The optical spectroscope is also known as the splitter, half through half mirror. It is an important part of the optical interferometer, which is widely used in laser equipment, optical fiber communication system and other fields. The characteristic of the spectroscope is an optical device that can divide a beam of light into two (or more) beams. After separation, the properties of each beam of light are exactly the same as that of the light source, and the sum of the light intensity of each beam is equal to the light intensity of the light source, which can achieve 50% of the light penetration, and the other 50% of the light is reflected off, which is evaporated by multilayer film, non-metallic film, so its absorption rate is very low .
