(FR) REVÊTEMENTS DURS ANTI-RÉFLÉCHISSANTS
Abstract:
(EN) An article includes a substrate including a glass, glass-ceramic, or ceramic composition and a primary surface. An optical film is disposed on the primary surface. The film includes a first plurality of layers which includes diamond or diamond-like carbon and a second plurality of layers. Each layer of the second plurality of layers is arranged in an alternating manner with each layer of the first plurality of layers. The optical film includes an average photopic light reflectance of about 2.0% or less and a transmittance of about 85% or greater from about 500 nm to about 800 nm.
(FR) Selon l'invention, un article comprend un substrat comprenant une composition de verre, de vitrocéramique ou de céramique et une surface primaire. Un film optique est disposé sur la surface primaire. Le film comprend une première pluralité de couches qui comprennent du diamant ou du carbone de type diamant et une seconde pluralité de couches. Chaque couche de la seconde pluralité de couches est agencée de manière alternée avec chaque couche de la première pluralité de couches. Le film optique présente une réflectance de lumière photo-optique moyenne d'environ 2,0 % ou moins et une transmittance d'environ 85 % ou plus entre environ 500 nm et environ 800 nm.
