Paper Abstract

We present in this paper experimental data on fibres and scramblers to increase the photometrical stability of the spectrograph PSF. We have used round, square, octagonal fibres and beam homogenizers. This study is aimed to enhance the accuracy measurements of the radial velocities for ESO ESPRESSO (VLT) and CODEX (E-ELT) instruments.
