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 custom requirement. We are also able to provide coated products with AR coating through 1.65µm or 2-5µm.
CaF2 has high caf2 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 imaging performance compared to regular optical glasses.
