Quartz Glass
The quartz glass is a monocomponent molten glass that fused by SiO2, it has high transmission in the range of the UV, the visible light, the near-infrared light, as well as the high temperature resistance, the corrosion resistance. It is essential optical material for the highly stabilized optical systems under varying environmental conditions. With the professional production and development skills, SIKOTY can make optical components, prisms, lenses, and so on, which vary in shape and size, to meet our customer's requirement in regard to the technology. We have experience and technology in making special-purpose quartz glass for National projects. we can make big size quartz glass plate according to the customer’s special request.
