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 lenses 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 lenses are available in a range of commonly requested sizes between 12.7mm diameter to 38.1mm diameter and up to 500mm focal length. Stock lenses can be edged down in house to meet individual customer's requirements.
