Optical wizards are free online tools (registration
required) for assisting the selection of the proper optics for your
- Find a lens by imager
specification: Given the imager resolution and pixel
pitch, this tool will compute a list of imager key
characteristics, and search our database for all matching lenses. It
also calculates the field of view of each lens including the impact
of distortion on the specified imager.
- Field of view and EFL calculator:
This tool will calculate the required lens effective focal length to
achieve a desired field of view in degree or vice versa. This tool will
work for all lenses including wide-angle and fisheye lenses with
significant amount of distortion.
- Depth of field calculator: This
tool will calculate the depth of field and hyper-focal distance for
a given lens focal length and f/#
. It requires user to enter
the maximum blur size in µm. It works for both infinite
and finite conjugate systems.
- Imaging optics solver: For a given
object and image size requirement, this tool calculates the
required focal length of the lens based on first order optics. It then recommends a suitable
lens structure and focal length based on the object field size. It
is a good starting point for solving finite conjugate problems.
- Lens element designer: This
wizard designs lens element based on functional requirement. This is
used to design a custom lens element if an off-the-shelf element
does not meet your need.
- Search imager database: We have
built database of popular CMOS imagers from major suppliers. You can
search for an imager based on manufacturer's name, PN and imager
resolution. Once an imager is identified, you can then go on
to search for a list of compatible lenses.
- Search lens by optical
parameters: This is a collection of advanced search tools.
