It provides diffraction-limited imaging at high sensitivity in three mid-infrared (MIR) atmospheric windows: the M-band at 5µm, the N-band between 8 to 13μm and the Q band between 17 and 20μm, respectively. In addition, it features a long-slitspectrometer with a range of spectral resolutions between 150 and 30000.
