Laser demolding method |
摘要 |
An automated demolding apparatus for reliably and repeatedly mechanically separating contact lens mold portions of a mold assembly without damaging the contact lens formed there between. Before demolding, the second mold portion is irradiated by a laser beam, which is absorbed thereby to cause a substantial temperature gradient between the second mold portion and the contact lens being demolded.
