Abstract

Two DRS Technologies (formerly Boeing Sensors and Electronic Systems) 256 x 256 Si:As Blocked Impurity Band (BIB) focal plane arrays have been rigorously tested in 2001 and 2002 in the IR laboratory of CEA/Saclay/Service d'Astrophysique. These mid-IR arrays equip VISIR, the mid-infrared imager and spectrometer made under contract by CEA (France) and ASTRON (Netherlands) for the ESO Very Large Telescope. Measurement results crucial to the project appliction are presented. These include array dark current versus temperature and the Background Limited noise Performance (BLIP) capability. Operational optimization for astronomical use is also discussed in this paper.
