Title (EN) ROBUST OPTICAL FILTER UTILIZING PAIRS OF DIELECTRIC AND METALLIC LAYERS
(FR) FILTRE OPTIQUE SOLIDE UTILISANT DES PAIRES DE COUCHES DIÉLECTRIQUES ET MÉTALLIQUES
Abstract: front page image
(EN)'Corrosion' performance of an optical filter is enhanced when a relatively thick zinc-based film (30, 32 and 34) functions as a seed layer for a subsequently formed silver-based film (18, 20 and 22). At least two pairs (12, 14 and 16) of dielectric and metallic layers are included within the optical filter, where the zinc-based film is a second film of the dielectric layer and where the silver-based film is the metallic layer. The zinc-based film has a zinc content of at least 80 percent and has a thickness of at least 15 nm. In order to further improve the corrosion performance, gold may be incorporated into the silver-based film.
(FR)La performance contre la corrosion d'un filtre optique est améliorée lorsqu'un film à base de zinc relativement épais (30, 32 et 34) fonctionne comme une couche de germes pour un film à base d'argent formé ultérieurement (18, 20 et 22). Au moins deux paires (12, 14 et 16) de couches diélectriques et métalliques sont incluses à l'intérieur du filtre optique, le film à base de zinc étant un second film de la couche diélectrique et le film à base d'argent étant la couche métallique. Le film à base de zinc présente une teneur en zinc d'au moins 80 pour cent et a une épaisseur d'au moins 15 nm. Dans le but d'augmenter encore la performance contre la corrosion, de l'or peut être intégré dans le film à base d'argent.
