Abstract

Optical fibres have been extensively used at ESO to link telescopes to spectrographs. The last two developments included the preparation of the fibres for the HARPS and FEROS instruments in La Silla Observatory. The HARPS fibre bundle uses a high efficient scrambler for precise measurements of radial velocities (< 1 m/s). The FEROS fibre micro-lenses were updated to match the 2.2 m telescope with emphasis in optimizing the efficiency. This paper describes the features and performances of these fibres.
