Abstract
The construction of a high resolution (0.005-cm−1) Michelson interferometer with cat's eye retroreflectors is described in some detail. The instrument line shape function of the Fourier spectrometer at 0.63 μm agrees with theory at 0.02-cm−1 resolution. Absorption spectra of gases have been measured using a 40-m White cell. Infrared luminescence spectra have also been measured using a calcium fluoride crystal doped with divalent dysprosium, cooled to 4.2 K, and excited with radiation from a quartz halogen lamp.
