Why choose the sapphire?
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 rods 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.
