Description
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.
