Rockwell Science Center and the University of Hawaii have developed a short wavelength infrared (SWIR) 1024 x 1024 focalplane array (EPA). The continuing project is funded by the U.S. Air Force Phillips Laboratory in connection with their AdvancedElectro Optical System (AEOS) 3.67 m telescope project on Haleakala, Maui. We have achieved our objective of developing a 1024 x 1024 EPA with a cut-off wavelength of 2.5 im. The device is named the HgCdTe Astronomical Wide Area InfraredImager (HAWAII). The first hybrids have been characterized, delivered and first light achieved two days ahead of schedule; performance highlights include successful elimination of the reset anomaly (whose presence limited the noise performance ofprior astronomical 256 x 256 FPAs), total FPA dark current 99%,quantum efficiency > 50%, BLIP-limited sensitivity at Iow-109 photons/cm2-sec background and operating temperatures to 120K, and read noise < 10 e-.
