|
| DESCRIPTION |
The Optical System for Imaging and low-Intermediate Resolution IntegratedSpectroscopy (OSIRIS) of the Gran Telescopio Canarias (GTC) is an imager andspectrograph for optical wavelengths. Wavelength range coverage is 0.365 - 1.05microns; total field of view is 7.8 x 8.5 arcminutes for direct imaging and 7.5x6.0arcminutes for multi-object spectroscopy.OSIRIS has a number of operating modes. Imaging modes include: broad, medium, andnarrow band imaging with various filters; fast photometry; and frame transferphotometry. Spectroscopic modes include long-slit spectroscopy and multi-objectspectroscopy.
