The Spectroscopic Survey Telescope
Abstract
The authors describe the motivation for and general design of a large special purpose spectroscopic survey telescope (SST). The telescope is based on an array of 73 spherically figured segments about a meter in diameter with a radius of curvature of 26 meters making up a primary mirror with an effective aperture exceeding 7 meters. All tracking motions are in a lightweight focal surface system that can track objects for up to 40 minutes using a two element reflecting corrector for spherical aberration. The telescope has a fixed tilt to the vertical which allows access to a 48 degree strip of declination through an azimuth angle rotation. Instrumentation is coupled to the focus by means of fiber optics. Multiple object tracking over the 50 deg2 field is possible.
