Abstract
In some embodiments, a camera component includes an annular lens holder component having a threaded interior surface for translating rotational motion of an optics barrel component into motion along an optical axis of the optics barrel component. In some embodiments, the threaded interior surface of the lens holder component includes one or more threads complementary to one or more threads of a threaded exterior surface of an optics barrel component. In some embodiments, the optics barrel component is movably mounted on the threads of the threaded interior surface of the lens holder component for rotational motion within the lens holder component. In some embodiments, the optics barrel has a threaded exterior surface with one or more threads complementary to the threads of the threaded interior surface of the lens holder component. Some embodiments include a piezoelectric motor fixedly mounted to a base component.
