What is 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. Chemically, sapphire is single crystal
aluminum oxide (Al2O3), and is useful in a transmission range from
0.2 - 5.5µm.
Rod Lens is designed for use in a variety of laser and imaging
applications. The addition of this product line is part of a continued effort to
support current trends toward miniaturization.
