Scientific paper

A multi-object instrument for spectrography in a large field is presented. It is of the arm design as MX or ARGUS. The MEFOS (Meudon-ESO Fiber Optical System) version is built to be used at the ESO 3.60 m prime focus with the triplet corrector. The FIFI (Franco-Italian Fiber Instrument) version, a copy of MEFOS, is shared between the Bologna Observatory and the Paris-Meudon Observatory and will be used, on a visitor basis, at the CFHT prime focus. The instrument carries 30 independent arms with an imaging capability on each arm. It is a modular design with its electronic implemented on each arm. The system is under control of anti-collision software and the whole instrument is driven by an PC/XT-type computer.
