What is an optical film? What are the application levels (1)-film suppliers

The main optical thin film devices include reflective film, anti-reflection film, polarizing film, interference filter, beam splitter and so on. They have been widely used in the national economy and national defense construction, and have received increasing attention from scientific and technological workers. For example, the use of anti-reflection film can reduce the luminous flux loss of complex optical lenses ten times; the use of high reflectance mirrors can double the output power of lasers; the use of optical films can improve the efficiency and stability of silicon photocells sex. The simplest optical film model is a thin layer of a homogeneous medium with a smooth and isotropic surface. In this case, the optical interference theory can be used to study the optical properties of optical films. When a monochromatic plane wave is incident on the optical film, multiple reflections and refractions occur on its two surfaces. The directions of the reflected light and refracted light are given by the law of reflection and refraction, and the amplitude of the reflected light and refracted light The size is determined by the Fresnel formula (see the refraction and reflection of light on the interface).
