Abstract

a. Dispositif d'absorption pour supprimer la lumière diffuse, notamment sur une machine de photocomposition, b. dispositif caractérisé en ce que dans le prolongement du trajet du faisceau auxiliaire sur la face arrière de la surface partiellement réfléchissante et partiellement transparente, est disposée une structure d'absorption avec une surface concave absorbant le rayonnement du trajet du faisceau auxiliaire, c. L'invention s'applique notamment aux machines de photocomposition.
