The SPICAM instrument has two channels, one in the ultraviolet wavelength range - 118-320 nm (named SUV), and another (named SIR) in the near infrared wavelength range - 1.1-1.7 micrometers. The UV channel is a spectrometer with an optical baffle, an off axis parabolic mirror, a slit with two positions, a grating and a detector with an intensified CCD. The IR channel is made of an entrance lens, an AOTF and two single pixel detectors (for each polarization). As the AOTF acts as a filter, the IR spectrum is obtained by electrically scanning the AOTF frequency.
