Abstract

Standard, off-the-shelf, large infrared detector arrays are now available that meet the demanding requirements of the astronomy and civil space communities. This paper describes arrays with more than one million detector elements (1024 × 1024 and 2048 × 2048 formats) developed by Raytheon Vision Systems for these low-background applications. Arrays of this size have been demonstrated with a variety of detector materials: Si PIN, HgCdTe, InSb, and Si:As IBC. All of these detector materials have demonstrated low noise and dark current, high quantum efficiency, and excellent uniformity over wavelengths ranging from visible (optical) to 28 μm. Features of the readout integrated circuits that mate to these detector arrays are also discussed. Summary performance data of each of these materials on arrays with more than one million detector elements are presented. Companion papers in these SPIE proceedings that discuss several of these arrays in more detail are: • "2K × 2K HgCdTe Detector Arrays for VISTA and Other Applications," P. J. Love, A. W. Hoffman, K.

Ritchie, R. S. Holcombe. • "2K × 2K InSb for Astronomy," A. W. Hoffman, E. Corrales, P. J. Love, J. P. Rosbeck, A. M. Fowler, M. Merrill. • "Mosaic Packaging for Large Format Infrared Devices," R. S.
