Method for all-round coating of objects

摘要

In the application of a thin all-round coating to e.g. spectacle lenses in a rack, coating material (28) is converted from its solid state into atomized particles (34) by an electrically heated crucible within a gas chamber. The atomized particles circulate as a viscous flow within the partially evacuated chamber. Circulation of the atomized particles is promoted by active or passive means. Also claimed is a commensurate coating assembly.
