Performance
● Pentagonal prism is one of the redirectors for beam angle setting (90°). It serves two purposes: first, whatever
the angle of incidence on the first surface is, the outgoing light will turn the incident light to a certain angle (90°);
second, unlike a right-angle prism, the imaging has neither rotation nor specular reflection.
● Such prism is used for camera viewfinder. Pentagonal prism is most suitable for image observation systems or
measuring instruments.
