Abstract

An apparatus for the plasma treatment of molds (2), in particular for contact lens molds, comprises a treatment chamber (50), in which a first electrode (51) is arranged facing a carrier (1;4) for carrying the molds (2) to be treated. The carrier (1;4) forms the second electrode (52) and comprises a first metal plate (10;40) having holes (100;400) therein and a second metal plate (11;41) which is arranged spaced apart from the first metal plate (10;40), and which is connected to the first metal plate (10;40) in an electrically conductive manner (12,13;43). The molds (2) are arranged on the second metal plate (11;41) with their molding surfaces (210) facing towards the first electrode (51) and are exposable to plasma through the holes (100;400) in the first metal plate (10;40).
