The DEIMOS spectrograph is a multi‑object spectrograph being built for Keck II. The paper aims to describe the major problems encountered in completing the spectrograph, focusing on optical quality and image motion. The authors analyze construction challenges, emphasizing optical quality and image motion. DEIMOS was delivered in February 2002, became operational in May, and is now about three‑quarters through commissioning, with strategies addressing problems described and overall performance meeting major goals.
The DEIMOS spectrograph is a multi-object spectrograph being built for Keck II. DEIMOS was delivered in February 2002, became operational in May, and is now about three-quarters of the way through its commissioning period. This paper describes the major problems encountered in completing the spectrograph, with particular emphasis on optical quality and image motion. The strategies developed to deal with these problems are described. Overall, commissioning is going well, and it appears that DEIMOS will meet all of its major performance goals.
