Uncoated 180 Nm Optical Glass Windows CaF2 Calcium Fluoride Windows
Uncoated Windows for 180 nm to 8 µm Calcium Fluoride (CaF2) Ultraviolet and Infrared Windows φ5-100mm
Offers calcium fluoride (CaF2) High-Precision Windows either uncoated or with a broadband anti-reflective coating. 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. Given its low absorption coefficient and high damage threshold, uncoated calcium fluoride crystal is a popular choice for use with excimer lasers. CaF2 windows are also commonly used in cryogenically cooled thermal imaging systems.
Calcium fluoride has a low absorption coefficient and high damage threshold, making these windows a good choice for use with free-space lasers. Optical calcium fluoride offers low dispersion (with an Abbe Number of 95) and low fluorescence, as well as excellent water, chemical, and heat resistance. In dry environments, 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.
offers flat windows fabricated from N-BK7, UV Fused Silica, Sapphire, Calcium Fluoride, Magnesium Fluoride, Potassium Bromide, Infrasil, Zinc Selenide, Silicon, Germanium, or Barium Fluoride. Our laser windows have a wavelength-specific AR coating centered around commonly used laser wavelengths and an optional wedge, while our precision windows are offered with or without a broadband AR coating.
