Abstract
The UH Near Infrared Camera is equipped with a NICMOS-3 HgCdTe detector array sensitive from -1 to 2.5 microns and produced by the Rockwell International Science Center for the Near Infrared Camera and Multi Object Spectrometer Project (NICMOS). In our camera, the NICMOS-3 array operates with 53 electrons read-noise in double correlated sampling mode. A dark current below 1 electron per second at an operating temperature of 60 K has been achieved. The device works linearly within 1% up to 250000 electrons (2/3 full-well) at 1.0 V bias. Techniques for further reduction in read-noise and dark current are discussed. The only significant remaining problem is a residual excess dark current, remaining from previous exposure of the device.Keywords
