DEIMOS (DEep Imaging Multi-Object Spectrograph) is a visible-wavelength, faint-object, multi-slit imaging spectrograph in operation at the Nasmyth focus of the Keck II telescope since 2002. DEIMOS was designed and built at UCO/Lick Observatory under the leadership of Principal Investigator Sandra M. Faber and Project Manager Dave Cowley. Notable features of DEIMOS include: Available observing modes include direct imaging, long-slit spectroscopy, and multi-slit spectroscopy of 100+ resolved targets per mask in conventional mode or 1000+ point-source targets per mask with narrow-band filters.
