Sapphire windows
Sapphire has good light transmission in the 0.20~5.50μm band, and is an ideal laser and infrared optical material. It is widely used in endoscopes, surface mirrors, optical lenses, surface acoustic wave devices, infrared windows, filters, High and low temperature observation window, photon beauty instrument window, etc.
Sapphire is also an ideal material for GaN, GaAs and other integrated circuit substrates and epitaxial substrates.
There are mainly circular slices, elliptical slices, oblique circular slices, stepped window slices, etc.
