Abstract: A securing structure for an optical piece is disclosed and which comprises: a hub portion; a surrounding portion connected to the hub portion; a plurality of recess structures formed or otherwise provided in at least one of the hub portion and the surrounding portion and which are at least partially open on at least one side; and a rib structure that at least partially separates the plurality of recess structures. The structure is capable of use with an apparatus for securing and clamping optical lenses (e.g., spectacle lenses) requiring edge-machining.

Abstract: An apparatus for coating the surface of a lens includes a carousel having a central hub and a plurality of arms. A drive shaft is mounted to each arm, with a magnetic clutch and a lens holder being operatively attached to the drive shaft. The carousel is configured to be raised, rotated, and lowered into a series of workstations for processing the lens in a predetermined sequence. A workstation has associated therewith a spin drive attached to a reciprocating arm assembly. The spin drive includes a magnetic clutch which may be coupled to the magnetic clutch of any one of the arms on the carousel, such that a rotation generated by the spin drive is transferred to the drive shaft, and the lens holder. The arm assembly is capable of being extended and retracted to selectively engage and disengage the carousel.
