Abstract

The Deep Extragalactic Imaging Multi-Object Spectrograph (DEIMOS) is a powerful multi-object spectrograph that is optimized for taking spectra of faint-object populations densely distributed on the sky. The spectrograph saw first light at the Keck II telescope on June 3, 2002, and has been commissioned during the summer. This paper will summarize the basic performance characteristics of DEIMOS, including image quality, number of spectra, throughput, and flexure. As of this writing, all major performance goals appear to have been met. DEIMOS is the work-horse instrument of the DEEP2 distant galaxy redshift survey.
