Abstract

Dispositif pour déterminer la qualité du poli des surfaces optiques. Le dispositif comporte successivement un générateur d'un faisceau laser 6 traversant au moins une surface optique 8, 9 à analyser, une lentille convergente 10 un diaphragme 12 disposé dans un plan focal et des moyens 14 à 19 pour mesurer le rapport entre l'intensité lumineuse traversant l'ouverture 13 du diaphragme et celle arrêtée par le diaphragme. Aplication à la détermination de la qualité du poli des lames à faces parallèles.
