ABSTRACT:
A camera having a housing, an imaging array positioned in said housing, and a lens assembly is disclosed. The lens assembly includes a fixed portion attached to the housing and a moveable portion connected to the fixed portion by a threaded coupling. The lens is positioned in the moveable portion to image a scene on the imaging array. The lens is separated from the imaging array by a distance that changes as the moveable portion is rotated relative to the fixed portion. The moveable portion includes a gear for applying a torque to the moveable portion such that the moveable portion moves relative to the fixed portion. The gear is preferably a spur gear. During the assembly of the camera, the gear is turned via a second gear such that the position of the lens is moved to a predetermined desired position.
