Infra-Red (IR) Grade
In the past CaF2 was mined and was inexpensive compared to other grades. But now regent grade CaF2 is used to save money.
Ultra-Violet (UV) Grade
Synthetically produced CaF2. Tranmission through Ultra Violet-Visible spectrum as well as the IR.
Vacuum Ultra-Violet (VUV)
The vacuum UV part of the spectrum extending to the theoretical limit for CaF2.
Eximer Grade
Eximer grade CaF2 is derived from pure crystal ingots of the highest purity to guarantee the best absorption of high-powered lasers.
Raman Grade
Only certain CaF2 ingots that meet the highest quality can be deemed Raman grade.

CaF2 for FTIR
Researchers use CaF2 for Fourier-transform infrared spectroscopy (FTIR). This method obtains the infrared spectrum of absorption or emission of a solid, liquid or gas. An FTIR spectrometer simultaneously collects high-spectral-resolution data over a wide spectral range.
