Advantagement for Sapphire physical property
1 -Thinner and Stronger than Standard Glass Windows
2 -Transmits Wavelengths Ranging From UV to Mid-Infrared
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.
