Abstract
The present disclosure relates to an apparatus for modifying a curvature of a thin plate optic using controlled heat and densification of portions of the optic. In one embodiment the system has a support structure for supporting the optic about a perimeter thereof, a laser configured to generate a beam having a predetermined energy, and the beam being directed at one surface of the optic. The beam heats and densifies portions of the optic to create a force on the optic. The force induces a stress produces a controlled deformation of the optic. The controlled deformation at least one of modifies a curvature of, or corrects a defect in, the optic.
