New 8–13 µm Si:Ga/DRO Hybrid Arrays for Very Large Telescopes

Since 1984, the CEA-LETI-LIR (Infrared Laboratory) has been involved in development of Si:Ga/DRO hybrid detector arrays dedicated to imaging of astronomical sources in the 8–13 μm range. Successively, 32×32 element arrays were successfully manufactured for the ISOCAM camera and 64×64 arrays were fabricated for ground-based imaging. The latter detectors have been integrated in 3 cameras (C10μ, CAMIRAS and TIMMI for ESO) and have led to excellent astrophysical results since 1990.
