Abstract: The invention provides an object holder to hold an object, comprising: a clamp side to clamp the object, wherein the clamp side is electrically conductive, at least one electrode arranged at a distance from the clamp side, and electrically isolated from the clamp side, a controller arranged to provide an electrode voltage to the at least one electrode based on a measured charge signal representative for a charge level of the object holder and/or the object in order to decrease a potential difference between an electrical potential of the clamp side and an electrical potential of the object.
