Silica introduction:

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 materdials are also used in large-scale and ultra large scale integrated circuits.
