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.
