Paper Abstract

ESPRESSO is a high resolution UV-vis spectrograph that will be placed in the combined Coudé laboratory of the ESO VLT. The instrument is in its assembly phase and the Coudé optics will start to be mounted at the telescope in the first quarter of 2016. This paper describes the optics of the train and the strategies for its alignment taking into account the main constraints: accessibility, mechanical, as per built optics, tolerances and tools.
