CRIRES+: Exploring the Cold Universe at High Spectral Resolution
Abstract
The CRIRES upgrade project, CRIRES+, transforms this VLT instrument into a cross-dispersed spectrograph to increase the wavelength range that is covered simultaneously by a factor of ten. In addition, a new detector focal plane array of three Hawaii 2RG detectors with a 5.3 μm cut-off wavelength will replace the existing detectors. For advanced wavelength calibration, custom-made absorption gas cells will be added. A spectropolarimetric unit will allow circularly polarised spectra to be recorded. These upgraded capabilities will be all supported by dedicated data reduction software which will allow the community to take full advantage of the new capabilities offered by CRIRES+.
