Abstract

Dispositif optique comportant une couche texturée L’invention vise un dispositif optique (2) et un procédé de fabrication correspondant, le dispositif comprenant : une couche texturée (4) comprenant une première surface présentant des premières macro-texturations (10) ; et un support (6) comprenant en surface une couche optiquement active (8) intercalée entre la couche texturée (4) et le support (6), la couche optiquement active (8) étant une couche diffractive ou une couche réfléchissante. La première surface de la couche texturée (4) est assemblée par lamination avec le support (4) de sorte que la couche optiquement active (8), disposée entre la couche texturée (4)et le support (6), est déformée par les premières macro-texturations (10) pour y former des deuxièmes macro-texturations (11) conformes auxdites premières macro-texturations (10). Figure pour l’abrégé : Fig. 2.
