Installation and coating method for ophthalmic lens

摘要

The lens coating plant, which includes coating application and polymerization posts and a conveyor, has an individual container (6) to hold each lens (2), made e.g. from metal or injected polymer and equipped with a window (13) and a lens support (3). It also has an outer seal (21) to create a sealed chamber round the lens between the container and a base (9), and systems for injecting and discharging a gas used to create an inert atmosphere for the coating process.
