Calcium Fluoride Optics

Calcium Fluoride (CaF2) Optical Components are used as spectroscopic windows or lenses, or in cryogenically cooled thermal imaging systems. Calcium Fluoride (CaF2) Optics are ideal for a broad range of Ultraviolet (UV), Visible, or Infrared (IR) applications. Calcium Fluoride’s combination of low absorption with a high damage threshold makes it an excellent material for use with Excimer lasers. Calcium Fluoride (CaF2) features a low refractive index, removing the need for an anti-reflection coating.

Edmund Optics offers a wide selection of Calcium Fluoride (CaF2) Optical Components, such as Optical Windows, Optical Lenses, Prisms, or Beamsplitters. Calcium Fluoride (CaF2) Optical Windows are ideal for use as spectroscopic windows. Calcium Fluoride (CaF2) Optical Lenses are used in many spectroscopy applications. Calcium Fluoride (CaF2) Prisms are used for many broadband applications from the Ultraviolet (UV) to the Infrared (IR). Calcium Fluoride (CaF2) Beamsplitters are designed to be used at a 45° angle of incidence for broadband Infrared (IR) applications.
