The Visible Multi-Object Spectrograph (VIMOS) is a wide field imager and a multi-object spectrograph installed at the European Southern Observatory's Very Large Telescope (VLT), in Chile. The instrument used for deep astronomical surveys delivers visible images and spectra of up to 1,000 galaxies at a time. The Franco-Italian instrument operates in the visible part of the spectrum from 360 to 1000 nanometers (nm). In the conceptual design phase, the multi-object spectrograph then called VIRMOS included an additional instrument, NIMOS, operating in the near-infrared spectrum of 1100–1800 nm. Operating in the three different observation modes, direct imaging, multi-slit spectroscopy, and integral field spectroscopy, the main objective of the instrument is to study the early universe through massive redshift surveys, such as the VIMOS-VLT Deep Survey. VIMOS saw its first light on 26 February, 2002, and has since been mounted on the Nasmyth B focus of VLT's ''Melipal'' unit telescope (UT3).〔(【引用サイトリンク】title=VIMOS—Visible Multi-Object Spectrograph )〕 == Gallery == File:Magnificent Spiral Galaxy NGC 7424.jpg|Galaxy NGC 7424 seen by VIMOS File:NGC 5317 (also NGC 5364).jpg|VIMOS takes its first light image of galaxy NGC 5364 File:NGC 6769.jpg|A triplet of galaxies seen by VIMOS File:Phot-09a-02-normal.jpg|The Antennae Galaxies, one of VIMOS' first images File:A Pool of Distant Galaxies.jpg|The Chandra Deep Field South File:ACO 3341.jpg|VIMOS images the 500 million light years distant galaxy cluster ''ACO 3341'' File:Phot-09g-02-hires.jpg|Galaxy ''NGC 2613'', a spiral galaxy that resembles our own Milky Way File:NGC 6118 (captured by ESO’s Very Large Telescope).jpg|VIMOS sees cluster NGC 6118 at a distance of 80 million light-years File:ESO- SN 2006X in Messier 100-Phot-08b-06.jpg|Messier 100 seen in different filters by VIMOS (left) and FORS 1.
