Fused Silica Equilateral Triangular Prisms Angles

An optical prism is a transparent optical element with flat, polished surfaces that refract light. At least one surface must be angled—elements with two parallel surfaces are not prisms. The traditional geometrical shape of an optical prism is that of a triangular prism with a triangular base and rectangular sides, and in colloquial use "prism" usually refers to this type. Some types of optical prism are not in fact in the shape of geometric prisms. Prisms can be made from any material that is transparent to the wavelengths for which they are designed. Typical materials include glass, plastic, and fluorite.

Prisms may be used in an optical system so that the exit beam may be reflected from the entrance direction.The images produced by prisms can be made inverted or rotated.

Equilateral prisms has three equal 60°angles, and are mostly used to disperse the spectrum.
