Abstract

A new faint-object spectrograph was designed and built around the capabilities of fiber optics. This instrument, the Norris Spectrograph, is designed exclusively for the Cassegrain focus of the Hale Telescope. There are 176 indpendently positionable fibers, each with an aperture 1.5 arcsec in diameter. These 176 probes cover a field of view of diameter about 20 arcmin. The output ends of the fibers are collimated with a spherical mirror, dispersed using a normal reflection grating, and focused onto a 2048 x 2048 CCD using all-transmissive optics. The peak overall efficiency of the instrument will be in excess of 10 percent.
