The cause of the lens coating and methods

Lens coating, lens, or glass lenses, lamp lens are need coating appearance. Lens coating in fact, the reason is very simple, because the object has reflection effect on the light, because a lot of problems on the lens on the combination of the lens is impossible to let all light completely through various angles in theory, the light transmittance can reach more than 90%, the remaining 10% will be reflected out, form a glare. So you need to coating.
Lens coating in 1968 a new generation of coating technologies have been developed, coating process can be cheap and standard, coating lens is becoming more and more popular. Lens coating method, there are many on the market at present the most widely as one of the most popular coating method, physical vacuum coating method.
The latest way of physical coating technology, such as vacuum vapor deposition, ion plating a variety of different forms. The coating strength and uniformity generally higher than that of chemical coating. The past chemical coating, relative pollution is big, can't multilayer film plating. The latest vacuum coating to replace the chemical coating.
General coating layer on the surface of the lens itself is colorless, transparent, not only through the lens of the light will be reflected back, reflective visible to form the human eyes. Coating lens, the lens of the light transmittance is lower, reflections on the surface of the lens is more serious, therefore, each different camera lens, must according to the material used in the lens and the degree of absorption of different colours, plating on the different characteristics of the coating, mutual collocation, can increase the light transmittance of lens combined, and make the lens of light transmittance equilibrium.
