Sapphire Optical Windows Customizable 99.99% Al₂O₃ High Transparency for Laser Windows
Sapphire windows are made from single-crystal aluminum oxide (Al₂O₃), characterized by high hardness, excellent transparency, high-temperature resistance, and corrosion resistance. They are widely used in optical systems and harsh environments. Naturally occurring as corundum, this material can be finely processed to produce high-quality optical windows.
