CARMENES. II: optical and opto-mechanical design

摘要

CARMENES is a fiber-fed high-resolution échelle spectrograph for the Calar Alto 3.5m telescope. The instrument isbuilt by a German-Spanish consortium under the lead of the Landessternwarte Heidelberg. The search for planets aroundM dwarfs with a radial velocity accuracy of 1 m/s is the main focus of the planned science. Two channels, one for thevisible, another for the near-infrared, will allow observations in the complete wavelength range from 550 to 1700 nm. Toensure the stability, the instrument is working in vacuum in a thermally controlled environment. The optical design ofboth channels of the instrument and the front-end, as well as the opto-mechanical design, are described.© (2012) COPYRIGHT Society of Photo-Optical Instrumentation Engineers (SPIE).
