Paper Abstract

We describe the procedures adopted to realize the fiber unit for feeding the near IR multi-object spectrometer GOHSS. Since a scarce literature is available on this subject, all the steps of the fabrication processes are explained and documented through a detailed illustrative material: in particular the polishing methods of the fiber ends are addressed along with the criteria for evaluating the achieved results; the preparation and application of the ferrules; the matching with the input micro-lens; finally, the laboratory tests to measure the focal ratio degradation of each fiber are presented aiming also to certify the quality of the realized device.
