Synthetic sapphire—sometimes referred to as sapphire glass—is commonly used as a window material, because it is both highly transparent to wavelengths of light between 150 nm (UV) and 5500 nm (IR) (the visible spectrum extends about 380 nm to 750 nm, and extraordinarily scratch-resistant.

The key benefits of sapphire windows are:

Very wide optical transmission band from UV to near-infrared, (0.15–5.5 µm)
Significantly stronger than other optical materials or standard glass windows
Highly resistant to scratching and abrasion
Extremely high melting temperature (2030 °C)


We can supply professional customized service in time and provide cooperation and support of new product development and technology appliance.

Some other materials semi substrates also can be provided as like sic, GaN,LaAlO3,LiTaO3 etc.
