Title
(EN) ANTIREFLECTION COATING FILM AND ANTIREFLECTION COATING MATERIAL FOR OPTICAL ELEMENT AND OPTICAL ELEMENT
(FR) FILM DE REVÊTEMENT ANTIREFLET ET MATÉRIAU DE REVÊTEMENT ANTI-RÉFLEXION POUR ÉLÉMENT OPTIQUE, ET ÉLÉMENT OPTIQUE
Abstract
(EN) An antireflection coating film for an optical element is provided on a surface of a substrate of an optical material and includes first particles having a refractive index (nd) of at least 2.2 or more for the d-line and an average particle size of 10 to 70 nm, second particles of at least one of silica and sericite and having an average particle size of 1 to 11 m, a colorant of an organic substance and soluble in an organic solvent, and a resin, in which the first particle content is in the range of 10% to 35% by weight, and second particle content is in the range of 1% to 11% by weight. The antireflection coating film has a high effect of preventing surface reflection, a high effect of preventing inner-surface reflection, satisfactory absorption of visible light, and low levels of reflection and scattering in the film.
(FR) Un film anti-réflexion pour élément optique disposé sur la surface d'un substrat de matériau optique comprend des premières particules d'un indice de réfraction (nd) d'au moins 2,2 pour la ligne d et une taille moyenne des particules de 10 à 70 nm ; des secondes particules comprenant au moins soit de la silice, soit de la séricite et ayant une taille moyenne de 1 à 11 nm, un colorant fait d'une substance organique qui est soluble dans un solvant organique, et une résine dont la teneur en premières particules est comprise entre 10 et 35% en poids et la teneur en secondes particules entre 1 et 11% en poids. Le film anti-réflexion prévient très efficacement les réflexions de surface et les réflexions des les surfaces internes, a une absorption satisfaisante de la lumière visible et de faibles niveaux de réflexion et de diffusion dans le film.
