NICMOS uses three 256 x 256 HgCdTe Rockwell arrays, one in each camera. We report on their measured detector quantum efficiency (DQE), read-noise, and dark current which have been determined at the unit test level prior to the 1996 thermal vacuum characterization. Other aspects of their expected performance are discussed here, including shading, linearity and saturation, cosmic ray susceptibility and flat fielding.
