The Side Dual Vis-Nir Fiber Fed Spectrograph For The 10.4 M Gran Telescopio Canarias
ADVANCED OPTICAL AND MECHANICAL TECHNOLOGIES IN TELESCOPES AND INSTRUMENTATION, PTS 1-3(2008)
摘要
SIDE (Super Ifu Deployable Experiment) is proposed as second-generation, common-user instrument for the GTC. It will be a low and intermediate resolution fiber fed spectrograph, highly efficient in multi-object and 3D spectroscopy. The low resolution part (R = 1500, 4000) is called Dual VIS-NIR because it will observe in the VIS and NIR bands (0.4 similar to V 1.7 microns) simultaneously. Because of the large number of fibers, a set of similar to 10 identical spectrographs is needed, each with a mirror collimator, a dichroic and two refractive cameras. The cameras are optimized for 0.4 - 0.95 microns (VIS) and 0.95 - 1.7 microns (NIR) respectively.
