Abstract

a. Dispositif pour réfléchir le trajet d'un faisceau auxiliaire dans le trajet d'un faisceau principal, notamment dans une machine de photocomposition. b. Dispositif caractérisé en ce que, pour compenser l'astigmatisme d'une plaque réfléchissante, comportant la surface partiellement transparente et partiellement réfléchissante, est disposée sur le trajet du faisceau principal convergent ou divergent, une plaque de compensation est disposée sur le trajet du faisceau principal, plaque qui est décalée d'un second angle égal au premier angle par rapport au rayon principal du trajet du faisceau principal, mais toutefois, autour d'un second axe orienté perpendiculairement par rapport au premier axe. c. L'invention s'applique notamment aux machines de photocomposition.at. Device for reflecting the path of an auxiliary beam in the path of a main beam, in particular in a photocomposition machine. b. Device characterized in that, in order to compensate for the astigmatism of a reflecting plate, having the partially transparent and partially reflecting surface, is arranged on the path of the converging or divergent main beam, a compensation plate is arranged on the path of the main beam , plate which is offset by a second angle equal to the first angle with respect to the principal radius of the path of the principal beam, but however, about a second axis oriented perpendicularly to the first axis. vs. The invention applies in particular to photocomposition machines.
