Abstract

The Optical System for Imaging and low Resolution Integrated Spectroscopy (OSIRIS) is the first light instrument for the 10.4 meters Gran Telescopio de Canarias (GTC). It's a 8.5 × 8.5 arc-min visible camera; a set of grisms provides low resolution spectroscopic capability. In this contribution the accessories and mountings for alignment are presented as well as the techniques used. Also, a complete characterization of the system at laboratory for image quality, spectral and spatial resolution, and image movement, etc. are shown.
