Abstract
An iris includes a stator assembly having a frame coupled to an electrically wound, substantially annular magnetic core. The iris further includes a rotor, which is rotatably coupled to the magnetic core such that a channel is defined. A diaphragm, having a plurality of diaphragm leaves, is coupled to the stator assembly. The diaphragm leaves are pivotally arranged to form an adjustable aperture, which is substantially concentric with the channel. A portion of at least one of the diaphragm leaves is coupled to the stator assembly, and another portion of at least one of the plurality of diaphragm leaves is coupled to the rotor.
