What are the application fields of optical films-film suppliers

What is an optical film? An optical film is composed of a thin layered medium, a type of optical medium material that propagates light beams through the interface. The application of optical films began in the 1930s and has now been widely used in the fields of optics and optoelectronics to manufacture various optical instruments. The principle of optical film The principle of optical film is to coat or coat one or more dielectric films or metal films or a combination of these two types of films on optical elements or independent substrates to change the transmission characteristics of light waves. Including light transmission, reflection, absorption, scattering, polarization and phase change. Optical film is ubiquitous in our lives. From precision optical equipment, display equipment, to glasses, digital cameras, various household appliances in daily life, or anti-counterfeiting technology on banknotes, all can be called optical film technology Application extension. If there is no optical film technology as the basis for development, modern optoelectronics, communications or laser technology will not be able to make progress.
