special shape sapphire optical lens with hole , Al2O3 single crystal glass, optical glass sapphire wafer,sapphire glass plate
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.
Merit from Comparison with other material optical lens
1-Thinner and Stronger than Standard Glass Windows Because Hradeness9.0
2- can use in Close to 2000° temperature environment
3-Transmits Wavelengths Ranging From UV to Mid-Infrared
4-Features Extreme Surface Hardness and Chemical Resistance
