A curing apparatus () includes a housing () having a loading portion () open to ambient atmosphere, a curing portion () having a curing chamber () with a controlled atmosphere, and a transition portion () extending between the loading portion () and the curing portion (). A carrier () is movable between the loading portion () and the curing chamber () via the transition portion (). The curing apparatus () further includes at least one ultraviolet radiation source () operative for transmitting ultraviolet radiation into the curing chamber (). The transition portion () includes a plurality of baffles () protruding from a sidewall () of the transition portion () and configured for minimizing mixing between the ambient atmosphere and the controlled atmosphere during movement of the carrier () between the loading portion () and the curing chamber ().

Inert ultraviolet curing apparatus

A spin coater that can be used to apply multiple coating compositions over an optical substrate, is described. The spin coater includes, a coater bowl configured to collect excess coating material expelled from an optical substrate being coated, a rotatable chuck configured to receive and rotate the optical substrate in the bowl during coating, a plurality of coating reservoirs, each containing a coating material, and an indexable coating reservoir platform containing the plurality of reservoirs and configured to index a selected reservoir into a dispensing position above the coater bowl. The spin coater can include or have associated therewith at least one curing station, in which each curing station is independently configured to cure at least partially at least one applied coating material. Each curing station can include at least one of a thermal curing station, a UV curing station, and/or an IR curing station.

Spin coater for applying multiple coatings to an optical substrate

Methods and apparatus for coating optical articles, such as optical lenses, are provided. In one aspect, an optical article is placed in a holder and a sheet of coating material is discharged from a nozzle, such as from a fan coater nozzle, onto the optical article to form a coating on the optical article.
