Calcium Fluoride Crystal

Calcium fluoride (CaF₂) is a cubic crystal with an excellent transmission from 130 nm to 10 µm and has widespread applications as transparent windows in the ultraviolet and infrared spectra.

Calcium fluoride (CaF₂) is a very important optical functional crystal, which has good optical properties, mechanical properties and chemical stability. It can be used as optical crystal, laser crystal and inorganic scintillation crystal. It has a wide transmittance range (0.125-10 µm), and is widely used as optical medium from vacuum ultraviolet to mid infrared. CaF₂ crystal is an ideal optical material for achromatic lenses because of its special refractive index and relative dispersion. At present, deep UV excimer laser lithography is developing from 193 nm to 121 nm.

Advantages of CaF₂:

CaF₂ single crystal has the advantages of good ultraviolet transmittance, high laser damage resistance threshold, low stress birefringence and high refractive index, which makes it the best choice for the research of deep UV excimer laser lithography. In terms of laser applications, laser diode-pumped CaF₂ crystals activated by trivalent rare earth ions such as Er³⁺, Tm³⁺, and Yb³⁺ are obtained at room temperature.

NCE supplies high quality CaF₂ or Calcium Fluoride Crystal in mass production quantity. Material from NCE features with high transmittance in UV and IR wavelength ranges. NCE offer supplies [001] cut (i.e. the surface is perpendicular to the [001] axis) high quality CaF₂ windows for continuum generation. CaF₂ windows cut along a random orientation and polycrystalline CaF₂ windows are also available. In addition, we can also provide other types of window crystals like YAG crystals, BaF₂, MgF₂, LiF crystals, MgO, etc.
