CES - Coude Echelle Spectrometer

General Information
[The Very Long Camera mirror and the Main Collimator of the CES]

The CES is ESO's highest resolution spectrograph providing a resolving power of up to 235,000 in the 346 - 1028 nm region.

It is a bench-mounted echelle spectrograph, fed through an optical fiber mounted at the f/8 Cassegrain focus of the 3.60m telescope. Read more...
