Company Profile

12" Sapphire Glass Wafer

ultrathin sapphire glass wafer ,4inch 0.5mm C-axis sapphire wafer for epi-ready,sapphire thick glass lens for covering,sapphire optical windows,4inch 0.3mm thickness sapphire wafer,

diameter300mm 12inch double side polished sapphire glass wafers window with notch for semiconductor carrier wafer

Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.Sapphire , so making them ideal materials for demanding applications (such as laser systems) because of their extreme surface hardness, high thermal conductivity, high dielectric constant and resistance to common chemical acids and alkalis. And sapphire also is the second hardest crystal next to diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance.
