Claim:
1. A dynamic nanofocusing system so as to realize desired adjusting distances for focusing for the use thereof in the field of microscopy, interferometry or similar applications, the nanofocusing system comprising: a lever-transmitted coarse-adjustment piezo actuator and a frictionless guide based on an elastically deformable solid-body joint which is connected to a receiving unit that carries a body to be moved having a mass so as to realize the desired adjusting distances for the focusing; a first and a second tubular piezo shear actuator which are fixed to the receiving unit which is driven by the lever-transmitted coarse-adjustment piezo actuator; and a compensation mass; wherein the first tubular piezo shear actuator is, for its part, connected to the body to be moved and the second tubular piezo shear actuator is connected to the compensation mass.
