Abstract

A cryogenic echelle spectrometer is planned for the ESO Very Large Telescope to perform high-resolution (R >= 100,000) observations in the 1 - 5 micrometers range. Primary design goals are optical quality to exploit the 8 m telescope advantage and large spectral field to exploit the sensitivity advantage of a dispersive instrument with a large detector array. The basic instrument uses established technology; some components potentially leading to enhanced performance or additional capabilities are under development.
