Product Description

CaF2 Windows, Excimer Laser Windows, 180nm-8µM

Overview:

Calcium Fluoride (CaF2) Window is a popular choice for use with excimer lasers with the feature of its low absorption coefficient and high damage threshold.

 

Star Optic offers either uncoated or with a broadband anti-reflective coating for our Calcium fluoride (CaF2) windows. The uncoated windows provide high transmission from the ultraviolet (180 nm) to the infrared (8 μm). The AR-coated windows feature an antireflection coating on both sides that provides increased transmission within the 1.65 - 3.0 µm specified wavelength range.

 

In dry environments, Calcium fluoride (CaF2) can be used up to 1000 °C, but in the presence of moisture, degradation will occur for temperatures exceeding 600 °C. Each window has a randomly oriented crystal axis.

 

Calcium fluoride (CaF2) windows are also commonly used in cryogenically cooled thermal imaging systems.
