Abstract
An electronic device includes a threaded spacer and a biasing element to reduce backlash. The threaded spacer includes a thread end point that is offset from the thread start point of the carrier frame. The offset thread ending and starting points create a gap between the threaded spacer and the carrier frame. The biasing element applies a force to the threaded spacer, thereby reducing the backlash between the lens and the carrier frame, while at the same time allowing the lens to be rotated for focus adjustments.
