The instrumentation suite of the 3.5-m WIYN Telescope includes an integral field unit (IFU) called SparsePak that feeds the Bench Spectrograph. SparsePak exploits the A-omega advantage of large fibers to enable deep spectroscopic observations of low surface brightness extended sources. It contains 82, 4.7 arcsec diameter fibers arranged in a configuration with an inner core of 17 densely packed fibers, with angular extent of 24 x 39 arcsec, that are surrounded by a sparser grid of fibers subtending 72 x 71 arcsec. Additionally, 7 sky fibers are arranged approximately 25 arcsec away from the “object” grid, along 2 adjacent edges. I will describe performance characteristics of the SparsePak IFU and highlight UW science programs that are utilizing it.
