light collection ability of all lenses falls off with increasing field
of view. Relative illumination of a lens is defined as the ratio of light
intensity at the maximum angle of view to that on-axis. For electronic
imager sensors (CCD and CMOS), the off-axis brightness is further
reduced by the collection efficiency of imager pixel structure. Many modern
imagers use a micro-lens over each pixel to increase the fill-factor.
The micro-lens will limit the field of view of the pixel. To be
maximally compatible with the micro-lens field of view, the rays
emerging from the lens must be within the acceptance angle of the micro-lens
for all off-axis rays. This typically require that the primary lens be
telecentric in imaging spacing. Non-telecentric lenses can also cause
color and resolution cross-talk between adjacent pixels. This will
further impair the off-axis performance of the imaging system.

- Chromatic aberrations
- Optical materials have different indices of refraction at different
wavelength, known as dispersion. The material dispersion causes light at
different wavelength to focus at different focal plane (axial color) and
different image height (lateral color). Lateral color can be seen as color
fringes at high contrast edges of off-axis objects. Chromatic aberrations
can be minimized or eliminated by using a combination of lens elements with
different dispersion properties.

- Distortion
-
Lens optical distortion describes how the image is deformed
with respect to the object. Distortion (%) is defined as follows:
where *ychief* is the image height for an
off-axis chief ray, and
*yref* is a reference
image height for the off-axis field angle. For normal field of view
lenses, the reference image height is defined as:
where f is the effective focal length and θ
is the field angle. The resulting distortion is known as "rectilinear"
or "f-tan" distortion. Most standard photographic lenses have low
rectilinear distortion. For wide-angle and fisheye lenses, the reference
image height is typically chosen as the product of focal length and field
angle (in radians):
The resulting distortion is known as "f-theta" distortion. Please
note that a zero f-theta distortion lens can still look very "distorted"
visually. It is possible to "tailor" distortion in such a way that the
off-axis resolution is enhanced from the standard "f-theta" type.
Sunex has developed unique designs and manufacturing know-hows to provide
wide-angle lenses with
tailored distortion. We
also provide Photoshop compatible plug-ins to "de-warp" images taken with
tailored distortion lenses.
Visual impact of various lens distortion (value is calculated for the
corners)
- FOVEA Distortion
- It is possible to create lens designs with tailored distortion profile
based on use case. For example in ADAS or autonomous driving cameras,
it may be desirable to see as far as possible over a narrow range of angle
centered on forward direction while still maintaining a wide field of view.
Such an imaging system is quite analogous to human vision where the best
visual acuity is achieved near the fovea region of the retina. A Fovea
Distortion lens provides more resolution on-axis than off-axis in terms of
pixels per degree in the object space. The following graph shows an example
of the angular resolution vs. field angle of such a lens:
- Relative magnification and off-axis object aspect
ratio
- When an object moves away from on-axis position, its image size and shape
can also change. This phenomenon is more pronounced for wide angle or
fisheye lenses. Relative magnification shows the change in magnification of
an object from on-axis position which is 1. Depending on the lens distortion
characteristics, there can also be a magnification difference between
tangential and sagittal directions. For example, a circular object on-axis
can become smaller and is "squeezed" in one direction when imaged at
off-axis angles. The aspect ratio shows the ratio of relative magnification
in tangential direction to that of sagittal direction. If the aspect ratio
is 1, the shape of the object is kept across the field of view. For example,
a square shaped object is still a square, not a rectangle.
- Rectilinearity
- Lens distortion is characterized by its mapping function. Well-known
discrete mapping functions or projections include:
rectilinear, stereographic, equidistant, equisolid angle and orthographic.
The concept of "rectilinearity" is introduced by Sunex as a generalized
parameter to characterize the entire mapping function set including these
known functions. Please contact us if you
are interested in getting a white paper on rectilinearity.
- Depth of field or focus
- The depth of field (DOF) of a lens is determined by several factors: the
relative aperture or f/#, the lens EFL, the maximum acceptable blur
and the lens MTF. Generally speaking, higher f/# lenses will have more
DOF. Shorter EFL lenses will also have more DOF. We provide a
wizard to calculate the depth of field for a
given lens. If the MTF of the lens is higher, the perceived DOF will also be
greater. Because the maximum allowed blur size is somewhat subjective and
application dependent, it is strongly recommended that experimental
verification of the DOF to be performed.
- Flare, scattering and ghost images
- Flare is caused by improper engineering of the lens internal structure
such that light rays outside the field of view is "leaked" into the normal
field of view. Scattering is caused by surface roughness of the lens
element that causes an overall reduction in the contrast of the image.
Ghost images are formed when light rays are bounced multiple times inside
lens/sensor structure causing additional "weak" images to be formed near the
primary image. These are all optical "noises" which can cause
degradation to the overall image quality. Careful consideration must be
taken in the design and manufacturing processes to minimize the undesired
optical noises.
- IR cut-off filter
- IR cut-off filtering in the optical chain is required to form accurate
color images. IR cut-off filtering can be accomplished by inserting an
IR-cut off filter in the lens system. Another
option is to apply the IR cut-off coating onto the lens elements directly.
- Optical low-pass filter (OLPF)
- The image formed by a lens is continuous in space. This image is
"sampled" by a CCD/CMOS sensor with a sampling frequency equal to the
inverse of the 2x pixel pitch. If the image contains objects at
spatial frequencies higher than the sampling frequency of the imager,
the resulting image will have aliasing artifacts. This phenomenon is
often observed as colorful fringes (Moire fringes) on the final images.
In high quality imaging systems, optical low-pass filters (OLPF) can
be used to eliminate the Moire fringes. OLPF cuts off the
lens MTF above the sampling frequency of the
imagers resulting an overall MTF that approximates a step function (in
spatial domain). Download
an application note on OLPF.
An OLPF is made of 1 to 3 layers of optical birefringent materials such as
quartz. Each birefringent layer splits a light ray by polarization as
shown below:
- Auto-focus (AF) lens
- Auto-focus lenses "track" the object continuously so that the image is
always in-focus regardless of the object movement. This is done by adjusting
the lens (typically using a step motor) to the imager distance based on
measured real-time object distance.
- Zoom lens
- A zoom lens is a lens that has variable effective focal length (EFL).
Since the field of view of a lens is determined by its EFL, a zoom
lens will have variable field of view. When the field of view is
decreased, a "zoom-in" effect is observed. When the field of
view of the lens is increased, a "zoom-out" effect is observed.
In "zoom-in" position, the object detail is magnified but less area of
the object is seen. In "zoom-out" position, more of the object
area is observed but detail of the object is compromised.

## M12 / S-mount / C-mount comparison

- Source: https://sunex.com/2025/06/05/m12-s-mount-c-mount-what-does-it-all-mean/
- Summary: Mount selection tradeoffs

M12, S-Mount, Board-Mount, C-Mount, and CS-Mount are all names for lens mounting formats used in cameras — and they are not interchangeable. M12 (S-Mount) lenses are the dominant standard for miniature embedded cameras in ADAS, robotics, medical, and security applications. C-Mount and CS-Mount lenses are older industrial standards still used in machine vision and laboratory environments.

This article traces the history of each format, explains the technical differences in thread, back focal length, and mounting philosophy, and gives clear guidance on which format is right for your application.

## What is the difference between M12, S-Mount, and C-Mount lenses?

If you’ve been searching for a small-camera lens, you’ve likely encountered terms like M12, S-Mount, Board-Mount, Miniature Lens, C-Mount, CS-Mount, and more. With so many names floating around, it’s easy to get confused. So, why does it seem like there are so many options? And how do you know which one is right for your project? In an effort to answer these questions, we thought we’d explore what these terms mean, where they come from, and how they relate to your lens selection.

## Why did S-Mount (M12) replace C-Mount for miniature embedded cameras?

Going back decades, the standard for interchangeable industrial lenses (as opposed to most consumer photographic cameras) was the **C-mount**. The C-Mount lens, still a staple in industrial machine vision, some security camera circles, and university labs, was one of the first solutions to standardize the lens mount format. It paved the way even before the days of CCD and early CMOS cameras.

The thread of a C-Mount is 1-32; more specifically it’s 1” in diameter with 32 TPI (threads per inch), or: M25.4 x 0.794mm. The C-mount has a standardized back focal length (BFL) of 0.69” (17.526mm), meaning that all these lenses were designed with the same flange BFL. In practice, the lens was screwed all the way down to the mount until tight and then a focusing mechanism allowed fine focus depending on the object distance. This of course made for some long TTL lenses, especially those with a long EFL. To help address the length issue, the **CS-Mount** lens format was introduced. While it uses the same thread and mounting strategy as a C-mount, it has a shorter fixed BFL of 0.4931” (12.526mm).

Although the C/CS-Mount makes for very straight-forward interchangeability, there are several drawbacks to their formats. First, the standardization of the FBFL is somewhat arbitrary in terms of optimizing optical performance and actually imposes a design constraint. Second, since the FBFL is fixed, the lens must have a secondary focus mechanism, and since the standard 32 TPI thread is not fine enough to focus 10s of microns of DOF (depth of focus), the lens must incorporate a relatively complex mechanical means of achieving fine focus. Third, the fixed FBFL alone means the TTL of the lens will be at least 12.5mm long (more for C-Mount) before even considering the physical length of the lens. Fourth, the C/CS mount is typically (but not always) integrated into the housing or chassis of the camera with the sensor-board mounted separately. This means there is no direct mechanical reference or interface between lens and sensor, which you’ll know could be a potential source of error from our AA article (Sunex Knowledge Center: What Is Active Alignment?). Lastly, but admittedly not exclusive to C/CS lenses, there is a tendency to add more features since they are interchangeable. While these features may be ideal in applications where flexibility is needed, it is less desirable for fixed, high-volume circumstances. Often, these features also come at the cost of well, cost, in addition to reliability, design and performance tradeoffs. Despite these drawbacks and the fact that C/CS-Mounts aren’t technically Board-Mounts, they still have plenty of utility. It’s important to recognize how these formats helped establish standards for lens mounting and continue to serve many applications today.

## What does board-mount mean in lens design?

“Board-Mount” or “S-Mount” lenses address the C/CS-Mount issues in a few ways. Board-mount lenses have no dependency on a fixed FBFL/BFL and no need for a separate focus mechanism. They are designed to thread into a threaded mount directly attached to the sensor PCB. The thread doubles as the focusing mechanism because it typically has a 0.5mm or 0.35mm pitch making it fine enough to focus a lens (see our article Sunex Knowledge Center: Basic Thread Considerations). It also eliminates many (but not all) sources of alignment error between lens and sensor by placing the lens directly on the sensor board. Of course, this means that the BFL, FBFL and MBFL are coupled to the focal position of the lens. This means the focal position changes slightly from camera to camera, but the differences are on the order of 10’s of microns, so it is generally not a problem.

A natural result of this board-mount approach is the proliferation of optimized, design-for-purpose lenses. “Board-Mount” is simply a general, all-encompassing term for lenses that are mounted and focused in this way. Within this broad category, M12 lenses, also referred to as S-mount, are the most common. Both terms refer to an M12x0.5mm lens, that is, a 12mm diameter lens with 0.5mm thread pitch.

In fact, “M12” has become almost synonymous with Board-Mount but in truth, while all M12’s are Board Mounts, not all Board-Mount lenses are M12 lenses. Other popular sizes of board-mount lens include M14, M10, M8, M7 and even smaller. Thread pitch tends to scale roughly with diameter and M8x0.35mm are fairly common, but in theory any size thread can be used with any diameter lens. For example, M12 “fine-focus” (M12x0.35) or even larger diameters may be specified in critical higher-megapixel applications, to gain a bit more focus control.

M12 and other Board-Mount lenses are also ideally suited to active alignment because there is no fixed BFL and therefore no secondary focus requirement. In Active Alignment, an M12 lens can have its thread removed and can be focused and fixed directly over the sensor in one step without impacting the rest of the design. For example, you could prototype with a threaded M12 lens and mount and then go straight to mass-production with a threadless version of the same lens and mount.

The other C/CS-Mount issues are addressed by M12 and other Board-Mount lenses as well. Since FBFL is not fixed, the lens design can converge on the best performance, independent of BFL. This generally leads to a much shorter overall solution. It also eliminates the need for complex focusing mechanism internal to the lens. And since such lenses tend to be built-to-purpose, gone is the need for costly and complex varifocal, aperture and locking mechanics. There are also typically commensurate gains in performance, consistency and reliability for M12 lenses compared to their C/CS counterparts because there are fewer trade-offs. While Sunex does offer C/CS lenses, we have also pioneered large-format Board-Mount lenses, such as M20x0.5 and larger. These lenses bring the old C/CS standard into the modern age by allowing them to be mounted directly over the sensor with short BFLs, with the possibility of Active Alignment. But in the world of miniature cameras, the M12 “Board-Mount” still reigns supreme, no matter what you call it.

## High-CRA vs low-CRA sensor impact on lens design

- Source: https://sunex.com/2025/06/19/high-cra-vs-low-cra-cmos-sensors-impact-on-lens-design-performance/
- Summary: Chief ray angle matching

The Chief Ray Angle (CRA) of a CMOS sensor is one of the most underappreciated variables in lens-sensor system design. A mismatch between the sensor CRA specification and the lens CRA output causes colour shading, reduced signal-to-noise ratio (SNR), vignetting, and image uniformity problems that cannot be fully corrected in software. Low-CRA sensors give optical designers significantly more freedom and typically enable better image quality at lower system cost.

This white paper examines how sensor CRA affects lens design complexity, physical dimensions, optical performance, and system cost — with practical guidance for engineers selecting sensors and lenses for embedded vision systems.

### 1.** Introduction**

**1.1. Background**

## How does sensor CRA affect lens design complexity and image quality?

High CRA sensors (CRA greater than 25 degrees) were developed to enable mobile phone cameras. The driving factor for high CRA sensors is the requirement of low z-height for the lens stack in mobile phone form factor. As shown by this paper, there are significant drawbacks of utilizing high CRA sensors for applications where a short z-height and compactness are not as important as that in a mobile phone use case.

It is advantageous to use **lower Chief Ray Angle (CRA) sensors** for high-performance imaging applications for the following benefits:

**Compatibility with Higher Performance Lens Designs:**Lower CRA sensors improve compatibility with higher performance lens designs, where chief rays arrive at the image plane close to parallel to the optical axis. By aligning the sensor’s CRA with the lens’s exit pupil position, the system can achieve more uniform illumination across the image plane and reduce distortion variation.**Improved Quantum Efficiency (QE) and Light Collection:**Each pixel on a CMOS sensor typically has a microlens array to focus incoming light onto the photodiode. When light strikes at a high angle (high CRA), a significant portion can be reflected, refracted inefficiently, or even directed into an adjacent pixel. Lowering the CRA ensures light strikes the microlenses and photodiodes more perpendicularly, allowing for more efficient light capture, increasing overall QE, especially at the edges of the sensor, and improving low-light performance.**Reduced Pixel Crosstalk:**High CRA can lead to light intended for one pixel being absorbed by an adjacent pixel, causing reduced image sharpness. A lower CRA inherently reduces this likelihood by ensuring light enters the pixel more directly, minimizing “spillover” and resulting in cleaner images with higher signal-to-noise ratio (SNR).**Improved Image Uniformity and Color Shading Correction:**High CRA can result in significant micro lens array vignetting and color shading (radial color shifts) as off-axis pixels receive less light or color filters become less effective at oblique angles. Reducing the CRA improves the inherent uniformity of illumination and color response across the sensor, simplifying post-processing and leading to a more consistent, higher-quality image.

**1.2. Problem Statement**

## What happens when the lens CRA does not match the sensor CRA?

While designers strive for optimal image quality, the choice of sensor CRA can fundamentally alter the demands placed on the accompanying optics. This paper seeks to answer an important question in optical system design: **How does the Chief Ray Angle (CRA) of a CMOS sensor influence the optical design performance and physical dimensions of a lens system designed for the same spec?**

A significant mismatch between the sensor’s CRA acceptance and the lens’s chief ray delivery can lead to critical image quality degradation, including vignetting, severe color shading, reduced overall quantum efficiency, and increased pixel crosstalk, particularly at the image periphery. While some of these artifacts can be mitigated through digital image processing, such solutions often come at the expense of computational overhead, increased noise, or compromises in real-time performance. Furthermore, in an era demanding ever-smaller and higher-performing imaging modules for applications ranging from consumer electronics to advanced industrial vision systems, understanding the relationship between CRA and physical lens dimensions is crucial for achieving optimal miniaturization, cost-effectiveness, and manufacturability without sacrificing needed optical quality. This paper aims to provide a quantitative comparison to guide more informed sensor and lens selection decisions.

**1.3. Method**

This study considers CMOS sensors across two common diagonal formats: **1-inch (approximately 16mm diagonal)** and **1/2.5-inch (approximately 7mm diagonal)**. For each format, two distinct Chief Ray Angle (CRA) requirements are examined:

- For the
**1/2.5-inch diagonal sensor (Case 1)**, cases with a high CRA of 40∘ and a low CRA of 7∘ are investigated. - For the
**1-inch diagonal sensor (Case 2)**, cases with a high CRA of 26∘ and a low CRA of 8∘ are analyzed.

For each case, we created two lens designs: a high CRA one and a low CRA one. These lens designs will be analyzed and compared based on their optical performance metrics, including **Modulation Transfer Function (MTF), distortion, relative illumination (RI), lateral color over field, and longitudinal color over aperture**. Furthermore, key physical dimensions, such as the **total track length (TTL)** and **front lens diameter**, will be compared between the two lens designs corresponding to each sensor format. To ensure a meaningful comparison, all lens designs for a given sensor format will be constrained to have the same number of lens elements, the same F-number (F/#), and to cover an identical field of view (FOV).

Since all practical designs have residual uncorrected aberrations, it is useful to review the theoretical maximum performance achievable for each CRA configuration assuming all aberrations are absent. We construct an ideal paraxial lens model in Zemax. The ideal lens model allows us to determine the upper limit of achievable MTF and RI for each case. High CRA version of each case shows that even if all aberrations can be perfectly corrected the maximum achievable performance are lower in the higher CRA versions.

**2. Comparison for Case 1: 1/2.5-inch Diagonal Sensor**

Case 1 of this study investigates the impact of CRA on optical design performance for a 1/2.5-inch diagonal CMOS sensor. The common specifications for the two lens designs considered within this case are as follows:

**Field of View (FOV):**±60∘**F-number (F/#):**2.5**Wavelength Spectrum:**435 nm to 656 nm**Chief Ray Angle (CRA) Conditions:**- High CRA: 40∘
- Low CRA: 7∘

**Number of Lens Elements:**6 (fixed for both designs in this comparison)

The primary design goals for both lenses in Case 1 include maximizing the Modulation Transfer Function (MTF) performance, with comparable optical distortion, and minimizing variation of illumination across the entire field.

- Low CRA: 8∘

**4. Results and Analysis**

## How do I choose a lens that matches my sensor’s CRA specification?

**4.1. Physical Dimensions: Total Track Length (TTL) and Maximum Lens Diameter**

The main advantage of high CRA designs can be clearly seen from physical dimension differences. **Both the total track length (TTL) and the front diameter of the lens are significantly smaller for the high CRA design compared to the low CRA design.**

The larger sizes for low CRA designs are primarily driven by the requirement for **near-telecentric imaging conditions**. For such a design, the exit pupil effectively resides at or near infinity, necessitating that chief rays strike the sensor close to perpendicularly. This condition mandates that the physical aperture stop be located approximately at the focal point of the rear lens group. To minimize pupil aberrations induced by this rear group and to maintain a close-to-linear variation of CRA with image height, the focal length of the rear lens group must be sufficiently large. These factors prevent the miniaturization of the rear lens group, contributing to a longer overall lens.

The front lens group in the low CRA design plays a crucial role in adapting the wide field of view from the object space to a smaller, more controlled angular range for the rear lens group. This function, coupled with the constraint of maintaining a small chief ray angle at the physical stop for aberration correction, results in increased complexity and length for the front lens group. Consequently, the combined requirements for the front and rear groups lead to the low CRA lens being much longer and wider than its high CRA counterpart.

Conversely, in a high CRA design, the lens group following the aperture stop (the rear lens group) has less stringent requirements for bending the chief ray of the maximum field. The physical stop can be positioned much closer to the rear lens group. Furthermore, if the overall field of view (FOV) of the lens is high and comparable to the sensor’s maximum CRA, the front lens group needs to perform less angular adaptation for the rear group, allowing for a simpler and more compact front-end structure.

**4.2. Chief Ray Angle Distribution**

The **variation of CRA versus image height is more linear in the low CRA design**, whereas the **high CRA design exhibits more significant non-linearity.** The aggressive correction of field curvature and astigmatism within the limited space of the rear lens group in high CRA designs, often employing highly aspheric elements, inherently leads to greater non-linearity in the chief ray angle as a function of image height.

**4.3. Relative Illumination (RI)**

The **relative illumination (RI) of the low CRA design rolls off much more gently than that of the high CRA design, and the RI at the maximum image height is considerably higher in the low CRA case.** This observation is a direct consequence of the **cosine fourth law**, which dictates that RI decreases as the chief ray angle increases. The lower CRA of the design inherently minimizes these illumination losses. Additionally, entrance pupil expansion in the low CRA design, where the more complex front lens group increases the off-axis entrance pupil, contributes to a more uniform illumination profile across the field.

**4.4. Modulation Transfer Function (MTF)**

The **MTF across the field of view for the low CRA design exhibits a slower roll-off and significantly smaller astigmatism than for the high CRA design.** The variation of astigmatism over the FOV is particularly pronounced for the high CRA designs (e.g., 40-degree CRA). This directly correlates with the reasons detailed in the analysis of field curvature, astigmatism (Section 4.4), and spherochromatism (Section 4.7). Fundamentally, the improved MTF performance in low CRA designs is a consequence of the more favorable chief ray angles entering the rear lens group, which allows for better correction of off-axis aberrations and chromatic effects. The higher the chief ray angle incident on the rear group, the more challenging it becomes to achieve high and uniform MTF across the field.

**5. Conclusion**

This study demonstrates a clear trade-off between optical system compactness and imaging performance when selecting CMOS sensors with varying Chief Ray Angles (CRA). While **higher CRA designs offer the advantage of achieving a smaller package size**, enabling more compact camera modules, **lower CRA designs consistently yield superior optical aberration correction and better align with inherent sensor characteristics**, thereby ensuring significantly improved overall imaging performance.

A notable practical consequence of the aggressive optical designs often required for high CRA sensors is the **difficulty in achieving effective athermalization across the field of view**. This limitation can lead to significant performance degradation under varying temperature conditions.

Therefore, for applications where **space constraints are not paramount and optimal image quality is the primary objective, a low CRA sensor is unequivocally the preferred choice.** The benefits in aberration control, light collection efficiency, and image uniformity offered by lower CRA designs outweigh the packaging advantages of high CRA solutions in such scenarios.

## RGBIR (Day/Night) Lens Portfolio

RGBIR is a popular term for lenses optimized for operation in both daylight and low-light conditions. Such products require specialized design considerations, broadband AR coatings (BBAR) with low reflectivity (R%), dual-bandpass filter with high transmissivity (T%) in the VIS and IR bands, and specific manufacturing techniques to provide the best possible image quality.

If done right, an RGBIR lens can significantly improve focus, brightness, and resolution over conventional lenses.

The enhanced infrared sensitivity of RGBIR lenses is often paired with a dedicated infrared illumination source enabling night vision applications and use cases such as biometric authentication, gaze tracking, and gesture recognition.

IR-corrected lenses are used in many applications across different industries and can be referred to as RGBIR (e.g., automotive), Day/Night (e.g., Security and Surveillance), and also hyperspectral (e.g., medical).

## Key Technologies

**Dual-Bandpass Filters**For many camera applications, Infrared (IR) is an unwanted component of the light spectrum and is often blocked using IR cut-off filters that block the transmission of the infrared while passing the visible (VIS). The Sunex IRC4x family of dual-bandpass filters on the other hand are specifically designed to allow the visible and a narrow IR-band to pass through simultaneously. Typical configurations are VIS+850 and VIS+940. Sunex also offers single-band IR filters, and custom filter designs.

All graphs are for illustration purposes only. The individual lens performance can be different.

## M12 lens sourcing strategy whitepaper

- Source: https://sunex.com/2025/09/22/choosing-the-right-sourcing-strategy-for-m12-lenses/
- Summary: OEM vs. intermediary vs. internet-platform total cost of ownership analysis

There are three M12 lens sourcing channels — internet/commodity platforms, catalog intermediaries, and direct OEM partnerships — each with different tradeoffs in cost, quality, supply security, and customisation capability. For prototyping, internet lenses are fast and adequate. For production programmes, OEM-direct partnerships consistently deliver lower total cost of ownership and fewer programme-threatening surprises.

This case study maps each sourcing channel to the development stage where it delivers best value, with real-world examples of what goes wrong when engineers lock in the wrong channel too early.

**Balancing Cost, Risk, and Performance in Robotics, Industrial Automation, Embedded Vision, and Drone Imaging**

Selecting the right lens sourcing strategy has direct, long-term consequences on image performance, supply continuity, and program economics. The market currently offers three distinct channels: internet platforms, catalog-style intermediaries, and direct OEM partnerships. Each offers benefits at different phases of development, but each also carries distinct risks that grow or shrink as projects move from concept to fielded products.

This whitepaper provides a practical framework to evaluate the trade-offs among the three channels. It integrates real-world scenarios across robotics, industrial automation, embedded vision, and drone imaging, and it attempts to quantify lifecycle impacts using a Total Cost of Ownership (TCO) approach to lens sourcing.

## Watch: 3 Essential Questions to Ask Your M12 Lens Supplier

The conclusion is straightforward: Internet platforms and intermediaries are potentially valuable options for speed and flexibility in early phases, but mission-critical systems and volume production benefit most from an OEM partnership that aligns optical design, quality, and supply with the product roadmap, and fostering these relationships from the very beginning of a project can pay dividends in terms of Total Cost of Ownership.

Figure 1. Comparison of sourcing channels across key success factors.

## What are the three main sourcing strategies for M12 lenses?

M12 board lenses are the workhorses of compact imaging, enabling a wide range of FOV (field of views) and F/#’s in small packages and integrating with modern CMOS sensors across a diverse range of devices. As sensor performance improves and mechanical envelopes shrink, optics must carry a greater burden for contrast, distortion control, relative illumination, and environmental stability.

**Robotics**→ Object detection, navigation, bin picking**Industrial automation**→ Inspection, defect detection, process optimization**Embedded vision**→ Compact consumer and enterprise devices**Drone imaging**→ Aerial mapping, agriculture analytics, surveillance

At the same time, the supply landscape has broadened. Low-cost marketplaces put thousands of lens SKUs within a click. Intermediaries curate selections, maintain regional inventory, and reduce friction for small orders. OEM lens manufacturers design, produce, and support lenses at scale with guarantees on performance, process control, and lifecycle. Understanding where each channel fits means separating what matters in the lab from what matters in the field across years of production.

**Internet Platforms**Marketplaces such as Amazon and Alibaba offer unmatched convenience and breadth. They are ideal for quickly assembling a bench of candidate lenses to sample fields of view, mechanical clearances, and basic image quality. However, listings may draw from anonymous, mixed, or end-of-life lots; coating recipes and glass sets may vary over time; and there is rarely a roadmap commitment or any traceability. For these reasons, internet lenses are effective tools for exploration but are risky foundations for any product that requires repeatability, certification, or long-term serviceability.

**Intermediaries and Catalog Resellers**Intermediaries create value by pre-screening suppliers, carrying inventory, and simplifying procurement for small runs. They are particularly helpful between proof-of-concept and pilot, when teams need a consistent part number without committing to an OEM minimum order or a custom design. Yet intermediaries are constrained by their upstream sources. They typically do not control most aspects of the design, including coating, glass sourcing, or process, and they cannot guarantee that a given SKU will remain in production for the lifetime of your product. When volumes increase or performance margins tighten, such constraints can force an unplanned redesign.

**OEM Lens Manufacturers**OEMs design and manufacture lenses, manage material supply chains, and validate performance against application-specific or even customer-specific requirements. A mature OEM partnership extends beyond the PN; it includes engineering collaboration (field of view and distortion trade-offs, stray light, spectral response), process control (custom parameters, binning, yield management), and lifecycle planning (EOL policies, alternatives, second-source strategy). Although the unit price may be higher at the outset, and lead times require planning, the risk profile and total program cost are significantly lower in mission-critical, multi-year, and high-volume scenarios. For building long-term, win-win relationships where both the customer and the supplier can bring their full strengths to bear, this is the best option.

## Which sourcing channel is best for the Product Development Cycle?

Product development is often a series of changing constraints. Early on, speed dominates: teams need to consider multiple performance envelopes, mounting options, and ISP pipelines. As prototypes evolve into pilots, repeatability and early supply assurances take priority. At design freeze and launch, quality and reliability take precedence, and lifecycle commitments become non-negotiable. To some extent, these shifting constraints map naturally to the strengths of each sourcing channel. The trick is not to get locked into a path that is not scalable to your ultimate goal.

During concept and POC phases, internet platforms can supply breadth and immediacy, if not exactly meeting the spec. Engineers can sample a dozen lenses very quickly to validate basics, such as the field of view, F/#, and first-order mechanical parameters. The goal is to learn quickly, not to lock architecture on a commodity part.

In Pilot and Beta, intermediaries can add value while also having the ability to support small, ongoing projects looking forward. They reduce friction for “sub-MOQ” builds, provide a single catalog with multiple options, and can maintain a buffer stock while customers complete qualification testing. The risk is that the upstream lens may change subtly between lots or disappear altogether (EOL), through no fault of the supplier themselves.

At Design Freeze and Production Ramp, OEMs become essential. The discipline of a controlled design, documented process flow, and optionally active alignment to the sensor removes variability that would otherwise manifest as yield loss, RMAs, or artifacts in the image. In small quantities, this may be tolerable, as you can hand-sort, but in production, it is unacceptable. Reliable OEMs also lock product lifecycles to the customer roadmap, preventing surprise discontinuities during scale-up and mass production, and for aftermarket support. If the customer started out with an “internet lens,” which somehow made it this far in the design cycle, this is where TCO starts to become a major issue for so-called inexpensive lenses. The cost and schedule stress of redesigning and implementing new optics at this stage typically ripples far beyond the lens itself.

Figure 2. Conceptual suitability of each channel across the major development stages.

## When does direct OEM sourcing become the right choice for M12 lenses?

**Robotics and Warehouse Automation**A robotics integrator building a bin-picking camera used inexpensive internet-sourced lenses to evaluate several fields of view. The prototypes worked until thermal cycling at the factory floor revealed focus drift and increased distortion at temperature extremes. Transitioning to an OEM design with thermally balanced materials and tighter assembly tolerances stabilized focus and cut field failures by more than half. Redesign was required, but was done early on, and the cost was more than offset by avoiding RMAs and line downtime.

**Industrial Automation and Semiconductor Inspection**In defect inspection, modulation transfer function (MTF) consistency directly affects false positives. A machine builder using standard catalog lenses encountered lot-to-lot variation that pushed MTF just below the acceptance window for some lots. After consulting an OEM lens manufacturer, the OEM suggested using binned (sorted) elements and specially controlled assembly torque and case-specific OQC testing. Qualification passed on the first attempt, and the program recovered three months of schedule with significant improvement in false positives (yield rate).

**Embedded Vision Devices**A compact enterprise device ramped from 200 to 30,000 units per year. Its catalog lens was discontinued midway through ramp, triggering an unexpected optical redesign and FCC re-test, resulting in sudden costs and delays. A subsequent OEM engagement was able to deliver a mechanically drop-in lens replacement optimized for the same sensor with consistent shading and improved relative illumination, locked to a five-year supply plan.

**Drone Imaging and Multispectral Analytics**An agriculture drone platform needed RGB and near-IR imagery while meeting strict mass and vibration constraints. Early experiments with off-the-shelf lenses exposed coating degradation and decenter sensitivity under vibration profiles as a key spec. An OEM solution combined a dual-channel design with IR-optimized coatings, ruggedization and active alignment to the sensor, enabling repeatable NDVI computation and faster regulatory approvals.

## What are the supply chain risks of internet-sourced lenses in production?

Total Cost of Ownership (TCO) aggregates all costs required to deliver and sustain a product: engineering hours, yield losses, RMAs, replacements, qualification delays, and the risk-weighted cost of supply disruption. Internet platforms often minimize unit price but externalize many of these costs; intermediaries reduce some variability but do not eliminate upstream risk; OEMs reduce lifecycle costs through design control, process discipline, and roadmap alignment.

Factor | Internet Platforms | Intermediaries | OEM Manufacturers | | Redesign Costs | Very high | Moderate | Minimal | | RMA / Field Failures | Frequent, expensive | Lower | Lowest | | Qualification Delays | Likely | Less common | Minimal | | Yield Optimization | None | Limited | Fully controlled | | Redesign Costs | Very high | Moderate | Minimal | | Engineering Support | None | Limited | Full optical/system support
A simple way to visualize this is to model cumulative lifecycle cost over time. Internet-sourced parts start low but accelerate as failures and redesigns accumulate. Intermediary-sourced parts fare better, but may still increase due to limited control over process drift or EOL. OEM parts often – not always -start at a higher price but remain relatively stable over the product’s lifetime.

Figure 3. Conceptual TCO curves. Internet platforms minimize upfront price but often maximize lifecycle cost; OEM curves are higher initially but flatter over time.

## How does Sunex’s OEM partnership model reduce M12 lens program risk?

**Start fast, but do not anchor architecture to commodity parts **is the key. Use internet platforms to accelerate learning but treat those lenses as disposable tools for discovery. Once the optical envelope is understood, move to controlled sources.

When a pilot demands a few dozen to a few hundred units, intermediaries can be a pragmatic bridge. Validate batches aggressively: check MTF, distortion, shading, and environmental stability across multiple lots. Confirm the reseller’s view of upstream continuity before committing to field trials. Even at low quantities, keep one eye on the future. Could this product ramp to significant volumes? Will your initial choices scale seamlessly? Will this company/product be here to support me in 5 years?

For ramp-up and production, or for those projects which will invariably ramp to high volumes, choose an OEM partnership from the outset that is aligned to your sensor, packaging, and lifecycle plan. Define performance windows and test methods jointly; consider active alignment to stabilize focus and tilt; document change-control and EOL procedures; and synchronize forecasts so material supply and capacity scale with demand.

Finally, incorporate TCO into milestone reviews. A lens that saves a few dollars in the BOM can cost hundreds of thousands of dollars in redesigns and field interventions later. Use TCO models to make these hidden costs visible before they materialize.

## How should my Decision Checklist for M12 lenses look?

- Have we validated optical performance across temperature and vibration to production limits?
- Is there documented lot traceability and change control for the lens and key materials?
- Do we have an agreed roadmap and EOL policy matched to our product lifecycle?
- Are yield, binning, and active alignment options defined to protect margins at scale?
- Does the supplier offer direct Engineering and QC support?
- Have we stress-tested supply continuity with realistic forecast scenarios?

Intermediaries should be acknowledged as important participants in the ecosystem. Many provide tangible value: local inventory, simplified procurement, and pragmatic assistance for early deployments. The argument presented here is not that intermediaries lack merit, but that their role is structurally different from a design-and-manufacture partner. This article’s recommendation is therefore not a criticism; it is a risk-managed allocation of roles that aligns channel strengths with project characteristics. When intermediaries source from OEMs, the collaboration can be positive, provided that plan-of-record parts, documentation, and lifecycle commitments remain robust.

# Conlusions

Sourcing choices determine more than unit price: they influence image quality, yield, schedule, and customer experience for years to come. Internet platforms and intermediaries accelerate learning and simplify early builds; OEM partnerships stabilize products, reduce lifecycle cost, and protect brand equity in the field. For mission-critical systems in robotics, industrial automation, embedded vision, and drone imaging, the data and experience converge on a simple rule: prototype fast, then productize with an OEM.

While internet platforms and intermediaries can play roles early in development, OEM partnerships offer unmatched advantages:

- Custom design integration
- Guaranteed lifecycle continuity
- Optimized yields and reduced RMAs
- Engineering collaboration and value-added services, such as active alignment

## MTF in digital imaging — practical guide

- Source: https://sunex.com/2025/08/12/understanding-mtf-in-digital-imaging-why-it-matters-and-how-to-interpret-it/

## What is MTF, and why does it matter for lens selection?

MTF (Modulation Transfer Function) is the single most important metric for predicting how sharp and detailed your lens images will be. Higher MTF = better contrast at fine detail — directly impacting detection accuracy in machine vision, ADAS, and medical imaging. A good rule of thumb: target MTF >40% at the Nyquist frequency of your sensor.

MTF describes how well a lens transfers contrast across a range of spatial frequencies. A perfect lens retains 100% contrast (MTF = 1.0) at all frequencies — real lenses lose contrast as detail gets finer. This article explains how to read MTF graphs, what values to target, and how to use Sunex’s interactive MTF Simulator.

When evaluating or designing an imaging system, one of the most important (and often misunderstood) specs is the Modulation Transfer Function (MTF). MTF describes how well a lens can transfer contrast at varying levels of image detail (spatial frequencies). In other words, it shows how sharp the image will be.

But just reading an MTF graph isn’t always enough. That’s why we created the MTF Simulator—a visual tool that helps you see how different MTF values affect image clarity.

## How do you read an MTF graph?

An MTF graph plots contrast (0–1) on the Y-axis versus spatial frequency on the X-axis (in cycles/mm). Some key features to look for:

- Higher MTF curve = better contrast at that level of detail
- Sagittal (S) vs. Tangential (T) curves indicate performance symmetry
- FOV performance variation

MTF curves provide a quantitative idea of how a lens will perform at certain spatial frequencies. Our MTF simulator connects the quantitative to the qualitative, making it easy to understand the impact a value of MTF will have on your image.

## How can I use the Sunex MTF Simulator to evaluate a lens?

Here’s how it works:

- Choose your target type:

– Sine wave or square wave

– For square waves, the simulator assumes harmonic MTF values drop off as 1/frequency. This is generally accurate at mid to high frequencies but may not reflect low-frequency, high-MTF edge cases. - Select a spatial frequency:

– Explore coarse vs. fine detail. Input the required spatial frequency. - Set an MTF value between 0 and 1:

– Simulate how much contrast your lens retains at that level of detail.

The simulator shows a perfect input target and a corresponding image impacted by your selected MTF value, helping you visualize how contrast loss affects clarity.

Visualize the impact of MTF using our interactive MTF Simulator.

## What MTF value should I target for my imaging application?

MTF is more than a theoretical metric—it’s the key to understanding how your lens and sensor work together to produce sharp, high-contrast images. By interpreting MTF graphs, matching sensor specs, and accounting for application-specific trade-offs, you can make smarter imaging decisions.

Ask our Sunex support team to get more information on MTF and try our MTF Simulator to get a visual feel for how optical performance translates to image quality.

## Image circle and sensor format

- Source: https://sunex.com/2026/03/26/image-circle-and-sensor-format/

The lens image circle must equal or exceed the diagonal of your camera sensor — or you get vignetting (dark corners) that ruins image quality. If it is larger than needed, you are paying for optical coverage you are not using. Getting image circle matched to sensor format is the first step in any lens-sensor system design.

This article explains the relationship between image circle and sensor format, how to calculate FOV from these parameters, and common mistakes engineers make when pairing lenses with sensors.

# Understanding the Relationship That Determines Your System's Field of View

In this white paper:

- What is a lens image circle, and why does it matter?
- How do I match a lens image circle to my camera sensor format?
- What happens if the image circle is smaller than the sensor?
- How does sensor format affect the field of view of my camera system?
- What sensor formats are commonly paired with M12 lenses?
- Conclusion

When engineers set out to build an imaging system, the conversation usually starts with field of view; how wide, how narrow, how much of the scene needs to be captured. From there it is tempting to look up a focal length, find a lens that matches, and move on. What often goes unexamined until something goes wrong is the relationship between the lens’ image circle and the physical dimensions of the sensor. That relationship is not a secondary detail. It is the foundation on which field of view, resolution, and image quality are all built.

This article walks through what image circle is, how it connects to sensor format, and why both must be understood together to arrive at a system that captures exactly what it is supposed to. Along the way, we look at how pixel pitch fits into the picture, how different coverage geometries create different requirements, and how seemingly minor specification mismatches produce problems that are easy to avoid once the underlying geometry is clear.

## What is a lens image circle and why does it matter?

A lens does not project a rectangle. It projects a cone of light that produces a circular footprint on the image plane. Within that circle is the region where the lens delivers usable brightness, sharpness, and geometric accuracy. The diameter of that region is the image circle.

Every lens is designed around a specific image circle. During the design process, the optical engineer defines a maximum field angle or image height, and the lens is optimized to perform within that boundary. The result is a lens that performs well up to a certain diameter, and with diminishing returns beyond it. That diameter, doubled from the maximum image height, is the nominal image circle.

The nominal image circle is the specification you will find on a datasheet. It is the designer’s intended coverage diameter. In practice, the lens continues to project some usable light beyond this boundary — what Sunex defines as the true image circle, measured at the point where relative illumination falls to 10%. For wide-angle and fisheye designs, the true image circle typically extends 10–15% beyond the nominal value. For narrower field lenses, it can be 25–30% beyond. But that additional coverage is not guaranteed to be uniform or fully corrected, which is why the nominal value remains the proper basis for sensor compatibility decisions.

The image circle must fully cover the sensor diagonal, or the corners and edges of the captured image will fall into vignetting or hard clipping. This is a geometric constraint — it has nothing to do with whether the lens is functioning correctly.

When a lens is described as a “1/3-inch format lens,” that description is shorthand for the image circle it was designed to cover, in this case, a circle whose diameter matches the diagonal of a 1/3-inch sensor (6mm). Pairing that lens with a larger sensor means asking it to cover an area it was never designed for. The lens will not fail, but the sensor corners will.

## How do I match a lens image circle to my camera sensor format?

Sensor format notation — 1/4″, 1/3″, 1/2″, 2/3″, 1″, and so on — is one of the more persistently confusing conventions in imaging. The fractions do not represent the width or diagonal of the sensor in inches. They are inherited from the era of vidicon vacuum tube cameras, where the fraction referred to the outer tube diameter. The actual active imaging area of a modern solid-state sensor is roughly two-thirds of what the notation implies. A 1/2″ sensor is not half an inch wide — its active area is closer to 6.4mm × 4.8mm.

This matters because the format name alone is insufficient for optical system design. What matters is the actual physical dimension of the active area, and specifically the diagonal, which is the distance from corner to corner across the sensor’s imaging surface. That diagonal is the number that must be matched against the lens image circle.

The table below lists common sensor formats with their actual dimensions and the minimum image circle needed to cover each format fully.

1/4″ | 3.2 | 2.4 | 4.0 | 4.0 mm | 1/3″ | 4.8 | 3.6 | 6.0 | 6.0 mm | 1/2.5″ | 5.8 | 4.3 | 7.2 | 7.2 mm | 1/2″ | 6.4 | 4.8 | 8.0 | 8.0 mm | 1/1.8″ | 7.2 | 5.4 | 9.0 | 9.0 mm | 2/3″ | 8.8 | 6.6 | 11.0 | 11.0 mm | 1″ | 13.2 | 8.8 | 15.9 | 15.9 mm | APS-C | 23.5 | 15.6 | 28.2 | 28.2 mm | Full Frame (35mm) | 36.0 | 24.0 | 43.3 | 43.3 mm
*Table 1: Common sensor formats, their physical active area dimensions, and the minimum image circle required for full corner-to-corner coverage.*

When working with a specific sensor, always pull the actual dimensions from the manufacturer’s datasheet rather than relying on the format label. Variations of a few tenths of a millimeter exist between manufacturers and product generations, and for tight image circle margins, those differences matter.

The minimum image circle column above represents the sensor diagonal, the hard floor for lens compatibility. In practice, specifying a lens whose nominal image circle exceeds the sensor diagonal by 5–10% provides meaningful margin against manufacturing variation, temperature-related shifts in the optical path, and focus changes across the working distance range.

**Pixel Pitch: Resolving Power Beyond the Image Circle**Alongside physical format, pixel pitch is the other sensor specification that directly constrains lens selection. Pixel pitch is the physical size of each individual pixel, measured in micrometers. Modern imaging sensors range from below 1µm in compact consumer devices to 5µm and above in machine vision and scientific cameras.

A lens has a finite resolving power, and that limit is often expressed as a minimum pixel pitch, which means nothing more than the smallest pixel the lens can usefully resolve. If a lens is rated for a 1.67µm pixel pitch, it can resolve detail down to that level. The key asymmetry is this: a lens can work with a sensor whose pixel pitch is equal to or slightly larger than its rated minimum, but it cannot compensate for a sensor with a smaller pixel pitch than it is designed to resolve.

Well-matched system | 1.67 µm | 1.67 µm | Full resolution delivered |
Acceptable — sensor pixel slightly larger | 1.67 µm | 2.0 µm | Works well |
Mismatch — lens cannot resolve sensor pixels | 3.45 µm | 1.67 µm | Image appears soft |

*Table 2: Pixel pitch compatibility between lens and sensor determines whether the full resolving capability of the sensor can be utilized.*

Put simply: if the sensor’s pixels are finer than the lens can resolve, the lens becomes the bottleneck. The image will appear soft regardless of the sensor’s megapixel count. Selecting a lens whose pixel pitch specification matches the sensor, or runs slightly finer, ensures the sensor’s resolution is not being wasted. The applications engineers at Sunex can provide the minimum pixel pitch a lens can resolve upon request, making direct comparison to sensor specifications straightforward during the selection process.

## What happens if the image circle is smaller than the sensor?

Field of view is the angular extent of the scene that the imaging system captures — stated as horizontal FOV, vertical FOV, or diagonal FOV. It is the central performance requirement for most imaging applications. And yet it is not a property of the lens alone. It is a property of the combination of lens and sensor.

The same focal length produces a different field of view on every sensor format. A 6mm lens on a 1/3″ sensor delivers roughly 44° horizontal field of view. The same 6mm lens on a 1″ sensor delivers roughly 75°. Move that lens to an APS-C sensor and the horizontal FOV expands further still. The lens has not changed, what has changed is the size of the rectangular window being cut from the image circle.

Field of view is a system specification, not a lens specification. Quoting a focal length without specifying the sensor format it is paired with leaves the actual field of view undefined.

*Figure 1: Illustration of two systems with the same sensor format, the same lens EFL, but two different lens image circles.*

This is one of the most common sources of specification confusion in imaging system procurement. A lens that delivered the right field of view on one project gets carried over to a new project using a different sensor, and the coverage angles change completely. The lens is doing what it always did; the sensor format is doing something different with it.

The underlying relationship is straightforward: a wider sensor dimension or a shorter focal length produces a wider field of view. A narrower sensor or a longer focal length produces a narrower one. This applies independently to the horizontal and vertical axes, which means changing the sensor format changes both FOV values simultaneously, in proportion to the change in physical sensor dimensions.

**Coverage Mode: What Part of the Image Circle Is the Sensor Using?**

Beyond the simple question of whether the image circle covers the sensor diagonal, there is a more nuanced question about how the image circle and sensor geometry relate to each other. Depending on the application, the answer changes what counts as an adequate image circle.

When the image circle is larger than the sensor diagonal (overfill) the sensor sits entirely within the optimized zone of the lens. Every pixel on the sensor receives well-corrected, uniformly illuminated light. This is the most robust configuration and the one that provides the most margin against real-world variation.

When the image circle matches the sensor diagonal precisely (full frame coverage) the sensor corners land right at the edge of the image circle. The lens is performing at its design limit at those corners, which demands a well-controlled design and careful manufacturing. This configuration is common in high-resolution industrial and broadcast lenses, where the sensor is as large as possible and the lens must be optimized all the way to the corner. Sunex’s large-format lens series, designed for 1″, APS-C, and full-frame sensors, addresses exactly this requirement, maintaining controlled MTF performance out to a 43mm image circle diameter.

When only the horizontal dimension needs to be covered (full horizontal coverage) the image circle may be smaller than the sensor diagonal, as long as it spans the full width. The corners of the sensor fall outside the image circle and are dark, but the horizontal field of view is fully captured. This configuration is used in some panoramic and wide-field surveillance applications where the vertical extent of the scene is less important than the horizontal sweep.

The most demanding configuration from an image circle standpoint is circular fisheye containment, where the entire image circle, the complete 360° or 180° disk projected by the lens, must fit within the sensor boundaries. This requires the image circle diameter to be smaller than the sensor’s smaller dimension, not just the diagonal. A fisheye lens with a 5.6mm image circle, for example, needs a sensor whose height is at least 5.6mm for the full circular image to land entirely within the active area.

*Figure 2: Image Circle vs. Sensor Format [**Full Frame Overfill · Full Frame · Full Horizontal · Partial Frame · Circular Fisheye]**The same lens image circle produces different coverage geometries — and different effective fields of view — depending on sensor format and application coverage requirements.*

## How does sensor format affect the field of view of my camera system?

The coverage mode question becomes most consequential when it is not addressed during system design, and the mismatch shows up during integration. The following scenario illustrates how image circle and sensor geometry interact in a fisheye application, and the range of solutions available when the initial combination does not meet the coverage requirement.

Consider a system designed to capture a 180° × 180° full-circle fisheye image, with the complete circular image fully contained on the sensor. The selected lens has an image circle of 5.6mm. The selected sensor has an active area of 8.06mm × 4.54mm.

Furthermore, the lens itself produces an acceptable FOV across the horizontal and the diagonal, 173°, and for most applications, this is the standard goal. But this application requires the entire fisheye circle to sit inside the sensor boundaries. That means the image circle diameter of 5.6mm must fit within the shorter sensor dimension, which is 4.54mm vertically. It does not. The circular image overflows the top and bottom of the sensor, and the resulting footage shows the fisheye disk cut off at the vertical edges.

This is not a lens defect. The lens is projecting exactly the image circle it was designed to produce. The problem is that the sensor’s shorter dimension is smaller than the image circle diameter — a geometric constraint that no amount of refocusing, iris adjustment, or firmware tuning can resolve.

Once the geometry is understood, the paths forward are clear. The right solution depends on which element of the system can be changed and what the application can tolerate.

The first option is to find a lens with a smaller image circle that still achieves a comparable field of view. If a lens can produce a similar FOV with an image circle at or below 4.54mm, the complete fisheye disk will land within the sensor’s vertical span. The full circular image is preserved.

The second option is to use a lens with the same or larger image circle but a wider field of view, one that reaches the full 180° diagonal. In this case, the circular image still overflows the sensor vertically, but it does so at 180°: the horizontal edges of the sensor align with the 180° boundary of the fisheye, giving a usable semicircular or full-circle crop depending on the exact geometry. The clipping becomes intentional and predictable rather than arbitrary.

The third option is to keep the lens and change the sensor. The requirement is a sensor whose shorter dimension is at least equal to the image circle diameter, 5.6mm or more vertically. A sensor with an active area of 6.77mm × 5.66mm, for example, clears this threshold. The lens is unchanged; it now projects its full circular image within the sensor boundaries. This option must also consider the lens’ new FOV on the new sensor, for a change like this one will also affect it (as we previously covered in Part 3 of this article).

The fourth option is mechanical: rotate the sensor 90°. With the sensor’s longer dimension (8.06mm) now running vertically, the 5.6mm image circle easily fits within the frame. The circular image is fully contained vertically; the left and right edges of the sensor extend beyond the image circle horizontally, but for applications that only need vertical containment, this may be entirely acceptable.

Each of these options changes something different about the system, the lens, the sensor, or the orientation, but all of them stem from understanding the same underlying constraint: image circle diameter relative to sensor dimensions, driven by the specific coverage geometry the application requires. Sunex applications engineers work through exactly this kind of analysis as part of lens selection consultations, matching image circle specifications from the M12 and large-format portfolios to sensor geometry and application coverage requirements before any hardware is committed.

## What sensor formats are commonly paired with M12 lenses?

Bringing together image circle, sensor format, pixel pitch, and field of view into a coherent system specification is less complicated than it might seem once the relationships are understood. The following framework consolidates the key decision points.

**Start with the sensor’s actual physical dimensions.**

Pull the active area width, height, and diagonal from the sensor manufacturer’s datasheet. It is important to not estimate the size from the format label. Measuring or looking up the actual values is strongly advised. For most applications, the diagonal is the minimum image circle your lens must provide for full-frame coverage.

**Define what coverage geometry the application actually needs.**

Full frame, full horizontal, overfill, or circular containment each place different demands on the image circle. Establishing this early prevents the common mistake of specifying a lens that covers the sensor diagonal but fails to meet a more specific coverage requirement that the application turns out to have.

**Determine the required field of view and the focal length it implies.**

State the FOV requirement in degrees, horizontal, vertical, or both, and calculate the focal length needed to achieve it on the chosen sensor format. Horizontal and vertical FOV are independent calculations based on the sensor width and height respectively. Because FOV and sensor format are linked, changing either changes the other: be explicit about both. The Optics Wizard at sunex.com/support can further help calculate the Effective Focal Length needed, depending on the FOV and sensor size.

**Verify image circle coverage with margin.**

Identify lens candidates that meet the focal length requirement and confirm their nominal image circle covers the required sensor dimension by at least 5–10%. The nominal image circle is the design target, and real lenses will fall within a tolerance band around it. Margin ensures the system stays within specification across that variation. Sunex publishes nominal image circle on all lens datasheets, and the Optics Wizard at sunex.com/support can further filter lens options by sensor format and coverage requirement, narrowing the candidate list quickly.

**Match pixel pitch between lens and sensor.**

Confirm that the lens’s pixel pitch specification is equal to or smaller than the sensor’s pixel pitch. A lens with a coarser pixel pitch spec than the sensor cannot resolve the sensor’s pixels, the image will be soft regardless of sensor resolution. This is a frequently overlooked constraint that is easy to check and worth verifying explicitly.

**Validate with hardware.**

Flat-field images across the full sensor area confirm uniformity. MTF measurements at the sensor corners confirm that the edge of the image circle is delivering usable sharpness. If the application operates across a temperature range or at varying focus distances, validate at the extremes. Datasheet specifications describe design intent; hardware measurements confirm actual system behavior. Sunex recommends testing production-representative lens samples rather than relying on nominal values alone, particularly for applications with strict uniformity or corner performance requirements.

## Conclusion

Image circle, sensor format, and field of view are not three separate specifications to be checked independently. They are three expressions of the same underlying geometry. The image circle sets the boundary of what the lens can cover. The sensor format determines what portion of that coverage is captured and at what field angle. Pixel pitch determines whether the sensor can take full advantage of the lens’s resolving capability. Together, these parameters define the actual performance of the imaging system, not the performance of the lens in isolation.

The most common problems that arise from misunderstanding this geometry are also among the easiest to avoid: image clipping that is attributed to lens quality but is actually a coverage mismatch, soft images on high-resolution sensors paired with insufficient lens resolving power, and field-of-view errors that appear when a focal length is carried over to a different sensor format. In each case, understanding the lens-sensor relationship before hardware is selected eliminates the problem before it becomes one.

Sunex’s lens portfolio spans image circles from under 4mm through 43mm, covering sensor formats from 1/4″ through full frame, with pixel pitch specifications down to 1.67µm. The Optics Wizard and AI-powered Optics Consultant at sunex.com/support provide guided lens selection based on sensor format, coverage requirements, field of view, and working distance — and Sunex applications engineers are available to work through more detailed system specifications where standard tooling is not sufficient.

1 Overview 
Optical distortion is un-avoidable for ultra wide-angle and fisheye lenses. Sunex Dewarper Mini is a Adobe Photoshop compatible 
plug-in for processing distortion taken with Sunex miniature ultra wide-angle and fisheye lenses. It remaps the pixels such that the 
processed image is optimized for the intended application. This software is based on a new proprietary model developed by Sunex for 
real-world lenses. Unlike other distortion correction software, Dewarper Mini does not require that the lens follows the idealistic f-θ 
mapping. All distortion types can be modeled including our Tailored Distortion™ lenses. 
 
Key Features 
• Distortion cancellation: This feature compensates for the optically distortion in the lens. The resulting image is what one 
would see if the lens has zero optical distortion. If the horizontal field of view is greater than about 100 degrees, the off-axis 
objects may look stretched. This is caused purely by the fact that the lens is very close to objects, not the lens distortion itself. 
• Distortion tailoring: This feature allows one to optimize the amount of the distortion in the image. It can be used to simulate 
images taken with lenses having different amount of distortion (for example, our Tailored Distortion lenses). 
• One-shot panorama: This is a new projection method developed by Sunex for creating a 180° panorama from a single fisheye 
shot. This eliminates the process of stitching together multiple images. 
• Spherical and cylindrical panorama: This takes a circular fisheye image and expands it into spherical or cylindrical panoramic 
projections suitable for viewing with popular VR viewers such as Apple QuickTime. 
• 360 degree panorama: This is used to “unwrap” the 360 degree surrounding captured by a fisheye lens when it is pointing 
vertically. 
2 Installation 
Sunex Dewarper Mini is compatible with all image editors that accept Adobe Photoshop-compatible plug-ins such as follows: 
• Adobe Photoshop 7.0 and higher versions 
• Photoshop Elements 2 and higher versions 
• PaintShop Pro 7 and higher versions

Dewarper Mini v1.2 user guide 
Page 3 
The installation of the Dewarper Mini is simple. 
• Locate the plug-in folder for your program. Table 1 shows the typical directories used by popular programs

• Copy the “.8bf” file to plug-in folder of your program. 
• Open your image editor 
• Open a JPEG file or any 8-bit RGB files. 
• Dewarper Mini should now be accessible from the plug-in menu of your image editor under “Sunex”. 
3 Procedure 
The procedure for processing images is as follows: 
• Use your image editor to crop the image so that the horizontal width of the image matches the lens image circle. 
• Start the Dewarper Mini filter 
• Choose the Sunex lens used from the drop down box. 
• Choose the pixel pitch of the imager in µm in the drop down box. 
• Select an output image type from the drop down box. 
o Specify output parameters – the available options depend on the output image type selected. See next section for 
details. 
o If the “Transform X only” box is checked, the processing is only applied to the horizontal direction. 
• Click on the preview window to compare the image before and after processing. 
• Click on OK to process the full size image.

4 User Interface 
 
 
 
The user interface is straightforward and self-explanatory. The small preview window on the left shows the image in real-time as the 
output parameters are adjusted. Click anywhere within the preview window brings back the original image for quick comparison.

5 Examples 
5.1 Distortion Cancellation 
This compensates for the optical distortion in the lens. If the horizontal field of view is greater than about 100 degrees, the off-axis 
objects may look stretched. This is caused purely by the fact that the lens is very close to objects, not the lens distortion itself. 
Therefore, it is recommended that the horizontal field of view of the output image be kept <100 degrees.

5.2 Distortion Tailoring 
Choose this output to increase/decrease the amount of distortion in the image. First, select an output image horizontal field of view 
(HFOV). Then, use the “adjust distortion” slider to vary the amount of distortion. It is used for optimize the amount of distortion in a 
wide-angle shot, and to simulate the effect of a lens with different distortion. It achieves the effect of “field of view preserving 
zooming”.

Summary 
In digital imaging systems, Infrared (IR) filters are used to reduce a color shift that is created by the infrared sensitivity of digital sensors. The effect of 
an IR cutoff filter on standard CMOS or CCD sensors is most noticeable in the presence of a Near-IR source such as the sun. Images taken in the daylight appear 
bleached without an IR filter, as seen in Figure 1.A.). This effect is not as drastic in indoor settings because most fluorescent lights do not emit light with 
wavelength greater than 800 nm. For optimal use of lenses in both day and night situations, we recommend using an IR cutoff filter with an IR bandpass such as 
the Sunex IRC40 and Sunex IRC41 filters. These filters allow sensors to have good color contrast in the day while still allowing IR floodlights to be used during 
the nighttime.

## Microsoft Word - Impact of Lens Chief Ray Angle on Image Quality.doc  [PDF]

Page 1 
Impact of Lens Chief Ray Angle on Image Quality 
By Alex Ning, PhD 
January 31, 2005 
1. Introduction 
Lens chief ray angle refers to the angle of incidence of an off-axis ray passing through the center of the 
lens stop on the image plane. If the imaging medium is a silver-halide film, the chief ray angle would 
not make too much difference to the final image quality because the film grain has isotropic angular 
response. However, if the imaging medium is a CCD or CMOS imager, the lens chief ray has 
significant impact on the final image quality. This is because the basic imaging element (a pixel) of 
CCD/CMOS imagers does not have isotropic response. This paper exams the effect of lens chief ray 
angle on the overall image quality. 
2. Experiment 
The Micron MT9D011 imager is used with two different lenses: Sunex PN DSL746 with a 1G2P 
structure and a competitor lens (also a 1G2P lens). Two lenses have the same f-stop of 2.8. The Sunex 
lens is designed to limit the max. chief ray angle within 20 degrees at the corner of the imager. The 
max. chief ray angle of the competitor lens is 25 degrees. An uniform white background is captured by 
using both lenses. The result is shown as follows. 
Sunex DSL746 Competitor Lens 
 
 
 
As can be seen from the above figure, the DSL746 lens has more uniform response in terms of color 
and corner brightness. The ratio of corner brightness to the center is known as “relative illumination”. 
It is also clear that the white balance (ratios between G, B and R) is more consistent from center to the 
corner with DSL746 lens. This difference can be explained in terms of chief ray angle mis-match with 
the sensor. At off-axis field angles, the higher chief ray angle of the competitor lens is outside the peak 
response region of pixel micro-lens. This results in a reduction in the overall response at off-axis angles. 
With color imager the higher chief ray angle can also cause cross-talk between adjacent pixels of 
different color. The cross-talk causes the ratios between R, G and B to vary from center to corners. A 
typical result is that the center will tend to be warmer, and corners cooler, as shown in the above figure.

Page 2 
3. Relative Illumination and Relative Color 
The above described phenomenon can be measured using many commercially available programs such 
as PhotoShop and Jasc Paint Shop Pro. We would first read out the pixel values for each R, G and B 
channel in the center of the image. These values will be used as baseline numbers. We will then read 
out the R, G and B pixel values at each of the four corners. Relative illumination (RI) can be computed 
as the ratio of corner luminance Y (=0.3*R+0.59*G+0.11*B) to the center luminance. The white 
balance is represented by the ratio of R to B. If R/B >1, the image is warm. If R/B<1, the image is 
cool. Relative color (RC) is represented by the corner R/B ratio divided by the center R/B ratio. 
 
 
 
Center-R/B=150/149=100.6% 
Corner-R/B=99/101=98% 
Relative Color(RC)=(Corner-R/B)/(Center-
R/B)=97.4% 
 
Center Y=0.3*R+0.59*G+0.11*B=149.89 
Corner Y=0.3*R+0.59*G+0.11*B=100.4 
Relative illumination (RI) = 67% 
Center-R/B=150/115=130.4% 
Corner-R/B=99/101=93.3% 
Relative Color(RC)=(Corner-R/B)/(Center-
R/B)=71.6% 
 
Center Y=0.3*R+0.59*G+0.11*B=134.94 
Corner Y=0.3*R+0.59*G+0.11*B=89.38 
Relative illumination (RI) = 66% 
 
4. Conclusion 
Mobile imaging modules demand very short profile lenses. The short profile lenses tend to have very 
high chief ray angles. The high chief ray angle can be detrimental to the image quality given the limited 
angular acceptance of the micro-lens array on the imager. This paper demonstrates that a 5 deg 
difference in the chief ray angle can cause a significant relative color issue (only 71.6% of the ideal 
goal) on the Micron 1.3MP imager. An acceptable relative color value should be >95% but less than 
105% for a good imaging system.

Optical Low Pass Filters Theory and Practice 
 
Summary 
In a high-quality, digital imaging system which uses CCD and CMOS sensors , an optical 
low pass filter (OLPF) is used to eliminate color Moiré fringes. It is important to note 
that Moiré fringes must b e removed passively in the optical system and cannot be 
removed by post -processing the image . See the difference in figure 1. The left side 
shows an image from an optical system without an OLPF, the right side shows and image 
with the same optical system with and OLPF. 
 
Figure 1. Left, without the OLPF; Right, with the OLPF 
 
Theory 
Since CCD and CMOS sensors sample image information at regularly -spaced, discrete 
points called pixels each sensor has a frequency limit, called the Nyquist frequency , that 
is defined by the geometry of its pixels. This frequency is equal to the inverse of the two 
times the pixel pitch. If the lens passes spatial frequency that is greater than the Nyquist 
frequency of the sensor, it cannot be resolved by the sensor . Worse, s patial frequencies 
that are greater than the Nyquist frequency will cause aliasing artifacts . These 
phenomena are often observed as colorful fringes called Moiré fringes, on the image. 
 
An OLPF placed between the lens and the image sensor stops the optica l system from 
passing spatial frequencies greater than the Nyquist frequency of the sensor. The filter 
cuts the high frequency information and passes only the low frequency information, 
removing the Moiré fringes from the image. 
 
OLPFs are made of several layers of birefringent optical crystals cemented together. The 
number of layers and thickness of each layer is defined by the pixel spacing of the sensor

2 
and the application. It follows that each OLPF design must be tuned to a particular 
sensor and application. 
 
For color imaging, an IR cut -off function is often in tegrated into OLPF as well. A 
reflective IR cut-off coating can be applied to an external surface or an absorptive IR cut-
off filter layer can be added to the quartz layers. 
 
Practice 
• When installing the OLPF into the digital imaging system it must be placed be tween 
the lens and the sensor. The performance is dictated by the layer th ickness and any 
optical coatings on the external surfaces . The exact location along this z -axis does 
not affect the performance of the filter significantly. 
 
• We do not recommend affixing the low pass filter to the sensor cover glass or use it as 
a sensor cover glass! Due to surface quality imperfections it is recommended that the 
filter be place more than 1mm (>1mm) away from the sensor plane. No matter how 
tight the surface quality specification there are always scratches and digs on the order 
of the pixel size that will show up in the image as blobs or dust if the filter is too close 
to the sensor plane. 
 
• The x-axis and y-axis [length and width] orientation of the OLPF with respect to the 
sensor is important. For a 4:3 and 16:9 aspect ration sensors, ensure that the long 
edge of the filter is square with the long edge of the sensor. 
 
• The filter will function if the IR cut coating faces the sensor or faces away from the 
sensor. The optical performance is the same.

Lateral Color in Mobile Imaging Lenses 
By Alex Ning, PhD 
January 21, 2005 
1. Background 
Chromatic aberration (CA) is one of several aberrations that degrade lens performance. Other common 
aberrations include coma, astigmatism, and curvature of field. Chromatic aberration occurs because the 
index of refraction of the lens material varies with the wavelength of light, i.e. it bends different colors 
by different amounts as shown in Figure 1. This phenomenon is called dispersion. Minimizing 
chromatic aberration is one the goals of lens design and it is accomplished by combining glass elements 
with different dispersion properties. Three element lenses (3P or 1G2P) are popular for mobile imaging 
applications. However, the optical performance of all 3-element lenses is limited by lateral chromatic 
aberration, also known as lateral color. This aberration can only be eliminated using a 4-element design 
with a 2P2G configuration. This paper compares the lateral color of a 1G2P lens with a 2G2P lens. 
 
Figure 1. Chromatic aberration in lenses 
 
2. How to detect lateral color 
The two types of chromatic aberration are illustrated in Figure 1. 
• Longitudinal chromatic aberration causes different wavelengths to focus on different image 
planes. It causes degradation of MTF response – with different amounts for different colors. 
• Lateral chromatic aberration is the color fringing that occurs because the magnification of the 
image differs with wavelength. It tends to be far more visible than longitudinal CA. For a 
given amount of lens CA, the smaller the pixel size the more visible the lateral CA in the 
captured image. The lateral CA can measured in terms of number of pixels. In a good 
imaging system the lateral CA should be <1x pixel. 
The lateral color is most visible if one examines a black/white edge at an off-axis viewing angle. The 
black/white edge should be oriented almost perpendicular to the radius. For example, following is the

Page 2 
left side of a picture taken with a 1G2P lens (Sunex PN DSL746). All images and analysis were done 
using a Micron 2MP (1600x1200) demo board with 2.8 µm pixel pitch. 
 
 
With a 2P2G design (Sunex PN DSL871/872) the lateral color is eliminated. As a result, the optical 
resolution is increased.

Vertical lines are not

“Rainbow” effect

3. Measurement of Lateral Color 
The amount of lateral color can be measured using commercially available software (ImaTest at 
http://www.imatest.com/). This program examines the transition from black to white at an off-axis edge 
for each primary color, and then calculates the amount of chromatic aberration at that edge. 
 
1G2P lens 2G2P lens 
 
 
The blue channel transition (the blue color curve) 
occurs before the red channel (red color curve). 
The distance between the two curves at 50% edge 
response is 2.1 pixels. This represents 0.468% of 
the distance to the center of the picture. This implies 
that there is 0.468% difference in magnification 
between the blue and red channel in this lens. 
 
The blue channel transition occurs at nearly the same 
location as the red and green channels. This results in 
very little chromatic aberration. The separation 
between the blue and red is insignificant (0.171 pixel) 
in comparison to the size of the pixel. 
 
 
4. Conclusion 
With the industry trend towards higher pixel count image sensors with smaller pixel sizes the lateral 
chromatic aberration of a 3-element lens will become a major problem. For the Micron 2M imager 
(MI2010) with a 3-element lens, the lateral color can be 2 or more pixels. Aberration on this order 
significantly reduces the optical resolution and MTF at off-axis viewing angles resulting in an apparent 
decrease in image detail. 
 
For next generation mobile imagers with higher resolution and smaller pixel spacing more sophisticated 
lens designs, such as the Sunex DSL871 and DSL872 with a 2G2P structure, are required to eliminate 
the lateral color. These 4-element lens designs allow the end-user to take full advantage of the increased 
imager resolution.

Plastic vs. Glass Optics: Factors to Consider
(part of SPIE “Precision Plastic Optics” short course note)
by Alex Ning, Ph.D.
Why Plastic Optics ?
Glass and plastic optics each has its own unique advantages. The properties of glass
materials are very different from that of plastic materials. There are literally hundreds of
different glass materials available from well-know suppliers such as Schott, Hoya and
O’hara for making glass optics. The choice for plastic materials is limited only to about
half dozen. The attached table lists the currently available plastic materials, and their key
properties. Generally speaking, glass materials are harder and more durable than plastic
materials. Glass materials are also more stable over a wider temperature range and
humidity environment than plastic. Glass is much heavier than plastic (by a factor of 2.5x
to 4x). The large selection of glass materials allows the designer to chose materials with
desirable optical properties to gain better optical performance. This kind of freedom is
limited with plastic materials. However, plastic optics offers other design freedoms that
are not achievable or economical with glass optics (see below).
The manufacturing processes for glass and plastic optics are entirely different. Glass lenses
are made by a grinding and polishing process whereas precision plastic lenses are made by
injection-molding. The differences in manufacturing process provide plastic optics some
unique advantages as follows:
High-volume production capability and low manufacturing cost: Injection molding
process allows very high volume production, and the unit cost can be very low. Though it
is possible to achieve moderately high volume production with glass optics also, it is
virtually impossible to realize the same cost reduction because the grinding and polishing
process is inherently time-consuming and labor-intensive.
Design sophistication: The grinding and polishing process makes difficult and very un-
economical to produce surface shapes other than sphere or flat in glass materials.
However, the injection-molding process makes it feasible and economical to produce more
sophisticated optical shapes such as asphere and diffractive surfaces in plastic provided a
mold is properly made. From the design point of view, the more sophisticated surface
shapes provide much better performance for many applications.
Unique designs possible: Many useful designs that cannot be realized with glass optics
can be achieved with plastic optics such as lens arrays and Fresnel lenses those are useful
for a range of light dispersion and collection applications.
Lightweight and shatter-resistant: The plastic materials are lighter weight and are more
shatter-resistant. This feature is very important for head-worn optics such as head-
mounted displays.

www.sunex.com 11/17/98
Page 2
Integral mounting: For most optical applications, the individual optical components must
be mounted in a system structure. With glass optics, it is done with separate mechanical
mounting hardware. However, with plastic optics, it is possible to include the mounting
features with the optical component. This not only reduces the overall system cost, but
also the improves the reproducibility of the assembly.
Consistent Quality: Plastic optics can be made with very consistent quality since all the
lenses are derived from the same mold cavity (ies). Modern statistical control techniques
are also been used to monitor the molding process to ensure a good yield is achieved.
The major drawbacks of plastic optics are mostly material related. For example, plastic
material is more sensitive to environment changes such as temperature and humidity. In
addition, the material flow pattern and shrinkage during molding also limit the surface
accuracy that is achievable with plastic optics. The index distribution within a molded
component may be inhomogeneous and varying with the polarization (birefringence). The
chemical properties of available plastic materials also limits the performance of the optical
coatings that can be deposited on the plastic materials. It is important for the optical
designer to understand the advantages as well as the limitations of plastic optics before a
decision is made to use plastic optics. We strongly suggest that you discuss with us before
finalizing your designs.
Processes
Design
Designing good plastic optics requires a solid understanding of the material properties and
the manufacturing processes. The advantages of plastic optics can be realized only when
the design is optimized for plastic manufacturing. The design rule for plastic optics is quite
different from that of the glass optics because of the significant differences in the material
and the manufacturing processes. Specific knowledge and design expertise are needed to
take full advantages of what precision plastic optics can offer.
Many existing designs are being converted to plastic designs. Successful conversions must
consider the performance and manufacturability of plastic optics. Merely substituting the
indices of refraction and re-optimizing the design are rarely sufficient to ensure good
manufacturability. Expert design assistance is to be sought at this stage.
Prototype
Once the design is completed, prototypes of plastic lenses can be made by diamond-
turning. This is a ultra-precision machining process that cuts the optical surface profiles
directly onto a solid block of plastic material. Experiences have shown that excellent
surface finishes can be obtained with low-index plastic materials. Higher index materials
such as polycarbonate do not yield very smooth surface finishes. This process is only
recommended for making a limited number of prototypes to verify the fit, form and
function of the design. The result of this process is not a validation of the

www.sunex.com 11/17/98
Page 3
manufacturability of the design because injection molded lenses will usually have very
different bulk index distribution and surface properties.
Pre-Production Stage
For most high volume products, a pre-production stage is required to validate the
manufacturing process. This can be done by constructing a single-cavity prototype mold
and developing a set of optimal molding conditions to process the part. Through this
prototype molding process, one can verify that design performance can indeed be achieved
with molded components. Design revisions if any should be implemented at this stage. In
many cases, the prototype molds can also be used to start limited production since
production tooling (multi-cavity) may take a significant amount of time to built and
qualify. Preliminary process capability can also be gained through this stage.
Production Stage
The production stage usually require the construction of multi-cavity production molds.
Depending on the product volume, throughput requirement and cost constraints, the
production tooling can have 2, 4, 8, or 16 cavities. In truly high volume cases, 32 cavity
molds can also be built to achieve the required throughput. The production molds are built
with quality steel, and are designed to function for at least several hundred of thousands of
injection cycles. Production tooling usually take significant amount of time to construct,
and are costly. Therefore, it is critical that the product has been truly finalized before the
production tooling is built.
Once the production molds are completed, it is necessary to qualify the molds. Process
capabilities can be established by sampling the production molds. Any iteration or
adjustment can then be made to achieve full potential of the production tooling. Molding
parameters are also critical here. During the mold qualification process, the optimal
molding conditions should be determined. These conditions must be maintained during
production in order to achieve capability of the process. SPC techniques are used to
monitor the production process to keep the process stable.
Coating
Unlike glass lenses, plastic lenses cannot be coated in an elevated temperature
environment. The coating materials must be deposited in room temperature condition.
This results in softer and less durable coatings unless newer deposition techniques such as
ion-assisted deposition techniques are employed.
Multi-layer dielectric coatings are routinely deposited on plastic components. For
example, a four layer anti-reflection coating can reduce the reflection to about 0.5% per
surface across the entire visible spectrum.
Assembly
Plastic optical assembly are usually done in a clean room environment to minimize the dust
and contamination. The components are designed to ensure ease of assembly. Snap-on

www.sunex.com 11/17/98

features are used whenever possible. UV-cementing, heat-staking and ultra-sonic welding
can also be employed if appropriate.
Since most optical tolerances are additive, it is important to design in testing points along
the manufacturing flow process to “kick” out non-conforming sub-assemblies before more
valued add-work is done to that part. Automatic in-line optical performance monitoring
such as MTF testing can be implemented to perform this function. SPC techniques should
be used here to ensure the process is not drifting out of the controllable range.
For high volume assembly, it is also possible to use semi-automated or fully automated
assembly machines to perform the optical assembly. These machines are built based on a
generic “pick and place” machine. In-line optical testing functions can also be integrated
with the assembly machine.
Component Cost
Even though plastic optics offers lowest cost in volume production, glass optics has cost-
advantages for small volume requirements from an overall cost point of view. The
following table compares the typical prices for glass and plastic optics at various volumes.

1 Overview 
Optical distortion is un-avoidable for ultra wide-angle and fisheye lenses. Sunex Dewarper Mini is a Adobe Photoshop compatible 
plug-in for processing distortion taken with Sunex miniature ultra wide-angle and fisheye lenses. It remaps the pixels such that the 
processed image is optimized for the intended application. This software is based on a new proprietary model developed by Sunex for 
real-world lenses. Unlike other distortion correction software, Dewarper Mini does not require that the lens follows the idealistic f-θ 
mapping. All distortion types can be modeled including our Tailored Distortion™ lenses. 
 
Key Features 
• Distortion cancellation: This feature compensates for the optically distortion in the lens. The resulting image is what one 
would see if the lens has zero optical distortion. If the horizontal field of view is greater than about 100 degrees, the off-axis 
objects may look stretched. This is caused purely by the fact that the lens is very close to objects, not the lens distortion itself. 
• Distortion tailoring: This feature allows one to optimize the amount of the distortion in the image. It can be used to simulate 
images taken with lenses having different amount of distortion (for example, our Tailored Distortion lenses). 
• One-shot panorama: This is a new projection method developed by Sunex for creating a 180° panorama from a single fisheye 
shot. This eliminates the process of stitching together multiple images. 
• Spherical and cylindrical panorama: This takes a circular fisheye image and expands it into spherical or cylindrical panoramic 
projections suitable for viewing with popular VR viewers such as Apple QuickTime. 
• 360 degree panorama: This is used to “unwrap” the 360 degree surrounding captured by a fisheye lens when it is pointing 
vertically. 
2 Installation 
Sunex Dewarper Mini is compatible with all image editors that accept Adobe Photoshop-compatible plug-ins such as follows: 
• Adobe Photoshop 7.0 and higher versions 
• Photoshop Elements 2 and higher versions 
• PaintShop Pro 7 and higher versions

Dewarper Mini v1.2 user guide 
Page 3 
The installation of the Dewarper Mini is simple. 
• Locate the plug-in folder for your program. Table 1 shows the typical directories used by popular programs 
 
Table 1 Typical plug-in directory 
Program Plug-in folder 
Adobe Photoshop C:\Program Files\Adobe\Photoshop\Plug-Ins\ 
Adobe Photoshop Elements C:\Program Files\Adobe\Photoshop Elements\Plug-
Ins\ 
Corel Paintshop Pro C:\Program Files\Paint Shop Pro\Plugins\ 
 
• Copy the “.8bf” file to plug-in folder of your program. 
• Open your image editor 
• Open a JPEG file or any 8-bit RGB files. 
• Dewarper Mini should now be accessible from the plug-in menu of your image editor under “Sunex”. 
3 Procedure 
The procedure for processing images is as follows: 
• Use your image editor to crop the image so that the horizontal width of the image matches the lens image circle. 
• Start the Dewarper Mini filter 
• Choose the Sunex lens used from the drop down box. 
• Choose the pixel pitch of the imager in µm in the drop down box. 
• Select an output image type from the drop down box. 
o Specify output parameters – the available options depend on the output image type selected. See next section for 
details. 
o If the “Transform X only” box is checked, the processing is only applied to the horizontal direction. 
• Click on the preview window to compare the image before and after processing. 
• Click on OK to process the full size image.

4 User Interface 
 
 
 
The user interface is straightforward and self-explanatory. The small preview window on the left shows the image in real-time as the 
output parameters are adjusted. Click anywhere within the preview window brings back the original image for quick comparison.

5 Examples 
5.1 Distortion Cancellation 
This compensates for the optical distortion in the lens. If the horizontal field of view is greater than about 100 degrees, the off-axis 
objects may look stretched. This is caused purely by the fact that the lens is very close to objects, not the lens distortion itself. 
Therefore, it is recommended that the horizontal field of view of the output image be kept <100 degrees.

5.2 Distortion Tailoring 
Choose this output to increase/decrease the amount of distortion in the image. First, select an output image horizontal field of view 
(HFOV). Then, use the “adjust distortion” slider to vary the amount of distortion. It is used for optimize the amount of distortion in a 
wide-angle shot, and to simulate the effect of a lens with different distortion. It achieves the effect of “field of view preserving 
zooming”.

5.3 One-Shot Panorama 
This is a new projection method for creating a one-shot panoramic image with 180° horizontal field of view (vertical FOV is cropped 
to 70°). No stitching of multiple images is required.

## Microsoft Word - Impact of Lens Chief Ray Angle on Image Quality.doc  [PDF]

Impact of Lens Chief Ray Angle on Image Quality 
By Alex Ning, PhD 
January 31, 2005 
1. Introduction 
Lens chief ray angle refers to the angle of incidence of an off-axis ray passing through the center of the 
lens stop on the image plane. If the imaging medium is a silver-halide film, the chief ray angle would 
not make too much difference to the final image quality because the film grain has isotropic angular 
response. However, if the imaging medium is a CCD or CMOS imager, the lens chief ray has 
significant impact on the final image quality. This is because the basic imaging element (a pixel) of 
CCD/CMOS imagers does not have isotropic response. This paper exams the effect of lens chief ray 
angle on the overall image quality. 
2. Experiment 
The Micron MT9D011 imager is used with two different lenses: Sunex PN DSL746 with a 1G2P 
structure and a competitor lens (also a 1G2P lens). Two lenses have the same f-stop of 2.8. The Sunex 
lens is designed to limit the max. chief ray angle within 20 degrees at the corner of the imager. The 
max. chief ray angle of the competitor lens is 25 degrees. An uniform white background is captured by 
using both lenses. The result is shown as follows. 
Sunex DSL746 Competitor Lens 
 
 
 
As can be seen from the above figure, the DSL746 lens has more uniform response in terms of color 
and corner brightness. The ratio of corner brightness to the center is known as “relative illumination”. 
It is also clear that the white balance (ratios between G, B and R) is more consistent from center to the 
corner with DSL746 lens. This difference can be explained in terms of chief ray angle mis-match with 
the sensor. At off-axis field angles, the higher chief ray angle of the competitor lens is outside the peak 
response region of pixel micro-lens. This results in a reduction in the overall response at off-axis angles. 
With color imager the higher chief ray angle can also cause cross-talk between adjacent pixels of 
different color. The cross-talk causes the ratios between R, G and B to vary from center to corners. A 
typical result is that the center will tend to be warmer, and corners cooler, as shown in the above figure.

Page 2 
3. Relative Illumination and Relative Color 
The above described phenomenon can be measured using many commercially available programs such 
as PhotoShop and Jasc Paint Shop Pro. We would first read out the pixel values for each R, G and B 
channel in the center of the image. These values will be used as baseline numbers. We will then read 
out the R, G and B pixel values at each of the four corners. Relative illumination (RI) can be computed 
as the ratio of corner luminance Y (=0.3*R+0.59*G+0.11*B) to the center luminance. The white 
balance is represented by the ratio of R to B. If R/B >1, the image is warm. If R/B<1, the image is 
cool. Relative color (RC) is represented by the corner R/B ratio divided by the center R/B ratio. 
 
 
 
Center-R/B=150/149=100.6% 
Corner-R/B=99/101=98% 
Relative Color(RC)=(Corner-R/B)/(Center-
R/B)=97.4% 
 
Center Y=0.3*R+0.59*G+0.11*B=149.89 
Corner Y=0.3*R+0.59*G+0.11*B=100.4 
Relative illumination (RI) = 67% 
Center-R/B=150/115=130.4% 
Corner-R/B=99/101=93.3% 
Relative Color(RC)=(Corner-R/B)/(Center-
R/B)=71.6% 
 
Center Y=0.3*R+0.59*G+0.11*B=134.94 
Corner Y=0.3*R+0.59*G+0.11*B=89.38 
Relative illumination (RI) = 66% 
 
4. Conclusion 
Mobile imaging modules demand very short profile lenses. The short profile lenses tend to have very 
high chief ray angles. The high chief ray angle can be detrimental to the image quality given the limited 
angular acceptance of the micro-lens array on the imager. This paper demonstrates that a 5 deg 
difference in the chief ray angle can cause a significant relative color issue (only 71.6% of the ideal 
goal) on the Micron 1.3MP imager. An acceptable relative color value should be >95% but less than 
105% for a good imaging system.

Optical Low Pass Filters Theory and Practice 
 
Summary 
In a high-quality, digital imaging system which uses CCD and CMOS sensors , an optical 
low pass filter (OLPF) is used to eliminate color Moiré fringes. It is important to note 
that Moiré fringes must b e removed passively in the optical system and cannot be 
removed by post -processing the image . See the difference in figure 1. The left side 
shows an image from an optical system without an OLPF, the right side shows and image 
with the same optical system with and OLPF. 
 
Figure 1. Left, without the OLPF; Right, with the OLPF 
 
Theory 
Since CCD and CMOS sensors sample image information at regularly -spaced, discrete 
points called pixels each sensor has a frequency limit, called the Nyquist frequency , that 
is defined by the geometry of its pixels. This frequency is equal to the inverse of the two 
times the pixel pitch. If the lens passes spatial frequency that is greater than the Nyquist 
frequency of the sensor, it cannot be resolved by the sensor . Worse, s patial frequencies 
that are greater than the Nyquist frequency will cause aliasing artifacts . These 
phenomena are often observed as colorful fringes called Moiré fringes, on the image. 
 
An OLPF placed between the lens and the image sensor stops the optica l system from 
passing spatial frequencies greater than the Nyquist frequency of the sensor. The filter 
cuts the high frequency information and passes only the low frequency information, 
removing the Moiré fringes from the image. 
 
OLPFs are made of several layers of birefringent optical crystals cemented together. The 
number of layers and thickness of each layer is defined by the pixel spacing of the sensor

2 
and the application. It follows that each OLPF design must be tuned to a particular 
sensor and application. 
 
For color imaging, an IR cut -off function is often in tegrated into OLPF as well. A 
reflective IR cut-off coating can be applied to an external surface or an absorptive IR cut-
off filter layer can be added to the quartz layers. 
 
Practice 
• When installing the OLPF into the digital imaging system it must be placed be tween 
the lens and the sensor. The performance is dictated by the layer th ickness and any 
optical coatings on the external surfaces . The exact location along this z -axis does 
not affect the performance of the filter significantly. 
 
• We do not recommend affixing the low pass filter to the sensor cover glass or use it as 
a sensor cover glass! Due to surface quality imperfections it is recommended that the 
filter be place more than 1mm (>1mm) away from the sensor plane. No matter how 
tight the surface quality specification there are always scratches and digs on the order 
of the pixel size that will show up in the image as blobs or dust if the filter is too close 
to the sensor plane. 
 
• The x-axis and y-axis [length and width] orientation of the OLPF with respect to the 
sensor is important. For a 4:3 and 16:9 aspect ration sensors, ensure that the long 
edge of the filter is square with the long edge of the sensor. 
 
• The filter will function if the IR cut coating faces the sensor or faces away from the 
sensor. The optical performance is the same.

Lateral Color in Mobile Imaging Lenses 
By Alex Ning, PhD 
January 21, 2005 
1. Background 
Chromatic aberration (CA) is one of several aberrations that degrade lens performance. Other common 
aberrations include coma, astigmatism, and curvature of field. Chromatic aberration occurs because the 
index of refraction of the lens material varies with the wavelength of light, i.e. it bends different colors 
by different amounts as shown in Figure 1. This phenomenon is called dispersion. Minimizing 
chromatic aberration is one the goals of lens design and it is accomplished by combining glass elements 
with different dispersion properties. Three element lenses (3P or 1G2P) are popular for mobile imaging 
applications. However, the optical performance of all 3-element lenses is limited by lateral chromatic 
aberration, also known as lateral color. This aberration can only be eliminated using a 4-element design 
with a 2P2G configuration. This paper compares the lateral color of a 1G2P lens with a 2G2P lens.

2. How to detect lateral color 
The two types of chromatic aberration are illustrated in Figure 1. 
• Longitudinal chromatic aberration causes different wavelengths to focus on different image 
planes. It causes degradation of MTF response – with different amounts for different colors. 
• Lateral chromatic aberration is the color fringing that occurs because the magnification of the 
image differs with wavelength. It tends to be far more visible than longitudinal CA. For a 
given amount of lens CA, the smaller the pixel size the more visible the lateral CA in the 
captured image. The lateral CA can measured in terms of number of pixels. In a good 
imaging system the lateral CA should be <1x pixel. 
The lateral color is most visible if one examines a black/white edge at an off-axis viewing angle. The 
black/white edge should be oriented almost perpendicular to the radius. For example, following is the

using a Micron 2MP (1600x1200) demo board with 2.8 µm pixel pitch. 
 
 
With a 2P2G design (Sunex PN DSL871/872) the lateral color is eliminated. As a result, the optical 
resolution is increased.

3. Measurement of Lateral Color 
The amount of lateral color can be measured using commercially available software (ImaTest at 
http://www.imatest.com/). This program examines the transition from black to white at an off-axis edge 
for each primary color, and then calculates the amount of chromatic aberration at that edge.

The blue channel transition (the blue color curve) 
occurs before the red channel (red color curve). 
The distance between the two curves at 50% edge 
response is 2.1 pixels. This represents 0.468% of 
the distance to the center of the picture. This implies 
that there is 0.468% difference in magnification 
between the blue and red channel in this lens. 
 
The blue channel transition occurs at nearly the same 
location as the red and green channels. This results in 
very little chromatic aberration. The separation 
between the blue and red is insignificant (0.171 pixel) 
in comparison to the size of the pixel. 
 
 
4. Conclusion 
With the industry trend towards higher pixel count image sensors with smaller pixel sizes the lateral 
chromatic aberration of a 3-element lens will become a major problem. For the Micron 2M imager 
(MI2010) with a 3-element lens, the lateral color can be 2 or more pixels. Aberration on this order 
significantly reduces the optical resolution and MTF at off-axis viewing angles resulting in an apparent 
decrease in image detail. 
 
For next generation mobile imagers with higher resolution and smaller pixel spacing more sophisticated 
lens designs, such as the Sunex DSL871 and DSL872 with a 2G2P structure, are required to eliminate 
the lateral color. These 4-element lens designs allow the end-user to take full advantage of the increased 
imager resolution.
