Commercial Grade Penta Prisms
Commercial Grade Penta Prisms
Product name : Commercial Grade Penta Prisms
Description :
Penta prisms are five-sided prisms featuring a ray deviation of 90° and a right handed image. The reflecting surfaces are aluminized for increased efficiency. Slight movement of the prism does not affect the true right angle at which light rays are reflected, making a penta prism the ideal optical tool for defining a right angle in an optical system.
