The correction element is fixedly mounted in the housing and moveable therewith. The piezo elements are supported by a member having a first portion and a second portion. The first piezo element is mounted to the first portion of the member and to said housing, and moves the housing in a first direction. The second piezo element is mounted to the second portion of the member and to a base, and moves the housing in a second direction substantially perpendicular to the first direction.
