Penta Prisms
Penta prism can deviate an incident beam without inverting or reversing to 90°.The deviation angle of 90° is independent of any rotation of the prism about an axis parallel to the line of intersection of the two reflecting faces. It is commonly used in Plumb Level, Surveying, Alignment, Range finding and Optical Tooling. The reflecting surfaces of this Prism must be coated with a metallic or dielectric coating. The standard Penta Prism reflecting surfaces are coated with aluminum or enhanced aluminum.

By adding a wedge and with partial reflective coating on first reflective surface,Penta Prism can be used as Beamsplitter.We supply Beamsplitter Penta Prism with standard Transmission/reflection (T/R) ratio of 20/80,50/50.Other T/R ratio is available upon request.
