Sapphire window piece supplied

Sapphire window piece

The window sheet is a biplanar optical glass, usually used as a protective window for sensors and jiance devices. The window slice does not change the magnification of the system. Substrate materials include various optical glass, K9, UV fused quartz, fused quartz and calcium fluoride (CaF2), magnesium fluoride (MgF2), zinc selenide (ZnSe), germanium (Ge), silicon (Si) and other materials.

Ruiyan Optical provides window film coating services, anti-reflection film, high reflective film, spectroscopic film, metal film and other optical coating. The wideband antireflection film can be used in ultraviolet, visible, near infrared and mid-infrared bands.

Uncoated sapphire has excellent surface hardness and a transmittance range from ultraviolet to mid-infrared wavelength region. Sapphires can only be scratched by a few other substances. The uncoated substrate is chemically inert and insoluble in water, common acids or bases at temperatures up to about 1000°C.

Sapphire has high temperature resistance, good thermal conductivity, high hardness, infrared permeability and good chemical stability. It is widely used in many fields of industry, national defense and scientific research (such as high-temperature resistant infrared window, etc.). High precision sapphire substrate

Sapphire crystal - hard oxide crystal, is the basic single crystal form of alumina (Al2O3). It has high strength, high hardness, high temperature resistance, friction resistance, corrosion resistance, good light transmission performance, electrical insulator. Sapphire is second only to diamond in hardness.

Sapphire crystals produced by the company are very hard, with a Mohs hardness of 9, second only to hard diamond. It has excellent light transmission, thermal conductivity and electrical insulation,

Mechanical properties, and has the characteristics of wear and wind erosion resistance. The melting point of sapphire crystal is 2050℃, the boiling point is 3500℃, and the high working temperature is up to

1900 ℃. Therefore, as an important technical crystal, sapphire has been widely used in many fields of science and technology, national defense and civil industry.
