Optical glass flat  Windows(BK7, Fused silica,CaF2)  

 BK7 is a high quality optical glass that is used whenever the additional benefits of fused silica are not required. Since BK7 performs well in all chemical tests, and no additional or special handling is required, costs of manufacturing are reduced.



Calcium Fluoride Optical Windows


  • 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.
