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.
