Abstract

We have carried out a conceptual design study for a near-infrared (NIR) wide-field camera and a mid-infrared (MIR) camera-spectrograph for a 2.5 m telescope at Dome C. The main scientific drivers are the characterisation of young embedded objects, the evolution of crystalline silicates in circumstellar disks and the observation of exoplanet secondary transits. Both instrument exploit the unique features of Dome C: improved infrared transmission, reduced sky background, superb seeing, low temperature, and increased atmospheric stability. The NIR camera covers the wavelength range 0.8–5.5 μm and is optimized for the Kdark and L bands. The MIR instrument is sensitive in the range 7–40 μm with a possible extension to the sub-mm. It is optimized for the Q window, including the Q+ extended portion (25–40 μm) only observable from the Antarctic Plateau.
