Paper Abstract

This paper wants to address the opto-mechanical stability of the Codex instrument pending onto vibration environment. CODEX is a study for an high resolution spectrograph for the European ELT. In particular the aim of the work is a preliminary verification of the instrument performances if mounted at the E-ELT Folded Nasmith location. Hence Dynamic environment of the Coudé and the folded Nasmith locations were alternatively applied to the optical layout to verify the image performances in terms of image displacements and FWHM deformations. In addition damping strategies has been verified for the improvement of the performances.
