Title (EN) OPTICAL STACK
(FR) EMPILEMENT OPTIQUE
Abstract: front page image
(EN)An optical stack including an oriented polymeric multilayer optical film and a non-birefringent optical filter is described. The oriented polymeric multilayer optical film has a first reflection band with a first band edge and the non-birefringent optical filter has a first blocking band. In some cases, the first blocking band contains the first band edge and the first blocking band provides a reduction in variation of a band edge of an overall blocking band of the optical stack.
(FR)L'invention concerne également un empilement optique comprenant un film optique multicouche polymère orienté et un filtre optique non biréfringent. Le film optique multicouche polymère orienté présente une première bande de réflexion avec un premier bord de bande et le filtre optique non biréfringent a une première bande de blocage. Dans certains cas, la première bande de blocage contient le premier bord de bande et la première bande de blocage permet de réduire la variation d'un bord de bande d'une bande de blocage globale de l'empilement optique.
