Abstract

The 10⁵ resolution spectrograph 'CRIRES' for the 1-5 micrometers wavelength range is under construction for ESO's Very Large Telescope. The Nasmyth-mounted instrument sues an adaptive optics front-end for light concentration and 0.2 arcsec spatial resolution in the main long-slit spectroscopy mode. Three detector arrays will be used for large single- order wavelength coverage. Many components for this large cryogenic spectrograph are based on developments for earlier ESO IR instruments.
