Paper Abstract

The evolution of Santa Barbara Research Center (SBRC) InSb focal plane arrays (FPA) for astronomy has been significant since the introduction of the SBRC 58 X 62 array in the mid 1980's. A 256 X 256 array, whose performance is evaluated herein, is currently available from SBRC, and a 1024 X 1024 InSb FPA is under development by the U.S. Naval Observatory (USNO). National Optical Astronomy Observations (NOAO), and SBRC. This represents an increase by a factor of approximately 300 in the number of pixels in less than 10 years, with attendant increase in performance as well. The availability of high performance infrared arrays has opened up the field of infrared astronomy. As this paper shows, the 256 X 256 InSb FPA is a great improvement over its predecessor in all areas of performance. Its most striking improvement is the complete absence of a latent or residual image after exposure to very high fluxes. Because of its low node capacitance, which results in very low read noise, the full well capacity is somewhat compromised.
