Vacuum coating equipment optical film classification and application

Vacuum coating equipment optical film, the surface is smooth, the interface between the film layers is geometrically divided; the refractive index of the film layer can change at the interface, but it is continuous within the film layer; it can be a transparent medium or absorption Medium; can be uniformly normal or non-uniformly normal. The actual applied film is much more complicated than the ideal film. This is because: during preparation, the optical and physical properties of the film deviate from the bulk material, and the surface and interface are rough, resulting in diffuse reflection of the beam; the mutual penetration between the film layers forms a diffusion interface; due to the growth of the film , Structure, stress and other reasons, forming various anisotropy of the film; the film layer has a complex time effect.

Vacuum coating machine, vacuum coating equipment optical film can be divided into: reflective film, anti-reflection film / anti-reflection film, filter, polarizer / polarizer film, compensation film / phase difference plate, alignment Film, diffusion film / sheet, brightness enhancement film / prism sheet / condenser sheet, shading film / black and white glue, etc. Related types of derivatives include optical grade protective films and window films.

Vacuum coating machines, vacuum coating equipment and optical films are ubiquitous in our lives, from precision and optical equipment, display equipment to optical film applications in daily life; for example, glasses, digital cameras, and various household appliances that are usually worn , Or anti-counterfeiting technology on banknotes, can be called an extension of the application of optical film technology. 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, which also shows the importance of research and development of optical film technology.
