The application of optical thin films is very extensive, ranging from glasses, camera lenses, mobile phone cameras, LCD screens for mobile phones, computers, and televisions, LED lighting, biometric devices, to energy-saving windows in automobiles and buildings, as well as medical instruments, testing equipment, optical communication equipment, etc., especially in the fields of national defense, communication, aviation, aerospace, electronic industry, optical industry, and so on.

Optical thin films can be used to obtain various optical features:

1) Surface reflection can be reduced to increase the transmittance and contrast of optical systems, such as the antireflective spherical mirror in optical lenses.

2) Surface reflection can be increased to reduce light loss, such as mirrors in laser gyro navigation systems for aircraft and missiles.

3) High transmission and low reflection can be achieved in one band, while low transmission and high reflection can be achieved in adjacent bands to achieve color separation, such as the color separation mirror in liquid crystal displays.

4) It can achieve high transmittance in a very narrow band and low transmittance in other bands, such as narrow-band pass filters used in automatic driverless vehicle technology or radar on unmanned aerial vehicles, and narrow-band pass filters required for structured light face recognition. The applications of optical thin films are countless and have penetrated into every aspect of life.
