What is the usage of sapphire windows in optics?
Sapphire is frequently used in optical windows,optical spherical lenses, and other optical components. Additionally, sapphire is often used in high-powered lasers due to its ability and durability to withstand high temperatures. If you need an optical material that can stand up to the most demanding applications, Yutai Optics highly recommend optical grade sapphire for you.
Spectrum of sapphire glass windows
Sapphire has an extremely wide transmission spectrum (150 nm to 6.0 μm).Its high melting point（2045℃）, good thermal conductivity and low thermal expansion provide excellent performance in high temperature environments.
Sapphire crystal is the hardest oxide crystal, is the basic single crystal form of aluminum oxide (Al2O3).
