:

Penta prisms deviate beams by 90 degrees. The deviation is independent of prism orientation. Due to geometry, the reflecting surfaces must be coated with a reflective coating.

• Image is neither inverted nor reversed as it is deviated by 90 degrees.
• 90-degree deviation angle applies to all rays transmitted by the useful aperture, regardless of the angles between these rays and the optical axis (or entrance and exit face normals).
• Antireflection coatings are available for entrance and exit faces.
