Calcium Fluoride (CaF2) Components

  • useful transmission over the spectral range from 0.2 to 8.0 microns
  • low soluble

Low solubility and wide transmission range makes it useful for many applications, including:

  • mirror substrate for UV laser systems;
  • substrate for manufacturing windows, lenses for UV, IR applications.

Two grades of material are available:

  • for UV
  • for IR applications.

Due to its composition CaF2 (Calcium Fluoride) has much longer useful life than most materials when used in a fluorine environment.


Calcium Fluoride (CaF2) lenses, windows, mirrors, prisms, beamsplitters and beamselectors are available upon request.
