  • SYSTEMS AND METHODS FOR POLISHING FREEFORM LENSES
    Publication number: 20130148079
    Abstract: Systems and methods for polishing a lens having a freeform design cut into a surface of the lens are provided. The system may include a lap blank having a substantial inverse of the freeform design cut into a surface of the lap blank, or a conformable lap blank having an inverse of the freeform design molded into a surface of the lap blank. The system also includes a deformable pad mounted on the surface of the lap blank. The surface of the lens is separated from the surface of the lap blank by the deformable pad, and the lens and the lap blank are arranged such that the freeform design of the surface of the lens is substantially aligned with the substantial inverse of the freeform design of the surface of the lap blank.
