LUCI Overview

The LUCI (LBT Utility Camera in the Infrared) instruments are almost identical NIR instruments, operated at cryogenic temperatures, which provide imaging, longslit spectroscopy, and MOS spectroscopy over a 4 arc-minute square field of view. The principle differences between the instruments are the cut on wavelength (0.89 μm in LUCI1 and 0.95 μm in LUCI 2, due to slight differences in the dichroic dewar entrance window) and the grating complement (each LUCI has one unique grating). They are mounted at the front Bent Gregorian f/15 focal stations of the LBT, and were designed and built by the LUCI consortium, which consists of Landessternwarte Heidelberg, MPE, MPIA, and Astronomisches Institut der Universität Bochum. LUCI1 is located on the left (SX), and LUCI2 on the right (DX).

The LUCI User Manual goes in depth into the use and capabilities of LUCI1 and LUCI2.

Available Modes

LUCI1 and LUCI2 are currently available in all seeing-limited modes.
Diffraction-limited imaging with LUCI1 is also offered in a shared-risk mode. For more information, see here. It is expected that full AO performance with LUCI1, and diffraction limited imaging and spectroscopy with LUCI2, will become available in the course of 2017B.

Once fully commissioned, the complete compliment of observing modes will include Seeing Limited and ground-layer AO (LUCI+ARGOS) modes. In addition, imaging and long slit spectroscopy will soon be offered in Diffraction Limited (LUCI+FLAO) mode.
