Scientific paper

Two IR detectors have been selected as prime and spare flight parts for the IR channel of the Wide Field Camera 3 (WFC3). WFC3 is the panchromatic camera to be installed on the Hubble Space Telescope in Servicing Mission 4. The two devices, produced by Rockwell Scientific, are based on HgCdTe photoactive material MBE grown on ZnCdTE substrate with cutoff at 1.7μ m, and are hybridized on a 1Kx1K Hawaii-1R multiplexer. We present the detector performances, as result from the tests performed at the Detector Characterization Laboratory at the NASA-Goddard Space Flight Center. On the basis of the observed parameters, we estimate the sensitivity of the instrument in a number of representative filters and observing modes.
