The CRIRES instrument

The CRIRES Instrument, located on the Nasmyth-platform of VLT Unit Telescope 1, Antu. CRIRES is the cryogenic high-resolution infrared echelle spectrograph, which provides a resolving power of up to 100 000 in the spectral range from 1 to 5 microns. CRIRES can boost all scientific applications aiming at fainter objects, higher spatial (extended sources), spectral and temporal resolution. CRIRES also allows astronomers to make use of the innovative 'spectral imaging' method.
