ESO 3.6 M Telescope - Instruments

Instruments

Since April 2008, the only instrument on the ESO 3.6m telescope is HARPS, the High Accuracy Radial Velocity Planet Searcher. HARPS is a fibre-fed high resolution echelle spectrograph dedicated to the discovery of extrasolar planets. Other instruments on the telescope, now decommissioned, include:

  • CES: A spectrograph providing a resolving power of up to 235,000 in the 346 - 1028 nm region.
  • EFOSC2: The ESO Faint Object Spectrograph and Camera (v.2) to give its full name, is a very versatile instrument for low resolution spectroscopy and imaging.
  • TIMMI-2 Thermal Infrared MultiMode Instrument dedicated to the 3 micron to 25 micron
  • ADONIS, an acronym for ADaptive Optics Near Infrared System, was a second-generation adaptive optics system for the astronomical community. More than 40 peer-reviewed scientific articles were published based on this instrument data. 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, then decommissioned in 2001. ADONIS was the first AO system offered to a large community of astronomers.

Famous quotes containing the word instruments:

    “The universe appears to me like an immense, inexorable torture-garden.... Passions, greed, hatred, and lies; law, social institutions, justice, love, glory, heroism, and religion: these are its monstrous flowers and its hideous instruments of eternal human suffering.”
    —Octave Mirbeau (1850–1917)

    “The form of act or thought mattered nothing. The hymns of David, the plays of Shakespeare, the metaphysics of Descartes, the crimes of Borgia, the virtues of Antonine, the atheism of yesterday and the materialism of to-day, were all emanation of divine thought, doing their appointed work. It was the duty of the church to deal with them all, not as though they existed through a power hostile to the deity, but as instruments of the deity to work out his unrevealed ends.”
    —Henry Brooks Adams (1838–1918)

    “I lay my eternal curse on whomsoever shall now or at any time hereafter make schoolbooks of my works and make me hated as Shakespeare is hated. My plays were not designed as instruments of torture. All the schools that lust after them get this answer, and will never get any other.”
    —George Bernard Shaw (1856–1950)
