Optical coating equipment for film coating system

Optical coating equipment for film coating system

In the optical coating, it is often nothing more than a contact glass, optical aerospace industry for relatively scarce material through the optical film coating system to achieve the effect of a specific function which is the value of the film exists.
The film refractive index mainly to reduce or eliminate reflected light lenses, prisms and other optical surface, the optical element, in order toreduce light reflection loss element, in which a transparent dielectric film surface coating system, known as an anti-reflection or antireflection film, antireflection coating effect is closely related to the refractive index of the film thickness.
Transmittance and optical coating film refractive index-related, then the thickness of the film there is no relationship? In many complex optical systems, inhibition of the emitted light is very important, relatively speaking, the color of the emitted light more advanced optical system will be more and more, after the experiment, the film thickness to substantially affect light transmission is relatively small, if the thickness of the film something down, you will find the emitted light and reflected light a B exist nc * 2D optical path difference.
Optical coating machine such equipment is made of optical film coating tools in the course of several decades of development, realized at low temperature and high temperature coating system wavelength stabilization of high-quality film, the automated control system, simply adjust parameters, the entire coating process is completely grasp by machine, reducing the uncertainty.
A widely used system for all kinds of precision optical film coating, electrical membrane, such as laser mirrors, cold film, beam splitter, antireflective coatings, resin lenses, various filters, sun protection film, silicon and metal coating film optical coating machine.
A widely used in electronic products AR coating system protective film, bandpass filter, a dichroic mirror, to enhance the reflective film, laser mirrors, ITO film, a motor with a metal film, a polarization sub-prime and other electronic products optical coating machine.
