Antireflection coating, also known as antireflective coating or ar antireflection glass (antireflective glass or antireflective glass), is a kind of coated glass which is specially treated on the surface of glass to improve the transmittance of glass. It is deposited on the surface of optical elements to reduce surface reflection and increase the transmittance of optical system

The working wave band can be divided into single wavelength, multi wavelength and wide band antireflection coatings according to the working wave band range, but the most widely used antireflective coating in visible light band. The function of light visible antireflection coating is to reduce the intensity of reflected light, thus increasing the intensity of transmitted light and making the optical system imaging clearer. The principle is to use the interference effect of different optical materials to eliminate the incident light and reflected light, so as to improve the transmittance.

Appropriate film deposition process is an indispensable condition to improve the film quality and production capacity. From the perspective of film technology, HCVAC has developed and produced a vacuum coating system suitable for optical applications. In order to provide corresponding customer solutions, we use our experience in coating process development to make the components meet the requirements of process technology. Therefore, we have the model A wide range of coating systems.
