The air slits applied to MMS. a) The illustration of the slits for the V-NIR and N-MIR channels. Lengths of the nadir area, block area and calibration area are 12.8 mm, 1.9 mm and 1.3 mm respectively. The block areas are used for the dark current reference acquired. b) The micro-optical parts assembled on the side of the V-NIR slit for coupling fiber-optic signals. The micro-optical part of the N-MIR channel has the same structure as the one of the V-NIR channel
