Researchers tested 58 x 62 low-doped InSb diode arrays bonded to MOSFET readouts for their performance potential in a low background space environment. Of primary concern were the quantum efficiency, dark current and read noise. The quantum efficiency (45 percent at 3.3 microns) and dark current (less than 2.4e(-)/s) were found to be adequate for the Space Infrared Telescope Facility (SIRTF) experiments, while the read noise (200 e(-) RMS) was found to be wanting. More subtle concerns, such as image quality, linearity/calibratibility and flat fielding were also investigated. In these respects the arrays appear to be well suited for the high sensitivity, photometric accuracy, and image clarity demanded by the SIRTF experiments.
