SUMMARY A scanning tunnelling microscope operating with ±12 V is described. A scanning range higher than 1 μm is achieved in the three orthogonal scanning directions for that low voltage. This translator arrangement, based on the use of piezoelectric discs mounted on metallic circular plates acting like flat springs, may provide a better performance than the tube scanners or rectangular bimorphs since it allows a greater volume to be run by the tip for a given voltage.
