| titleOfInvention | Correction of image defects caused by perturbations of the rotational symmetry with annular apertures |
| abstract | A stigmator for the electrical compensation of image defects in electron optical systems working with hollow beams and annular apertures in which a cylindrically shaped middle electrode, limited at its front faces by two metallic annular diaphragms, is closely arranged behind the aperture diaphragms within the lens field free space in the path of the beam, the middle electrode being of varying diameter and being surrounded by two sector shaped electrode ring system. |
