Sapphire polished windows are extremely hard and scratch resistant useful for the visible and ir spectrum. Optical sapphire is made to a random orientation or cut to a specified orientation. It has excellent thermal conductivity at low temperatures allowing single crystal sapphire to be used in many diverse fields requiring thermal conduction and heat radiation. Sapphire has high dielectric constant and is resistant to common chemical acids and alkaline. Optical sapphire has no colouration and with a selection of grades of sapphire transmission ranging from 170nm to 6 microns see materials data sheet for more information
Sapphire windows can be made in various shapes, sizes and forms ie squares, plates, rectangles and discs, with various processing to the faces and edges. These come in a wide range of sizes see custom processing for details or select from a standard stock range.
Examples of typical applications and products for sapphire windows include: substrates, optical flats, pressure windows, viewing windows, cover plates, discs, coin sensors, thermocouple protection tubes, infrared measuring devices, laser windows, scanner windows, reaction furnaces, coating substrates, vacuum equipment, cryogenic systems and blue LED’s.
