[0002] A prism is a transparent object surrounded by two intersecting but non-parallel planes, used to split or disperse light beams. A prism is a polyhedron made of transparent materials (such as glass, crystal, etc.), which is widely used in optical instruments. Prisms can be divided into several types according to their properties and uses. For example, in spectral instruments, the "dispersion prism" that decomposes composite light into a spectrum is more commonly an equilateral prism; in instruments such as periscopes and binoculars, the "total reflection prism" that changes the direction of light and thus adjusts its imaging position is generally a right-angle prism. In modern life, prisms are widely used in digital devices, science and technology, medical instruments and other fields.

[0003] When the existing prism is polished, it is usually installed through a specific mold and then polished. Since the sizes of the prisms to be produced are different, multiple different types of prism fixing molds are required, which is troublesome to use. Utility Model Content
