Paper Abstract

The cryogenic infrared camera, IRCAM, has been operating routinely on the 3.8m UK Infrared Telescope on Mauna Kea, Hawaii for over two years. The camera, which uses a 62 x 58 element Indium Antimonide array from Santa Barbara Research Center, was designed and built at the Royal Observatory, Edinburgh which operates UKIRT on behalf of the UK Science and Engineering Research Council. The system is capable of read noises of about 450 electrons rms and dark currents of about 100 electrons per second. IRCAM achieves background-limited performance throughout the 1 - 5 micron region for all broad-band imaging applications and even for narrow passbands (1% of the wavelength) for wavelengths longer than 2 microns. Performance characteristics including linearity and spatially non-uniform response are discussed. Over the past two years at least 60% of the available time on UKIRT has been allocated for IRCAM observations. Examples are given of recent results which illustrate the power of IR imaging in astrophysics.
