We present details of a prototype fiber feed for use on the Anglo-AustralianTelescope (AAT) that uses a dedicated fiber-fed medium/high resolution (R >10000) visible-band spectrograph to give integral field spectroscopy (IFS) ofan extended object. A focal reducer couples light from the telescope to theclose-packed lenslet array and fiber feed, allowing the spectrograph be used onother telescopes with the change of a single lens. By considering theproperties of the fibers in the design of the spectrograph, an efficient designcan be realised, and we present the first scientific results of a prototypespectrograph using a fiber feed with 37 spatial elements, namely the detectionof Lithium confirming a brown dwarf candidate and IFS of the supernova remnantSN1987A.Comment: 41 pages, 15 figures, 3 tables; accepted by PAS
