Optical prism Sunex

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.

High transmission can be achieved, using the hypotenuse face in total internal reflection (TIR), with an antireflection coating on the entrance and exit faces.
The prism can be used as an internal or external mirror by applying a metallic coating on the hypotenuse.
We also offer fused silica prisms, and precision grade and ultra-precision grade glass prisms with tighter manufacturing tolerances.
