Penta Prism

For penta prism, the deviation angle of 90 is independent of the orientation of the prism, thus it is particularly important and wide in application which the prism orientation cannot be precisely controlled. TEMTO can supply high dimension and angle contorl penta prism. The coating or painting is designed bu customer according to it is detailed application.

It is widely used in projection optical systems, imaging optical systems, optical measurement and display systems.
