Abstract

To reach a better production sequence and an increased quality for plasma polymerization coatings and evaporation coatings on both sides of optical lenses, it is suggested to proceed with the deposition of the layers within an especially suitable apparatus configuration where the plasma polymerization coating is deposited simultaneously on both sides of the lenses.
