COSMOS - Cerro Tololo Ohio State Multi-Object Spectrograph

COSMOS and KOSMOS are nearly-identical modified versions of the OSMOS spectrograph in use on the MDM Hiltner 2.4-m telescope, and adapted for use on the 4-m telescopes at CTIO and KPNO. The design modifications, fabrication, assembly and testing were a joint effort between Ohio State and NOAO.  These instruments were built to provide a modern, high-efficiency spectrograph for the U.S. community that meets many of the scientific needs described in the ReSTAR (Renewing Small Telescope for Astronomical Research) report. Both instruments are available for community use.
