Abstract
PURPOSE: To reduce non-pointal and image face bending abberation by constituting main electron lenz with small diameter pre-stage lenz and large diameter post-stage lenz where pre-stage lenz is provided indivisually for each beam while post-stage lenz is provided commonly.
CONSTITUTION: Reduction by-potential type electron lenzes Lenzs1R, Lenzs1G, Lenzs1B at the pre-stage of main electron lenz are constituted independently for each beam Br, Bg and Bb with each electrode G4R, G4G and G4B for fourth grid and third grid G3, while post-stage acceleration type by-potential electron lenz Lenz 2 is constructed commonly for each beam BR, BG, BB.
