Abstract:
1. A mirror mounted tilt stage that comprises: (a) a stationary base unit; (b) a frame having a mirror mounted thereon wherein the mirror has a reflective surface and having a base that has an aperture or indentation on a surface thereof; (c) a single pivot member that comprises an elastic bending wire having a distal end that is attached to the stationary base unit and a proximal end wherein the aperture or indentation on the base is dimensioned to accommodate the proximal end and characterized in that the frame is suspended on the single pivot member and the proximal end pivotally supports the frame such that the frame pivots in two directions; (d) actuator means for tilting the frame that comprises four permanent magnets and each with an associated electric coil activatable by electric current wherein the permanent magnets are mounted to the frame and arranged along perpendicular axes and the permanent magnets are arranged in diametrically opposite sides; and (e) means for driving the actuator means to move the reflective surface through a predetermined range of angles in two nonparallel planes.
