Abstract
A focus adjustment module is disclosed and includes a first optical element disposed along an optical axle, a guiding track unit, a guiding unit and a controller. The guiding unit includes a holder for the optical element to be assembled thereon and a flexible member to connect to the holder. The flexible member includes an inner section to connect to the holder, an outer section and a middle controlling section. The controller moves along a control path intersecting the optical axle. The middle controlling section is sustained in a non-deformed state non-parallel to the control path. When moving from the initial position to the control position, the controller moves from the outer section to the middle controlling section to force the middle controlling section to become deformed and to link to the optical element and move it between the origin and the focus adjustment point along the optical axle.
