Abstract

The 1959 cm-1 KBr impurity absorption in beamsplitters provides a convenient measurement of instability that may be used in conjunction with interferogram fluctuations to assess the total instrumental instability. Analysis of interferogram fluctuations led to environmental controls which reduced the KBr impurity band contribution in a ratioed spectrum to less than 0.9%, and facilitated measurement of sub-milliabsorbance infrared bands.
