Abstract

L'invention concerne un film optique comprenant une pluralité de couches de polymère A disposées sur une pluralité de couches de polymère B, de telle sorte que pour une paire de couches de polymère A adjacentes et une paire de couches de polymère B adjacentes, où les deux paires sont séparées par pas plus de 10 couches polymères dans les pluralités de couches de polymère A et B, une épaisseur moyenne de chacune des deux couches de polymère B adjacentes est supérieure à une épaisseur moyenne de chacune des deux couches de polymère A adjacentes d'au moins 5 %, et de telle sorte que pour une lumière incidente incidente à un premier angle d'incidence, une transmittance optique des pluralités de couches de polymère A et B par rapport à la longueur d'onde comprend une pluralité de régions de longueur d'onde continue à transmittance élevée et à réflectance élevée alternées. Un système optique comprend le film optique disposé entre des zones de réception de lumière.
