NICMOS - A 2ND GENERATION INFRARED INSTRUMENT FOR THE HUBBLE-SPACE-TELESCOPE

NICMOS (the Near Infrared Camera and Multi-Object Spectrometer) is a second generation scientific instrument for the Hubble Space Telescope (HST). Three cryogenic cameras with 256x256 HgCdTe arrays provide diffraction limited imaging throughout the 0.8 - 2.5 mu m spectral region. Grisms in one of the cameras produces multi-object spectroscopy for all objects in the field. Coronagraphic and polarization capabilities round out the NICMOS modes of operation. Scheduled for launch on the second HST maintenance mission in 1997, NICMOS has a five year on-orbit cryogenic lifetime.
