Prism, Optical
a body made of materials transparent to optical radiation (light) in some frequency or wavelength band and bounded by plane surfaces. An optical prism is not necessarily a strictly geometrical prism. Optical prisms are subdivided into three broad classes, which are sharply distinguished according to function: spectroscopic or dispersing prisms, reflecting prisms, and polarizing prisms.
