Paper Abstract

The design of a multimode IR spectrometer/imager for the ESO VLT is discussed. The system has two cameras optimized separately for the 1-2.5-micron and 2.5-5.0-micron spectral regions, used to either view the on-axis focal plane for direct imaging or to reimage the intermediate spectrum formed by a grating spectrometer whose input slit is located a few arcmin off axis. The characteristics of the imaging and the spectrometry are described, and a diagram of the opticaL layout of the system is presented together with the spot diagrams for the camera objectives and for the combined spectrometer/camera.
