Abstract

L'invention a pour objet une cellule de photométrie. La cellule comprend deux demi-miroirs M 1 et M2 , un miroir M tronqué, la portion tronquée étant remplacée par une optique L travaillant en transmission, et un miroir M 3 conjugué de M1 par rapport à l'optique L. Les pupilles d'entrée E et de sortie S sont conjuguées l'une de l'autre par les miroirs et l'optique L. Application à la mesure de la turbidité des liquides et à la détection des polluants.
