The TIRVIM Fourier Spectrometer for Studying the Martian Atmosphere

The design and performance features of an IR Fourier-transform spectrometer for studying the Martial atmosphere in the spectrum range of 600–5500 cm–1 during the ExoMars-2016 mission are described. The obtained spectral resolution is in agreement with the theoretical value (0.2 cm–1); the threshold of the instrument sensitivity is approximately 0.1 mW/(m2 sr cm–1).
