The electrode arrangement a disc-shaped substrate, e.g. glass, silicon, an electrode carrier (1), and at least two electrodes (3). The substrate is connected to a voltage source to form a voltage potential between the substrate and another disc-shaped substrate. The two electrodes are joined to the electrode carrier and contact the substrate approx. at a point. The electrodes are mechanically movable independently of one another in a direction mainly normal to one substrate plane.
