Abstract

The development and evaluation of an integrated array of antimony-doped silicon detectors is described. The spectral range of extrinsic silicon integrated arrays useful for low-background infrared astronomical applications is extended to about 31 pm with this development. The 58 x 62-element array is accessed by a direct readout (DRO) multilplexer. The device is evaluated with a flexible microcomputer-based drive and readout electronics system in a low-background test dewar. Acceptance testing indicates single-pixel NEPs in -18 the mid-10 W/?Hz range, and good global uniformity statistics.
