Abstract
PURPOSE: To obtain three lenses of large diameter with a less distortion for electron beams without spreading apart a distance between centers of the lenses, by constructing beam passing holes with a triple round holes and a partition electrode and providing recessed cut parts in the partition electrode.
CONSTITUTION: In face-to-face positioned plate faces of a focusing electrode G3 and an anode G4 that are the electrodes to construct a main lens, are in-line arranged beam passing holes of large diameter g31, g32, g33 and g41, g42, g43 for passing three lines of electron beams respectively on a horizontal straight line. Flat plateshaped both end edges 12, 13 of a partition electrode 11 consisting of a U-shaped metallic element installed in the focusing electrode G3 play a role of the partition plate at two places of narrowed parts in a triple round holes g3, thus constructing the virtually independent three beam passing holes g31, g32, g33. And in a similar manner are constructed the three beam passing holes g41, g42, g43.
