Optical coating machine
In the optical coating, the glass is often contacted. The optical aerospace industry is relatively rare. The material is coated with an optical film layer to achieve a specific functional effect. This is the value of the film layer.
The refractive index of the film layer is mainly to reduce or eliminate the reflected light of optical surfaces such as lenses and prisms. In the optical element, in order to reduce the light reflection loss of the element, a transparent dielectric film layer is plated on the surface, which is called anti-reflection or anti-reverse. The effect of the film and the antireflection film is closely related to the refractive index and thickness of the film.

Film emissivity = [(n2-n1) / (n1 + n2)] * 2
The transmittance of the optical coating is related to the refractive index of the film, so is it related to the thickness of the film? In many complex optical systems, the suppression of emitted light is very important. Relatively speaking, the more advanced optical systems emit more light, the experimentally, the thickness of the film is basically compared to the transmittance. Small, if you work hard on the thickness of the film layer, you will find that the emitted light A and the reflected light B have an optical path difference of nc*2D.

Optical coating machine is a tool for coating optical film. In the course of decades of development, it has achieved high-quality film with stable wavelength at low temperature and high temperature. In the automatic control system, it only needs to be adjusted. Parameters, the entire coating process is completely controlled by the machine, reducing uncertainty.
