Abstract
The Gemini-North Multiobject Spectrograph (GMOS) includes a powerful capability for integral field spectroscopy - the first to be installed and used on an 8-10m telescope. GMOS is switched to this mode by the remote insertion of an integral field unit (IFU) into the focal plane in place of the masks used for multiobject spectroscopy. With 1500 lenslet-coupled fibres, it provides a total field of view exceeding 50 square arcseconds, including a separate field dedicated to background subtraction. We describe the design, construction and testing of the IFU and present performance results obtained during commissioning.
