Product Description
8 Inch Dia 200mm Sapphire Wafer By 1.0mm Thickness 1sp For Epi - Ready Carrier
Single crystal sapphire Al2O3 possesses a unique combination of excellent optical, physical and chemical properties. The hardest of the oxide crystals, sapphire Al2O3 retains its high strength at high temperatures, has good thermal properties and excellent transparency.
The main application of optical sapphire is large aperture windows, viewports, illuminators for common-aperture optical systems (visible+IR) what make sapphire the top actual material due to its optical and mechanical properties.
Sapphire products are used in many fields as optical details (windows, plates, light guides and lenses, especially sapphire plane-parallel plates - windows, optical high-temperature substrates, exact mechanics details, bulbs of high pressure lamps and so on.
