Uncoated Optical Sapphire windows

Sapphire Windows are manufactured from single crystal sapphire AI2O3, its advantage is extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. Specifications: Material : Sapphire AI2O3 Diameter : 1mm ~ 300mm Diameter Tolerance :+0.0/-0.1mm Thickness Tolerance :+/-0.1mm Surface Quality :40/20， 60/40 Clear Aperture :>90% Bevel : Protective bevel as needed Coating :Upon your request Sapphire (molecular formula Al2O3) single crystal is an excellent multifunctional material. It has high temperature resistance, good thermal conductivity, high hardness, infrared transmission and good chemical stability. Widely used in many fields of industry, national defense and scientific research (such as high-temperature infrared windows, etc.). At the same time, it is also a widely-used single crystal substrate material. It is the preferred substrate for the current blue, violet, and…
