Description of Micro prism

Micro prisms provide an effective way to change the path of a beam within a component or fiber device. When light passes through a face of a prism, it is refracted. The main use of microprisms in optical fibers is to direct light beams from one optical channel to another with high accuracy. It has all the optical properties of prisms. It's just a very small size.

Due to the small size of the microprism, its processing method is slightly different from that of ordinary prism. It is also made by cutting, grinding and polishing optical glass.
