Sapphire Optical Window, Double Convex Lens, UV Grade Sapphire Plano Convex Lens

Specification

As a transparent physical barrier, windows enable light to enter a different environment from one environment. For example, from air to water, or from vacuum to air. Such as different temperature, pressure, chemical composition or cleanness.

The hardness of sapphire is only lower to diamond and it is hard to scratch. Its transmission wavelength ranges from deep ultraviolet to infrared. At present, sapphire is a kind of material widely used, which has the properties of scratch resistance, impact resistance and flexibility. Sapphire has long been used to make watch protective glass or camera lens protective glass cover and filter glass, and now it is widely used to make mobile phone screen. Sapphire glass is composed of colorless synthetic corundum (a mineral produced by alumina AL2O3). In fact, strictly speaking, sapphire is not a kind of glass, because it does not have glass amorphous structure, but a crystal structure.

Sapphire window products can be used as Gan, GaAs and other new materials, integrated circuit substrates, epitaxial and directional substrates, watch glass lens, optical lenses and surface acoustic wave devices; Because sapphire has good light transmittance, its infrared transmittance almost does not change with temperature, so it can be used as infrared window, high temperature furnace observation window, counter window, etc. It ranges from ellipse, oblique disc, step window, oblique disc and so on.

Sapphire has a good light transmittance, and the infrared transmittance almost does not change with temperature, high temperature resistance, which makes it possible to use artificial sapphire window in high pressure chamber for spectroscopic analysis. Therefore, sapphire crystal materials of Czochralski method are commonly used to make various infrared and ultraviolet windows and lenses, high temperature observation windows, laser windows, etc., which are the key components for manufacturing infrared analyzer, night vision instrument, guidance instrument, laser beauty instrument, bar code reader, sapphire pressure sensor, high temperature and low temperature observation windows.
