Paper Abstract

The Optical System for Imaging and low Resolution Integrated Spectroscopy (OSIRIS) is an imaging system and a low-resolution long-slit and multi-object spectrograph for the 10.4m Spaninsh telescope GTC. OSIRIS spectral range (from 365 up to 1000 nm) and observing modes require a wide set of elements in order to provide imaging and spectroscopic capatibilities. Two tunable filters covering the full OSIRIS spectral range allow narrow band imaging with resolutions from R=300 to 1000. Twelve grisms provide spectral resolutions from R=250 through R=2500. In this contribution the design and characteristics of the tunable filters and grisms selected for OSIRIS are presented.
