CaF2 or Calcium Fluoride 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. Descriptions: CaF2 or Calcium Fluoride 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. 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 Er3+, Tm3+, Yb3+ and other 3-valent rare earth ions were obtained at room temperature. Main application: 1) VUV , UV ,IR optical systems 2) CaF2 crystals used for stable femtosecond white light generation from UV to IR. Why Choose HGO ? HG OPTRONICS.,INC. has the ability to supply high quality CaF2 or Calcium Fluoride Crystal in mass production quantity. Material from HGO features with high transmittance in UV and IR wavelength ranges. HGO 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 produce other types of window crystals like YAG crystals, BaF2, MgF2,LiF Crystals, etc. HGO has a mass-production line for CaF2 crystals and have wide experiences and strong ability to supply such crystals with large quantity and in very short delivery time.
