Abstract
Several load conditions, including gravity, effects of moments due to magnet decentering, and forces applied by the central restraining membrane, have been analyzed for the 632 mm diameter, 2 mm thick adaptive secondary mirror, being developed for the MMT Telescope. All these effects can be kept well within the optical specifications.
