Abstract
A lens barrel for, e.g., a miniature camera or another device, includes an annular barrel, a plurality of first optical elements disposed coaxially within the barrel, an actuator device disposed coaxially within the barrel in front of the first optical elements, a front cover attached coaxially to a front surface of the actuator device, and a second optical element mounted coaxially in a central opening of a moving platform of the actuator device such that rotational movement of actuators in the actuator device causes the moving platform and second optical element to move conjointly with a purely translation movement along the optical axis of the second optical element and relative to the first optical elements.
