The FDM ATR Dyes are a unique and practical solution to the problem of high refractive index values and correspondingly strong mid-IR absorbances, which can produce diamond or ZnSe (Zinc selenide) ATR spectra that appear distorted. The germanium spectra are generally free of this problem.  Having both diamond and germanium ATR/FTIR spectra gives users the ability to work with both types of ATR crystal and a better understanding of complex spectra.
