Abstract

Filtre à infrarouges (10, 110, 210) réalisé en tant que structure stratifiée comprenant une pluralité de couches dont l'épaisseur est sensiblement uniforme. Les différents aspects de réalisation de l'invention (10, 110, 210) comprennent des premières couches (12, 112, 212) relativement épaisses et interposées avec des deuxièmes couches (16, 116, 216) relativement minces par rapport aux premières couches. Les deuxièmes couches ont généralement une épaisseur optique d'un quart de longueur d'onde pour une longueur d'onde accordée particulière, tandis que les premières couches ont généralement une pluralité d'épaisseurs optiques d'un quart de longueur d'onde. L'invention décrit des procédés de fabrication des filtres, y compris les processus de meulage et de polissage visant à obtenir l'uniformité d'épaisseur souhaitée desdites couches.
