Paper Abstract

New technologies make it possible to cast, polish, and support large light-weight mirrors with f/ratios faster than f/2.0. These new technologies have dramatically lowered the cost of construction of ground-based telescopes, and accordingly several telescopes with apertures of 8-10 meters are now under construction. Some of these telescopes are being optimized for fiber spectroscopy of one to a few hundred objects during a single exposure. The required design characteristics and the properties of the best commercial fibers currently available are discussed. Applications of fiber spectroscopy to such problems as the mapping of distant galaxies, the search for extra-solar-system planets, and the measurement of stellar pulsations are briefly described.
