Abstract

The optical and the cryogenic designs for IR imagers and spectrographs of the 8-m UK Large Telescope (UKLT) are described. Performance figures for astronomical observations are presented showing that the basic designs can be matched to the range of optical configurations of 3.5 to 10 m telescopes. A diagram of the cryogenic spectrometer for the UKLT showing the layout of optical elements is presented together with schematics of the f/7 imager.
