ABSTRACT:
The invention provides a system and method for plasma coating of an optical lens, particularly lenses made of silicone-containing polymer. A system of the invention comprises an entry chamber, a coating chamber downstream from the entry chamber, and an exit chamber downstream from the coating chamber. The coating chamber includes a pair of spaced apart electrodes disposed therein. A system of the invention is configured in a way so that a lens may enter, pass through and exit the system without requiring the coating chamber to be repeatedly pressurized and depressurized.
