Abstract

An optical or Fourier infrared Fourier spectrometer with a two-beam interferometer with which the mirror drive is effected via two retroreflectors which are located on two 180.degree. displaced arms of a double pendulum. Deflecting mirrors are arranged between the beam splitter and the retroreflectors. The otherwise usual retroreflecting mirrors are not present. The beam splitter is displaced with respect to the plane of the pendulum. Thereby, a stable, easily aligned, and compact configuration is effected.
