Abstract
This invention discloses apparatus for processing one or more of a Lens Precursor, a Lens Precursor Form and an ophthalmic Lens. The apparatus provides for vapor phase processing of the subject Lens Precursor, a Lens Precursor Form and an ophthalmic Lens.
Claims1
An apparatus for processing a Lens Precursor, the apparatus comprising:
- a mandrel with an arcuate surface for supporting said Lens Precursor;
- a chamber enclosing a vapor phase environment proximate to the Lens Precursor and at least a portion of the arcuate surface of the mandrel, wherein said vapor phase environment affects at least one physical property of the Lens Precursor during processing;
- an inlet for admitting one or both of a gas and a liquid into said chamber;
- and
- a registration feature for aligning the apparatus with an external device, wherein said external device comprises a digital mirror device as a source of voxel by voxel radiation, and wherein the processing of the Lens Precursor is done in a Free Form manner on a voxel by voxel basis within said chamber.
