CRIRES
(Cryogenic Infrared Echelle Spectrometer)
(high resolution IR echelle spectrometer)
CRIRES (Cryogenic Infrared Echelle Spectrometer)
is a high spectral-resolution infrared spectrograph
on European Southern Observatory Very Large Telescope (ESO VLT). Its resolution reaches 100,000
in the 1-5 μm range. Among its goals is radial velocity
measurements to study binary stars and extra-solar planets.
The term CRIRES+ was used for an upgrade to CRIRES that
was carried out in 2021, which increased its observation efficiency,
widening wavelength-range it can cover in a single observation.
