Hectospec 300-Fiber Spectrograph

Modified 24-October-2007 by Doug Mink

Hardware	Hectospec is a moderate-resolution, multiobject optical spectrograph fed by 300 optical fibers. It operates at the f/5 Cassegrain focus of the 6.7-meter MMT on Mount Hopkins in Arizona. The instrument is composed of a robotic positioner and a large, bench-mounted spectrograph, joined by a bundle of 25m long optical fibers. Dual robots, dubbed Fred and Ginger, reconfigure all 300 optical fibers in just 300 seconds. [Instrument home page] [Hectospec instrument paper in PDF] [Fiber positioner paper in PDF]
