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:
- generous slit length spanning 16.6 arcmin on sky
(vs. 8 arcmin for LRIS)
- large 8k×8k detector mosaic featuring eight
MIT/Lincoln Labs CCDs
- advanced, closed-loop flexure compensation system achieving
image stability of ±0.25 px over 360° of instrument
- wide spectral coverage (up to 5000 A per exposure)
- high spectral resolution (up to R≈6000)
- high throughput
- convenient IDL-based data reduction pipeline
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.
