• Features Extreme Surface Hardness and Chemical Resistance
• Transmits Wavelengths Ranging From UV to Mid-Infrared
• Thinner and Stronger than Standard Glass Windows
TECHSPEC® Sapphire Windows are manufactured from single crystal sapphire, making them ideal 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. Sapphire is the second
hardest crystal next to diamond and, because of their structural strength, sapphire windows can be made
much thinner than other common windows with improved transmittance. Chemically, sapphire is single crystal
aluminum oxide (Al2O3) and is useful in a transmission range from 0,33 - 5,5 μm when uncoated. TECHSPEC®
Sapphire Windows are available with anti-reflection (AR) coatings to improve performance in the visible, NIR,
and IR spectra with coating options covering 400 - 5000 nm.
