UIST

UIST, the UKIRT Imaging SpecTrometer, is a near infrared imaging-spectrometer for astronomy, developed and built at the UK ATC and installed on the UK Infrared Telescope (UKIRT). It is designed to have high angular resolution capabilities for both imaging and spectroscopy. In addition, it includes a cryogenic Integral Field Unit, giving 3-D spectroscopic capabilities.
