Abstract

Composition de verre comprenant 54 à 66 % de SiO2 , 7 à 15 % d'Al2 O3 , 10 à 25 % de B2 O3 , 0,5 à 4 % de Li2 O, 3,5 à 15 % de Na2 O, 0 à 10 % de K2 O, 6 à 16 % au total de Li2 O + Na2 O + K2 O, 0 à 1,25 % de PbO, 0,1 à 0,4 % d'Ag, 0,2 à 1 % de Cl, 0 à 0,3 % de Br, 0,002 à 0,02 % de CuO et 0 à 2,5 % de F. Des pièces de 1,3 à 1,7 mm d'épaisseur présentent les propriétés photochromiques suivantes : a. à environ 25 à 30 degrés C, ledit verre passe par assombrissement à une transmission lumineuse inférieure à 30 % en présence d'un rayonnement actinique, il atteint en pâlissant une transmission lumineuse d'au moins 1,75 fois la transmission à l'état assombri cinq minutes après avoir été soustrait au rayonnement actinique, et il atteint en pâtissant une transmission lumineuse dépassant 80 % de sa transmission lumineuse à l'état clair une heure au plus après avoir été soustrait au rayonnement actinique; b. à environ 40 degrés C, ledit verre passe par assombrissement à une transmission lumineuse inférieure à 50 % en présence d'un rayonnement actinique et atteint en pâlissant une transmission lumineuse dépassant 80 % de sa transmission lumineuse à l'état clair une heure au plus après avoir été soustrait au rayonnement actinique; c. à environ -18 degrés C, ledit verre descend par assombrissement à une transmission non inférieure à 5 % en présence d'un rayonnement actinique; et d. à l'état non assombri, ledit verre présente une transmission lumineuse d'au moins 60 %. Application en lunetterie.
