ABSTRACT:
A variable-wedge rotating-disk attenuator for use in an ophthalmic endoilluminator is disclosed. The attenuator includes a wedge attached to an axle. The size of the wedge can be adjusted over a variable angle as measured through an arc of the wedge. The axle to which the wedge is attached rotates such that the wedge rotates around a pivot defined by the axle. The variable-wedge rotating-disk attenuator is located such that it affects the intensity of a light beam transmitted into an eye.
