Ar Coating Sapphire Glass Crystal Semiconductor Wafer

Sapphire windows sapphire glass crystal sapphire optical glass window ar coating

Sapphire Windows are manufactured from single crystal sapphire, making them ideal for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Sapphire is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3) and is useful in a transmission range from 0.2 - 5.5μm.
 

1. Sapphire Introduce on advantagement

1. Electric insulation ,it is 10000 times of usual glass,30 times of the ceramic,

   and 150 times of stainless steel .

2. high temperature resistant, Sapphire Round / Rectangular Optical Window can work

   under 1200°C continuously,and in short time can even work under 1450°C,
   its softening temperature is 1650°C,and the melting temperature is 1750-1800°C.

3. Excellent thermal shock stability

4. Corrosion resistant, Except hydrofluoric acid, Quartz Plate Of Optical Grade do not

react with any acid and base except hydrofluoric acid.
5. Excellent thermal shock stability
6. High transmission to 85%
7. Hardness up to 9.0
