SILFID: A Versatile Fiber-Optics Spectrograph for Faint Objects
The spectrograph SILFID has been designed for working with optical fibers, either in the “MEDUSA” mode (for studying simultaneously several point-like objects in a large field: of the order of 20′-30′), or in the “ARGUS” mode (for bidimensional spectrography of moderately extended objects:10″ to 30″, with as many as 500 independent spectra). It includes an imaging mode and could also be used as a long-slit or multi-slit classical spectrograph.
