Right Angle Prisms
Right-angle prism is the most common type of prisms. It is used to re-direct a beam of light at 90 degrees from the the incident direction or used as a 180 beam retro-reflector. They are often coated with various optical coatings to form cubic beam splitters and color separation cubes used in various projection systems.

Right Angle Prisms,Uncoated
- Total internal reflection prisms
- 90°or 180°beam deflection
Right Angle Bending,Prisms
Right angle bending prisms are anti-reflection coated on the legs. Optionally, the hypotenuse may be coated with second-surface aluminum protected by black paint to ensure grazing incidence reflection. These prisms are suitable for optical delay lines and for high power use
Right Angle Folding Prisms
- 180°reflectors
- Aluminum on legs and AR on hypotenuse
Folding prisms are intended for use as 180°reflectors. An anti-reflection coating is applied to the hypotenuse. Second-surface aluminum protected by black sealing paint is applied to the legs to ensure grazing incidence reflection. These prisms are suitable for optical delay lines and for high power use
