Advantagement On sapphire materials opical glass compare with other glass

1.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.
2.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 .
3.Excellent thermal shock stability
4.High transmission to 85%
5.Electric insulation ,it is 10000 times of usual glass
