Abstract
An optical package is provided comprising a lens system, the lens system comprising an adjustable lens component, a plurality of magnetic elements, and a multi-directional lens flexure. The adjustable lens component is mechanically coupled to a lens mounting portion of the multi-directional lens flexure. The magnetic elements comprise at least one fixed magnetic element and at least one motive magnetic element. The arrangement of the fixed and motive magnetic elements relative to each other forms a first fixed/motive element pair and a second fixed/motive element pair. The motive magnetic element of each fixed/motive element pair is mechanically coupled to a motive portion of the multi-directional lens flexure. The structure of the multi-directional lens flexure and the arrangement of the fixed/motive element pairs is such that non-orthogonal repulsive or attractive magnetic force vectors generated between magnetic elements of the respective fixed/motive element pairs generate movement of the adjustable lens component through orthogonal components x, y along X and Y axes of the X-Y optical reference frame.
