Claim 13:
14. The corrector system of claim 11, wherein the second electrode comprises:
a second core composed of the electrically isolating material and having (i) a second inner side orientable toward the beam path and (ii) a second lateral side adjacent to the second inner side and not facing the beam path when the second inner side is oriented toward the beam path, the second lateral side separated by the distance (g) between the lateral side of the first electrode; and
a second coating composed of the electrically conductive material that forms a second outer layer of at least a second portion of the second electrode, the second portion including the second inner side and a length (l) along the second lateral side adjacent to the second inner side, wherein the second coating on the second inner side is positioned between the second core of the second electrode and the charged particle beam along the beam path when the corrector system is used in the charged particle system.
