Thermal Infrared Imaging Spectrometer (TIS) on-board Mars Orbiter Mission (MOM) is a grating based spectrometer whichmeasures thermal infrared radiation emitted from Mars environment in 7-13 µm spectral range. Observations from TIS help in estimating brightness temperature of Mars surface and in knowing the composition of the surface. TIS is made up of light weight miniaturized components (total weight 3.2 kg) and has power requirement of 6W and uses un-cooled micro-bolometer array for detection.
