Calcium Fluoride(CaF2)1 has widespread IR application as spectroscopic windows, prisms and lenses. High purity grades of CaF2 find useful application in the UV and as UV Excimer laser windows. CaF2 is available doped with Europium as a gamma-ray scintillator.

Magnesium Fluoride(MgF2) transmits well into the VUV region to the hydrogen Lyman-alpha line (121nm) and beyond. MgF2 is used mostly for UV optics and is excellent for Excimer laser applications.

Barium Fluoride(BaF2) is used in spectroscopic components. BaF2 is often suitable for applications in the passive IR band (8 to 14um) and is often used as a viewport window for thermography. For an equivalent thickness the transmission extends approximately 1 micron further into the IR than Calcium Fluoride. Windows intended primarily for IR use and noted as having IR polish may have restricted transmission in the VUV being made from lower purity BaF2 crystal. The highest quality BaF2 also has application as the fastest known scintillator material and is used in High Energy Physics Experiments.

  1. Vacuum-Grade Calcium Fluoride; Broadband AR Coating upon request; Focal Lengths from -5 to -1,000mm; high transmission from 180 – 8,000nm; commonly used for applications requiring high transmission in the infrared and ultraviolet spectral ranges. The material exhibits a low refractive index, varying from 1.35 to 1.51 within its usage range of 180 nm to 8,000nm. Calcium fluoride is also fairly chemically inert and offers superior hardness compared to its barium fluoride, magnesium fluoride, and lithium fluoride cousins. ↩︎
