Abstract

An electron beam convergence device for a cathode ray tube, including means for developing a plurality of electronic rays, said apparatus also including first a beam deflection means provided with a first polarized magnet in a first orientation relative to the main axis of said tube having a magnetic field of component transverse to the trajectory of one of said rays, said first deflection means effecting a lateral deviation of said first ray in relation to its unintended trajectory and tending to make undesirable deviations from the others rays, and a second means of deflection of the beam provided with a pair of additional magnets arranged adjacent to the sides of said first magnet but on opposite sides thereof and polarized in different orientation relative to said main axis having a magnetic field of components transverse to the trajectories of said other rays, and said second means of deflection offsetting deviations from said other rays to substantially neutralize the undesirable deviations thereof due to the field of said first magnet.
