Why Choose sapphire crystal?
1. Thinner and Stronger than Standard Glass Windows
2. Transmits Wavelengths Ranging From UV to Mid-Infrared
3. Features Extreme Surface Hardness and Chemical Resistance
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 diamonds and, because of their structural strength, sapphire windows can be made much thinner than other common dielectric windows with improved transmittance. Chemically, sapphire is single crystal aluminum oxide (Al2O3), and is useful in a transmission range from 0.2 - 5.5µm.
Optical crystals are used as view ports to protect other components within an optical assembly, instrument, or laser. In certain applications, optical crystals are required to withstand harsh environmental conditions and provide high levels of performance and reliability. Sapphire crystal has several unique properties that make it the ideal material for these applications.
