  • optical pentaprism CVI Melles Griot
Penta prisms deviate beams by 90 degrees. The deviation is independent of prism orientation. CVI Melles Griot supplies prisms with two levels of deviation tolerance. Because of geometry, the reflecting surfaces must be coated with a metallic or MAX-R coating. Penta prisms come standard with a protected aluminum coating.


* Image is neither inverted nor reversed as it is deviated by 90 degrees.
* The 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.
