摘要: A carrier is disclosed for supporting an optical blank in the chuck of a lathe, for machining the optical blank into a lens. The carrier has a substantially cylindrical body formed of a machinable material. The cylindrical body has an opening at a first end thereof through which an optical blank can be inserted, and a retaining portion for securing such optical blank in place. In a preferred embodiment, the retaining portion is an annular shoulder extending inwardly at a second end of the cylindrical body.
