1 -Thinner and Stronger than Standard Glass Windows
2 -Transmits Wavelengths Ranging From UV to Mid-InfraredC - Axis Sapphire Wafer Single Side Polished 3 Inch Al2O3 Crystal Optical Lens 1
3 -Features Extreme Surface Hardness and Chemical Resistance

4. -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.
5. -Corrosion resistant, Except hydrofluoric acid, Quartz Plate Of  

     Optical Grade do not react with any acid and base except hydrofluoric acid.the stability is 30 tims of the ceramic,and 150 times of stainless steel .
6. -Excellent thermal shock stability
7. -Electric insulation ,it is 10000 times of usual glass


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.
we can supply professional customized service in time and provide cooperation and support of new product development and technology appliance. and other materials semi wafers also be provided.
