Editing ESO 3.6 m Telescope (section)

== Instruments ==

Since 22, the ESO 3.6&nbsp;m telescope has hosted HARPS, the [[High Accuracy Radial Velocity Planet Searcher]] and NIRPS, the Near Infra Red Planet Searcher. HARPS is a fibre-fed high resolution [[Echelle grating|echelle spectrograph]] dedicated to the discovery of extrasolar planets. Other instruments on the telescope, now decommissioned, include:<ref>{{cite web|url=http://www.eso.org/sci/facilities/lasilla/telescopes/3p6/index.html | title = The ESO 3.6m Telescope | access-date = 2011-05-26}}</ref>
* '''CES''': is a spectrograph that provides a resolving power of up to 235,000 in the 346–1028&nbsp;nm region.
* '''EFOSC2''': the ''ESO Faint Object Spectrograph and Camera (v.2)'', is a very versatile instrument for low resolution spectroscopy and imaging.
* '''TIMMI-2''': the ''Thermal Infrared MultiMode Instrument'' dedicated to the 3–25&nbsp;[[μm]] spectrum.
* '''ADONIS''': is the acronym for ''Adaptive Optics Near Infrared System'', and was a second-generation [[adaptive optics]] system for the astronomical community.<ref name=Zirker2005/> More than 40 peer-reviewed scientific articles were  published based on this instrument data.<ref name=SIMBAD_ADONIS/> ADONIS is the final version of diverse Adaptive Optics (AO) prototypes named Come-on and Come-on +. It was offered in its final version in October 1996 as an official [[ESO]] instrument,<ref name=RoussetBeuzit1999/> then decommissioned in 2001. ADONIS was the first AO system offered to a large community of astronomers.
