Detailed Description
sapphire led substrates,z sapphire wafers ,sapphie optical wafers semiconductor substrates ,sapphire optical windows,Al2O3 crystal wafer for led,
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 1200C continuously,and in short time can even work under 1450C,
its softening temperature is 1650C,and the melting temperature is 1750-1800C.
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
The process of our sapphire wafer lens
