Silica optical coating material is the essential material in the production of optical lenses and other optical components.

Silica optical coating material is the essential material in the production of optical lenses and other optical components. It is used when a firmer coating is required. Having less stress and easy to form films, it is also widely used in optical filter production. Especially in recent years, with the rapid development of optical communications, when optical filter with hundreds of layers are required (dense wavelength division multiplexing devices), no other material can be better than Sio2 coating. At the same time, being a very good electrical insulating material, silica optical coating materials are also used in large-scale and ultra large scale integrated circuits.

Because of its high hardness, it is used in surface protection as well. .

In our company, we use only high purity silicon dioxide powders as raw materials. Some appropriate useful elements are also added to effectively control the hazardous substances in silica. We smelt the raw materials under temperatures as high as 2000. Silica optical coating materials are produced by precisely grinding after fine annealing.

Our products have very high and stable success rate in coating. It is the most advanced specific product, which has been competitive among Japanese and German optical companies.  Our products are mainly used in lens and prisms for digital cameras, projectors, photo-copiers, microscopes, and advanced telescopes, and optical filters of optical test equipments and optical communication equipments.
