CaF2 Window

Calcium fluoride is often used in spectroscopic windows and lenses due to its high transmission from 250nm to 7μm.

Calcium Fluoride (CaF2) Windows commonly used in cryogenically cooled thermal imaging systems.Calcium Fluoride (CaF2) windows for IR and UV applications. Other calcium fluoride (CaF2) components include CaF2 lenses, mirrors, prisms are available

Calcium Fluoride Optical Window

  • High average transmittance
  • Low chormatic aberrations
  • Ideal for UV to NIR applications (180 nm to 8 µm)
  • Availabe in 9 sizes from 5.0 mm to 50.0 mm diameter

It is a relatively hard material with extremely low bubble and inclusion content, while providing excellent transmittance through-out the visible and near infrared spectra and down to 350 nm in the ultraviolet.

The material can be Schott, or CDGM optical glass serious. They are low distortion, low scatter, and could be for laser and non-laser applications.
