40/20 Polished Right Angle Glass Triangular Prism for Sale
40/20 polished right angle glass triangular prism for sale
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.
