Abstract
Une post-focalisation s'obtient par utilisation de moyens de sélection de couleur dans un tube d'image en couleur constitués par une plaque métallique qui présente un grand nombre d'ouvertures et contre laquelle sont appliqués les conducteurs oblongs d'une façon isolée électriquement par rapport à la plaque, les conducteurs enjambant les ouvertures et les divisant en deux moitiés pratiquement symétriques. De plus, un tel tube d'image en couleur peut fonctionner suivant le principe de post-déviation.
