                                    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.
