Popis:	CRIRES, a pre-dispersed CRyogenic Infrared Echelle Spectrograph, provides a resolving power λ/ Δ λ ≈ 10^5 (or Δ v ≈ 1.5 km,s-1 per pixel) between 1000 and 5000 nm (56–315, THz) at the 8m ESO VLT-UT 1. CRIRES is a unique instrument, at least with respect to its spectral resolution, its detector format and the spatial resolution, due to an integrated adaptive optics system. Remote insertion of gas cells to measure high precision radial velocities is possible. Some specifics of the calibration of this instrument will be described.
