Abstract
Rockwell Science Center and the University of Hawaii have developed a short wavelength infrared (SWIR) 1024 X 1024 focal plane array (FPA). The continuing project is funded by the U.S. Air Force Phillips Laboratory in connection with their Advanced Electro Optical System (AEOS) 3.67 m telescope project on Haleakala, Maui. We have achieved our objective of developing a 1024 X 1024 FPA with a cut-off wavelength of 2.5 micrometers . The device is named the HgCdTe Astronomical Wide Area Infrared Imager (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 of prior astronomical 256 X 256 FPAs), total FPA dark current < 0.1 e-/sec at 77 K, pixel yield > 99%, quantum efficiency > 50%, BLIP-limited sensitivity at low-109 photons/cm2-sec background and operating temperatures to 120 K, and read noise < 10 e-.
