Sapphire Plane Parallel Windows - Sapphire Al2O3 Optical Windows

MATERIAL - Sapphire Al2O3 Single Crystal



The important advantage of sapphire optics is the high optical transmission in 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.

We manufacture the large-sized sapphire windows-plates with composite geometrical shape profile. Sapphire windows sizes - 350 x 350 x 30 mm. Maximum available sapphire plates sizes are 350x500x30 mm.
The broadband antireflection AR coating technology of the big sapphire windows is debugged.

Our optical products have aroused customers interest, especially a large-sized sapphire optics with antireflection coating: AR broadband coated sapphire protective windows.

Perhaps you will find required sapphire windows or other sapphire optics at our stock, please see item Optical Crystals.
