The important optical property of sapphire optics is the high optical transmission inside broad spectral range from VUV to IR. Sapphire Al2O3 optics is transparent in wide spectral range from 0.17 to 5.5 microns. Besides, high optical transmission of sapphire combines with the excellent mechanical strength properties (both at low and at high temperatures), high abrasion resistance and chemical stability. So sapphire windows and sapphire plates have wide application in the industry and instrument engineering, including as excellent sapphire laser windows. Sapphire plane parallel windows are used as transfer optics, including protective windows. Crystaltechno Ltd. manufactures sapphire windows from sapphire monocrystalline material. Moreover we make plane parallel windows and plates from another optical crystals, glass and fused silica.
