A lens positional adjustment device having a lens mounted to a moveable lens body, with the lens body including a bearing member and the lens mounted to the body to enable a laser beam to be projectable at and through the lens. A first voice coil member is mounted to the lens body and is axially offset from the optical axis of the lens. The device also includes a housing having a second voice coil member and a housing bearing with the bearing member of the lens housing being engaged with the housing bearing. The voice coil members are constructed to be one of an electrical coil winding and a magnet that engage to enable movement of the lens body relative to the housing when a current is supplied to the electrical coil winding whereby movement of the lens body relative to the housing adjusts the position of the lens.
