ICC Optical Glass Window Sapphire Al2O3 Crystal Protect Windows
Sapphire (Al2O3) Windows
Sapphire is used for its extreme toughness and strength. Sapphire is a very useful optical window material for use in the UV,visible, and near infra-red.
Features
* Ø1/2" and Ø1" Versions Offered
* Uncoated Wavelength Range: 150 nm - 4.5 µm
* Available with AR Coating for 1.65 µm - 3.0 µm or 2.0 µm - 5.0 µm on Both Sides
* Stable Performance over a Wide Temperature Range
Our Sapphire Precision Windows are available in 1/2" and 1" diameters. The uncoated versions are designed for applications in the 150 nm - 4.5 μm range. AR-coated windows feature anti-reflective coatings designed for 1.65 µm - 3.0 µm (-D) or 2.0 µm - 5.0 µm (-E1) on both sides.
