A prism is a transparent optical element with flat, polished surfaces that refract light. At least two of the flat surfaces must have an angle between them. The exact angles between the surfaces depend on the application,prism: In optics, piece of glass or other transparent material cut with precise angles and plane faces, useful for analyzing and reflecting light.
Dispersive prism can be used to break light up into it's constituent spectral colors(the color of the rainbow).Furthermore, prisms can be used to reflect light or to split light into components with different polarizations.
Optical Prism include Right angle prism.Equilateral dispersing prism.Dove Prism.Corner Cube Reflectors.Beamsplitter, Powell prism, dove prism, wedge prism, penta prism etc.
