Calcium Fluoride Lenses

Hyperion Optics supplies uncoated 1/2 inch and 1 inch in diameter Calcium Fluoride (CaF2) lenses. Please talk to our technicians for your customrequirement. We are also able to provide coated products with AR coating through 1.65µm or 2-5µm.

CaF2 has high transmission rate through 0.18-8.0 microns, used for UV and IR spectral high transmission applications. With its outstanding laser power damage threshold CaF2 lenses also are widely used under excimer laser environment. Its refractive index is comparatively low from 180nm up to 8.0 microns, ranges from 1.35 to 1.51. CaF2 has low dispersion, in visible wavelength applications, it shows superior vivid and exquisite imagingperformancecompared to regularoptical glasses.

Calcium Fluoride (CaF2) lenses transmission

However, Calcium Fluoride components are difficult to manufacture in actual production. The material itself is soft and easy to leave fabrication marks and scratcheson the polished surfaces. At Hyperion Optics, with our decade experience of CaF2 production, we have outstanding surface accuracy and cosmetic control method, our typical surface quality grade is 40-20 according to MIL-C-13830A.
