Abstract
A system for enhancing lens preparation which allows for error compensation to provide nearly error-free lens fining and/or polishing. The system employs a flexure to allow three degrees of freedom for a lens being prepared. The system also employs a Hall effect circuit board to monitor movement of the flexure to account for error, provide feedback to a controller so that compensation for such error can be effected and so that proper force may be maintained. The flexure and the sensor feedback subsystem enable nearly error-free lens surfaces.
