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.
