Abstract

L'invenzione riguarda un metodo e dispositivo per guidare la luce su vaschette in un fotometro. Su ciascuna delle vaschette disposte in una fila, viene consecutivamente guidata luce attraverso un disco oscuratore mobile (8) provvisto di una fessura (10) per ciascun percorso luminoso. Così la luce passando attraverso la vaschetta adiacente non interferisce nella misurazione.
