Abstract

Dispositif pour assurer un éclairement constant dans un volume donne et son application à la détermination du diamètre de particules sphériques. Ce dispositif comprend, après la source S sur l'axe du faisceau incident, un condenseur C et un premier diaphragme il placé dans le plan focal objet d'un premier objectif 12, un second diaphragme 17 placé contre ce premier objectif 12 et un second objectif 14 situé dans le plan focal image dudit premier objectif 12 et projetant dans la zone de mesure 13 l'image du premier diaphragme 11. Application à la détermination statistique du diamètre de particules sphériques opaques et transparentes.
