Abstract
Dispositif pour dévier un faisceau électronique par exemple dans un tube d'enregistrement d'images. Le dispositif comporte une culasse annulaire en matériau magnétique, munie d'au moins deux paires de noyaux diamétralement opposés, orientés vers l'intérieur et entoures de bobines de déviation. L'extrémité intérieur de chaque noyau est munie d'une pièce polaire sous forme de segment d'anneau, lesdites pièces polaires entourant l'espace de déviation. Pour définir de façon très précise et reproductible la forme des champs de déviation engendrés, chaque bobine se trouve, vu depuis ledit espace, entièrement derrière la pièce polaire correspondante, tandis que les espaces entre les pieces polaires sont suplombés d'intercalaires en matériau non magnétique. Application aux caméras d'images de télévision en couleur.
