PROCESS FOR TRANSFERRING A COATING ONTO A SURFACE OF A LENS BLANK

摘要

A process for transferring a coating onto at least one optical surface of a lens blank which comprises : providing a lens blank having at least one geometrically defined surface ; providing a support having an internal surface bearing a coating and an external surface ; depositing on said geometrically defined surface of said lens blank or said coating a pre-measured amount of a curable glue ; moving relatively to each other the lens blank and the support to either bring the coating into contact with the curable glue or bring the curable glue into contact with the geometrically defined surface of the lens blank ; applying a sufficient pressure onto the external surface of the support so that the thickness of a final glue layer after curing is less than 100 micrometers ; curing the glue ; and withdrawing the mold part to recover the lens blank with the coating adhered onto its geometrically defined surface.
