Silicon oxide is a low refractive index material. Its melting point is close to
It is the basic material which commonly used in optical thin-film coating.
It is wildly used due to its superior electrical insulation and feasibility in many industries— include optical lenses and optical filters…etc.There are many types of quartz materials used for coating, such as granule, tablet, and ring-shaped, depending on the type of process or experiment requirements. Quartz ring can be used in optical coating and semiconductor process. It has high purity, high light transmission and good adhesion. It can be applied to low-refractive materials of optical coating, and coated with high-refractive-index materials through coating equipment on optical glass. Commonly used quartz ring specifications are divided into large rings and small rings, the appearance is opaque frosted surface, no bubbles and black spots.
