MPE contributes the MOS-unit handling the slit masks.

LUCI is built by a German consortium led by the Landessternwarte in Heidelberg. A spectrograph (also sometimes called a spectrometer) is used to disperse light from an object into a spectrum. The Near InfraRed Spectrograph (NIRSpec) will operate over a wavelength range of 0.6 to 5 microns. Like all infrared instruments, LUCI is operated at cryogenic temperatures, and is therefore enclosed in a cryostat of 1.6 m diameter and 1.6 m height, and cooled down to about -200 C by two closed cycle coolers. NIRSpec will operate over a wavelength range of 0.6 to 5 microns. Three camera optics with numerical apertures of 1.8, 3.75 and 30 provide image scales of 0.25, 0.12, and 0.015 arcsec/detector element for wide field, seeing-limited and diffraction-limited observations. A fixed collimator produces an image of the entrance aperture in which either a mirror (for imaging) or a grating can be positioned. In its focal plane area, long-slit and multi-slit masks can be installed for single- and multi-object spectroscopy. LUCI operates in the 0.9 - 2.5 µm spectral range using a 2048 x 2048 element Hawaii II detector array from Rockwell and provides imaging and spectroscopic capabilities in seeing- and diffraction limited modes. The name of the instrument was officially changed to LUCI in 2012. LUCIFER ( LBT Near Infrared Spectroscopic Utility with Camera and Integral Field Unit for Extragalactic Research) is the near-infrared instrument for the LBT. The pink area indicates the location of the MOS-unit Webb's Near Infrared Camera (NIRCam) will take a series of pictures using filters that pick up different wavelengths, and use the changes in brightness it detects between these images to estimate the redshifts of the distant galaxies. ![]() Les Lunettes opened doors five and a half years ago and its growth has been parabolic.

Shipping of both MODS 2 and LUCI 2 is planned in 2013.įig.2: Cut through the LUCI cryostat. Address: Gran de Gràcia, 6 Barcelona, Spain. First light for LUCI 1 was obtained in 2008, regular observing started at the end of 2009. The Latest NASA Released Webb Image is featured on this page. The first prime-focus camera arrived at the telescope in 2005. The beams of the two primary mirrors are combined in a near- to mid-infrared interferometer (LINC-NIRVANA) and in an optical to near-infrared interferometer (LBTI). Each of the two telescopes is equipped with three single beam instruments: a prime focus camera, an optical spectrograph (MODS), and a near-infrared instrument (LUCI, formerly LUCIFER). The LBT observing instruments split into single beam instruments receiving light from one primary mirror only, and instruments combining the beams of the two mirrors while conserving their phase relation (interferometers). The first deformable secondary was delivered in 2010, the second one in 2012. The first mirror arrived on the mountain in September 2003, the second one in September 2005. The two 8.4-meter primary mirrors have been molded and polished by the University of Arizona Mirror Lab. The telescope mount was completed in Italy and shipped to Arizona in the summer of 2002. This configuration mimimizes the instrumental background radiation and thus makes the LBT well suited for infrared observations. At the LBT, the secondary mirrors provide the deformable surfaces, therefore, in contrary to other telescopes, no additional components in the optical path are required. The essential component of an adaptive optics system is a deformable mirror which corrects the wavefront deformations in realtime. A major innovative feature of the LBT is the integrated adaptive optics (which compensates the image perturbation caused by atmospheric turbulences). Because of its binocular arrangement, the telescope achieves a resolving power corresponding to a 22.8-meter telescope. This telescope is equivalent in light-gathering power to a single 11.8 meter instrument. The LBT is a binocular telescope consisting of two 8.4-meter mirrors on a common mount (Fig. ![]() The telescope is located on Mount Graham, near Tucson, Arizona at an altitude of about 3200 m. ![]() Download a PDF of the paper titled 3D-DASH: The Widest Near-Infrared Hubble Space Telescope Survey, by Lamiya A.The LBT ( Large Binocular Telescope) is a collaboration between astronomical institutes in Germany, Italy, and the US.
