A standard Fused silica window has hydroxyl absorption (OH radical group) at wavelength 1.4μm, 2.2μm, 2.7μm. Anhydrous synthetic quartz is a special material that does not absorb water molecules in the molecular glass; therefore there is no hydroxyl absorption at the IR region.

◦The physical characteristics and optical properties of none hydroxyl absorption at IR region is the only difference from conventional synthetic quartz.
◦The material is physically robust and provide higher stability and is recommend for use in vacuum and high pressure environments.

▶We also offer AR coatings in accordance to your wavelength selection.
▶Product sizes and wedges which are not mentioned on our website or in this catalog are available, please ask our Sales Division.

Attention

▶Fluorescence illuminant may occur with strong UV light exposure. For high UV exposure applications we recommend CaF2 Windows (OPCF) and Excimer laser use Fused silica windows (OPSQK)
W3151, W3137.
▶Windows are offered standard with no AR coating and provide transmittance of 94% after loss of 3% for each surface.
▶Wavefront reflection and transmission is not guaranteed; for interferometer and high precision optical application, please contact our Sales Division with your custom requests.
