Abstract

La présente invention concerne un régleur de flux lumineux. Ce régleur comporte un support 10 monté sur un axe 12 et muni d'une pluralité de canaux 9 transparents à la lumière parallèles les uns aux autres s'étendant dans le sens longitudinal de la lumière. Les canaux 9 perméables à la lumière sont délimités par des lamelles Il opaques. Le support 9 est entraîné par l'intermédiaire de l'axe 12, par un moteur 13 qui permet de faire varier son inclinaison et de régler le passage de la lumière. L'invention s'applique aux dispositifs d'éclairage des microscopes.
