In optics 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. The traditional geometric shape is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" generally refers to this type. Some types of optical prisms do not have the shape of geometric prisms. The prisms can be made of any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, plastic and fluorite. A dispersive prism can be used to divide the light into its constituent spectral colours (the colors of the rainbow). In addition, prisms can be used to reflect light or to divide light into components with different polarisations.
