CRIRES - CRyogenic high-resolution InfraRed Echelle Spectrograph
Note that CRIRES will be removed from UT1 in July 2014 for an upgrade. The instrument will not be offered from P94 onwards. CRIRES plus is expected to return to Paranal sometime during 2017.
CRIRES plus is described on the following webpage
The VLT cryogenic high-resolution infrared echelle spectrograph CRIRES is located at the Nasmyth focus A of UT1 (Antu). It provides are solving power of up to 105 in the spectral range from 1 to 5.3μm when used with a 0."2 arcsec slit. CRIRES can boost all scientific applications aiming at fainter objects, higher spatial(extended sources), spectral and temporal resolution. Simultaneous spectral coverage is maximized through a mosaic of four Aladdin IIIInSb arrays providing an effective 4096 x 512 focal plane detector array in the focal plane. Adaptive Optics (MACAO - Multi-Applications Curvature Adaptive optics) is used to optimize the signal-to-noise ratio and the spatial resolution.
Publications based on data obtained with the CRIRES instrument should quote the following reference paper: Käufl, H.U. et al. 2004, SPIE, 5492, 1218 .
