9 July 2008An overview of instrumentation for the Large Binocular Telescope
An overview of instrumentation for the Large Binocular Telescope is presented. Optical instrumentation includes
the Large Binocular Camera (LBC), a pair of wide-field (27' × 27') mosaic CCD imagers at the prime focus, and
the Multi-Object Double Spectrograph (MODS), a pair of dual-beam blue-red optimized long-slit spectrographs
mounted at the straight-through F/15 Gregorian focus incorporating multiple slit masks for multi-object spectroscopy
over a 6 field and spectral resolutions of up to 8000. Infrared instrumentation includes the LBT Near-IR
Spectroscopic Utility with Camera and Integral Field Unit for Extragalactic Research (LUCIFER), a modular
near-infrared (0.9-2.5 μm) imager and spectrograph pair mounted at a bent interior focal station and designed
for seeing-limited (FOV: 4' × 4') imaging, long-slit spectroscopy, and multi-object spectroscopy utilizing cooled
slit masks and diffraction limited (FOV: 0.5' × 0.5') imaging and long-slit spectroscopy. Strategic instruments
under development for the remaining two combined focal stations include an interferometric cryogenic beam combiner
with near-infrared and thermal-infrared instruments for Fizeau imaging and nulling interferometry (LBTI)
and an optical bench near-infrared beam combiner utilizing multi-conjugate adaptive optics for high angular
resolution and sensitivity (LINC-NIRVANA). In addition, a fiber-fed bench spectrograph (PEPSI) capable of
ultra high resolution spectroscopy and spectropolarimetry (R = 40,000-300,000) will be available as a principal
investigator instrument. The availability of all these instruments mounted simultaneously on the LBT permits
unique science, flexible scheduling, and improved operational support.
