Product Description

 

Infrared Detector CaF2 widnows

Calcium Fluoride (CaF₂) is commonly used for optics looking at the IR and UV spectrums and has a very low change in refractive index with wavelength.

 

Our CaF2 window is selected by many flame detector manufacturers, and we keep long-term cooperation. According to the design requirements of each customer, we continuously supply windows of different specifications.
