Product Details
semiconductor sapphire wafer by customized speical orientation
1°2°3°8°off C-axis 2inch dia 50.8mm size for epi-reday test
How About The Advantagement For Sapphire Common Lens Applications ?
- *Transmits Wavelengths Ranging From UV to Mid-Infrared
- *Features Extreme Surface Hardness and Chemical Resistance
- *Thinner and Stronger than Standard Glass Windows
What is Sapphire ?
Sapphire Windows are manufactured from Al2O3 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. , and is useful in
a transmission range from 0.2 - 5.5µm.
