Abstract
(EN)
A color selective, anti-reflective optical coating has a substrate (42), a first layer (44) and a second layer (46). The first layer (44) has an index of refraction that is 25 % to 39 % greater than an index of refraction of the substrate (42). The first layer (44) has a width of between 12.31 nanometers and 13.41 nanometers. The second layer (46) has an index of refraction that is between 1 % and 17.5 % less than the index of refraction of the substrate (42). The second layer (46) has a width between 118.32 nanometers and 130.78 nanometers. When the color selective, anti-reflective optical coating is applied to a head lamp lens (40), it significantly increases the output of the head lamp (20) and has a distinctive tint.

Traitement antireflet à sélectivité de couleur possédant un substrat (42), une première couche (44) et une deuxième couche (46). La première couche (44) possède un indice de réfraction de 25 % à 39 % supérieur à un indice de réfraction du substrat (42). La première couche (44) possède une largeur située entre 12,31 et 13,41 nanomètres. La deuxième couche (46) possède un indice de réfraction de 1 % à 17,5 % inférieur à celui du substrat (42). La deuxième couche (46) possède une largeur comprise entre 118,32 nanomètres et 130,78 nanomètres. Quand on applique ce traitement antireflet au verre (40) d'un projecteur de véhicule automobile, il augmente considérablement la puissance du projecteur (20) et possède une teinte distincte.
