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. It shares similar optical properties with Barium Fluoride although it has a transmission that is 2.5µm less into the infra-red. Calcium Fluoride is however cheaper than Barium Fluoride as the optical grade occurs naturally as opposed to BaF2 being man made.

Knight Optical supply a range of quality CaF₂ prisms either from stock or bespoke custom made to your specification for a range of applications. Every component is individually tested by our highly skilled technicians in our state of the art metrology lab to ensure all components meet our high quality standards. Stock windows are available in 45° right angled types and 60° equilateral types in 15mm to 30mm length.
