Paper Abstract

The optical configurations adapted for the IR Imaging Spectrometer (IRIS) designed for AAT are described together with the mechanical design of the spectrometer. The direct imaging of IRIS will provide a number of different angular scales and corresponding fields, with remotely controlled field selection amongst a subset of these. With the widest field, each 0.06-mm pixel will be 2 arcsec; with the narrowest field, it will be about 0.1 arcsec square. The IRIS will be used at both the f/15 and f/36 Cassegrain foci, for the wide-field imaging and the spectroscopy, respectively. Diagrams of optical configurations and the mechanical assembly of IRIS are presented.
