摘要: A method and system for facilitating focusing of a miniature camera are disclosed. One or more lenses can be attached to a MEMS stage. The MEMS stage can be moved by a Lorentz actuator. The MEMS stage can be configured to limit movement of the lens(es) to a single degree of freedom to inhibit misalignment thereof with respect to an imaging sensor. The stage can be biased to a predefined position thereof, e.g., for focus at infinity. A metal cover can inhibit electromagnetic interference and can limit movement of the lens(es).

摘要: A method and system for limiting the motion of components such as the optics of a camera are disclosed. The system can comprise a stage and a snubber assembly for controlling motion of the stage in six degrees of freedom. For example, the snubber assembly can permit movement in one translational degree of freedom while substantially limiting motion in the other five degrees of motion so as to facilitate focusing and/or zooming of a camera while inhibiting misalignment of the optics and while providing some protection against shock and vibration. Such motion control can be achieved while mitigating costs associated with precision manufacturing of the snubber assembly.
