Sapphire (Al2O3) is an excellent infrared optical window / substrate material with a transmission range of 0.2-5.5um, high temperature resistance and high hardness, second only to diamond, and resistant to acid and alkali corrosion. Sapphire substrates can also be used for epitaxial wafers in the semiconductor industry, for making LEDs, etc.
We provide sapphire substrate and window materials with excellent performance, and can process different sizes and shapes according to your requirements to ensure excellent optical performance.

Double-sided polishing, crystallization direction: C-axis, spot.
Other crystal planes such as A and R planes can be customized.
