Systems and methods are presented for depositing an optical coating on an ophthalmic lens substrate using at least one thermal evaporator and an ion generator. The at least one thermal evaporator is operable to resistively heat a mass-source container using an electrical current. A mass source within the mass-source container absorbs this heat, thereby producing a mass flux within a chamber. The ion generator is operable to introduce a gas source in the chamber, thereby establishing a processing environment that interacts with the mass flux. The mass flux traverses an interior of the chamber to form the optical coating on the ophthalmic lens substrate. A sequence of optical coatings may be deposited by altering between processing environments, altering between thermal evaporators, or both. Other systems and methods are presented. |
