Sapphire Glass
Sapphire Glass is widly used in many optical filed, it can resist scratches, Acid and Alkali attack, Shocks, beacause it's good machinical properties. While sapphire Glass have good machinical Properties, they also have a superior optical index.
Typically, it can transmitt the light from 190nm~2100nm. from DUV~IR.
Size we can offer: From φ2mm~φ200mm Thickness：From 0.5mm~50mm
Surface Quality : Up to 10/5 S/D Surface Flatness: Up to λ/10 @633nm
