Compared with glass windows, sapphire optical windows have superior abrasion resistance, toughness, and fracture resistance.
The sapphire windows we produce are from sapphire crystal grown by the Kyropoulos method. We can provide processing services as well, for example: according to customer requirements to surface finish polishing, edge chamfer, laser cutting, coatings-addition, subtraction or customization.
