Design and performance of a high-resolution Fourier transform spectrometer for laboratory molecular spectroscopy in the 8-200-cm-1 region are discussed. A folding of the beam path is used to obtain the maximum path difference of 4 m with a mirror stroke of 1 m. The measured linewidth of 0.0019 cm-1 is in agreement with the expected theoretical resolution.
