context_page_description: The Large Binocular Telescope is an optical telescope for astronomy located on 10,700-foot Mount Graham, in the Pinaleno Mountains of southeastern Arizona, United States. It is a part of the Mount Graham International Observatory.
  When using both 8.4 m wide mirrors, with centres 14.4 m apart, the LBT has the same light-gathering ability as a 11.8 m wide single circular telescope and the resolution of a 22.8 m wide one.
  The LBT mirrors individually are the joint second-largest optical telescope in continental North America, next to the Hobby–Eberly Telescope in West Texas. It has the largest monolithic, or non-segmented, mirror in an optical telescope.
  Strehl ratios of 60–90% in the infrared H band and 95% in the infrared M band have been achieved by the LBT.
context_section_description: Some current or planned LBT telescope instruments:
  LBC – optical and near ultraviolet wide field prime focus cameras. One is optimized for the blue part of the optical spectrum and one for the red. (Both cameras operational)
  PEPSI – A high resolution and very high-resolution optical spectrograph and imaging polarimeter at the combined focus. (In development)
  MODS – two optical multi object and longslit spectrographs plus imagers.  Capable of running in a single mirror or binocular mode. (MODS1 operational – MODS2 in integration on the mountain)
  LUCI – two multi-object and longslit infrared spectrographs plus imagers, one for each side (associated with one of the 8m mirrors) of the telescope.  The imager has 2 cameras and can observe in both seeing-limited and diffraction-limited (with adaptive optics) modes. End of commissioning and hand over to the LBTO was in 2018.
  LINC/Nirvana – wide-field interferometric imaging with adaptive optics at the combined focus (in commissioning).
  LBTI/LMIRCAM – 2.9 to 5.2 micron Fizeau imaging and medium resolution grism spectroscopy at the combined focus.
  LBTI/NOMIC – N band nulling imager for the study of protoplanetary and debris disks at the combined focus. (In commissioning phase – first stabilization of the fringes in Dec 2013)
  FLAO – first light adaptive optics to correct atmospheric distortion
  ARGOS – multiple laser guide star unit capable of supporting ground layer or multi conjugate adaptive optics. End of commissioning and handover to LBTO was in 2018.
