Patent ID: 11098400

Abstract:
A machine for coating an optical article with an anti-soiling coating composition, includes a vacuum chamber (8) configured to receive the optical article, a vacuum pump (20) connected to the vacuum chamber (8), a plasma generator (11) configured to carry out a vacuum plasma treatment of the optical article, an evaporation device (10) configured to carry out a vacuum evaporation treatment of the composition for depositing it on the optical article, a control unit (2) controlling the plasma generator for removing an initial outermost anti-soiling coating of the article, controlling the evaporation device for recoating the article with the anti-soiling coating composition, being configured to causes the vacuum pump (20) to suck gases from the chamber (8) during vacuum plasma treatment and being further configured to causes the vacuum pump (20) not to suck gases from the chamber (8) during vacuum evaporation treatment.
