Right Angle Prism

Right angle prism
right angle prism may be used as a 90 degree reflector or 180 degree retroreflector. The prism deflect, deviate and rotate beams of light as well as dispersing their wavelengths. They usually used for beam deviation or as substrates for beam splitters. We also provide other optical prism such as roof prism.
