A minute to learn about sapphire window pieces！

What is sapphire window piece?
Sapphire window piece is a transparent window made of synthetic sapphire material. Sapphire is a gem-grade aluminum oxide with a high degree of transparency and hardness. It usually appears dark blue or transparent in color, and has a unique flash effect in light. 

Features of sapphire window?
High strength surface hardness
Good heat conduction, infrared penetration
Scratch resistant, high temperature resistant
Chemically inert, acid and alkaline resistant
With excellent surface hardness, the transmittance extends from the ultraviolet to the mid-infrared wavelength region. Sapphire window pieces can only be scratched by a few substances other than it. The substrate is chemically inert and insoluble in water, common acids or bases at temperatures up to about 1000°C.

So where is it used?
Sapphire window pieces are widely used in industrial and scientific fields. Due to its high hardness and wear resistance, sapphire is used as a window and viewing window in high pressure and high temperature environments. It is also used as a window material in lasers, optical instruments and sensors. Sapphire window pieces have excellent optical properties and can transmit most of the visible and infrared spectra, so they are also widely used in optics and optical communication equipment.
