Abstract
The Large Synoptic Survey Telescope (LSST), ref 1, is a large (8.4M) wide-field (3.5 degree) survey telescope. The wide-field of view is accomplished by a three mirror system combined with a three lens camera. The tertiary mirror is inscribed in the primary mirror and the two will be fabricated as a single unit. The camera is located in front of the secondary mirror, which is in a conventional location. This configuration, along with the small f# of 1.23 produces a very compact system relative to similar aperture telescopes. The survey mission of the telescope requires a short slew and settling time of 5 seconds for a 3.5 degree slew. This is significantly faster than most similar aperture telescopes. Meeting this requirement is facilitated by the compact configuration which produces high natural frequencies and low moments of inertia. Maintainability also demands that the mount allow for the removal of all optical components for coating.
