Abstract
Plastic ophthalmic lenses are coated with a scratch-resistant coating using a spin coating process. The lenses are separated from lens mold pieces, and the lenses are routed through a coating system where the lens coating in applied. A conveyor moves the lens mold pieces toward an inspection station while the corresponding lenses are moving through the coating system. The operation of the lens coating system and the conveyor are coordinated so that the coated lens and the lens mold pieces from which that lens was made are delivered as a group to the inspection station.
