Sapphire window is one of the most hardest optical window in the world. It was widely used as Sight Windows / Lens Cover/ Viewport Windows / Laser Windows / Sports Equipment / Touch Screen to protect precision sensors , screen plant and people from harsh conditions and situations.

Sapphire is a form of alumina (commonly known as alumina (α-alumina) or alumina) and is one of the most abundant compounds in nature. Naturally, alumina (Al2O3) is a white powdered material widely used as an industrial abrasive. When heated to approximately 2050 degrees ℃(nearly 4000 degrees F°), the powder melts and a single crystal can then be formed using any of several crystal growth methods. We are using Kyropoulos Sapphire(KY Sapphire).

Thanks to Sapphire’s superior hardness specification(Moh’s 9 ), it almost can’t be scratched by any natural materials but be only ground by diamond(Moh’s 10). This means it allows use your equipment with sapphire window in any harsh working conditions without extra protection for them.

As an ideal optical window material, of course it must be very good in light transmission performance, Sapphire crystal has good light transmission performance, and its light transmission range is 0.15~7.5 microns, covering ultraviolet, visible, near-infrared, mid-infrared and other wavebands. In most applications, the surface of the sapphire window is not coated for use, , coating will make the surface scratched easily.

Besides the outstanding hardness, sapphire also have plenty advantages. Here we list some Basic-Properties for your inference:

1.Maximum Useful Temperature ≈2000°C

2.Transmission Rate Of Visible Light: Around 90% ( Uncoated )

3.Only Attacked By Boiling Hydrofluoric Acid.
