Claim:
1. An optical scanning device comprising: a flexure comprising a ferromagnetic material, the flexure having a mounting portion movable in an axial direction; a first lens mounted to the mounting portion of the flexure; and an electromagnet adjacent to the flexure and spaced apart from the flexure in the axial direction; wherein: an optical path of the scanning device extends through a core of the electromagnet; the optical scanning device comprises: one or more optical elements located within the core of the electromagnet, the one or more optical elements comprising a collimating lens arranged to deliver collimated light to the first lens; a pinhole located at a focal point of the collimating lens on a side of the collimating lens away from the first lens, the pinhole comprising a tip of an optical fiber; and a mechanism for scanning the pinhole in at least one dimension transverse to the axial direction; the mechanism for scanning the pinhole comprises a second electromagnet spaced apart from a first cantilever beam in the transverse dimension, the first cantilever beam projects from a support in the axial direction, and the pinhole is mounted to the first cantilever beam, and the first cantilever beam comprises a magnetic material.
