Application of optical coating machine

Now mobile phone is an inseparable tool for people. In the field of mobile phone, in addition to imaging quality, lens transmittance plays a very important role in improving image quality.At present, the mobile phone industry usually uses resin as the lens base material. In order to reduce the mirror reflection and improve the transmittance, we will coat AR antireflection film (antireflection film) on the lens surface. It is a kind of hard heat-resistant oxide film, which can minimize the reflectivity of the surface of components within a specific wavelength range.Without coating, each surface of optical element will produce about 4% energy loss due to reflection, while AR antireflection coating requires GX2050 ZHENHUA optical coating machine.

There are various kinds of doors and windows glass itself, in recent years, various sunscreen glass, self-cleaning glass, thermal insulation glass, radiation protection glass, etc. have gradually entered the consumer's sight.


In fact, these products are not so mysterious. These special functions of glass are coated by the coating process, and there are many ways of coating. Some glasses have been coated before leaving the factory, and some are coated by the glass coating solution later. , Can achieve very good results.


Coated glass, borrowed from Baidu Encyclopedia's introduction is: Coated glass (Coated glass) is also called reflective glass. Coated glass is to coat one or more layers of metal, alloy or metal compound films on the glass surface to change the optical properties of the glass and meet certain requirements. According to the different characteristics of products, coated glass can be divided into the following categories: heat reflective glass, low-e glass (Low-E), conductive film glass, etc.
