The optics of OSIRIS, a versatile first generation imager/spectrograph, for the 10.4-m Gran Telescopio Canarias (GTC), has undertaken its manufacturing phase. Brief descriptions of the design characteristics and expected performance are given. Current advances in a relevant optical study (throughput) are summarized as well as the status of manufactured lenses. A comparison with similar instruments for 6.5-m to 10-m class telescopes is performed, based on the instrument pupil size, collimator focal length, angular magnification, required field of view (FOV) and Lagrange Invariant. We finish with the compliance matrix of the top-level requirements, showing that OSIRIS represents a so far unique scientific opportunity of tunable imaging in this telescope class.
