Optical Prisms

Prism, a transparent object surrounded by two intersecting planes that are not parallel to each other, used for splitting or dispersing light beams. Prism is a polyhedron made of transparent materials (such as glass, crystal, etc.). It is widely used in optical instruments. Prisms can be divided into several types according to their properties and applications. For example, in spectral instruments, the "dispersion prism" that decomposes the composite light into spectrum is more commonly used as equilateral prism; In periscope, binocular telescope and other instruments, changing the direction of light to adjust its imaging position is called "total reflection prism", which generally adopts Right Angle Prism.
