What is an optical film? What are the application levels (two)-film suppliers

The characteristics of the optical film are: the surface is smooth, the interface between the film layers is geometrically divided; the refractive index of the film layer can jump at the interface, but it is continuous in the film layer; it can be a transparent medium or an optical Film absorbing medium; it can be uniform in the normal direction or non-uniform in the normal direction. The actual film is much more complicated than the ideal film. This is because: when the film is prepared, the optical and physical properties of the film deviate from the bulk material, and its surface and interface are rough, which leads to the diffuse scattering of the light beam; the interpenetration between the film layers forms a diffusion interface; due to the growth of the film layer , Structure, stress and other reasons, the anisotropy of the film is formed; the film has a complicated time effect. Optical film is divided into reflective film, antireflection film, and filter film according to application.
