ANISOTROPIC OPTICAL DEVICE AND METHOD FOR MAKING SAME

The present invention relates to a new optical component comprising an anisotropic diffuser (5,10) with patterned anisotropy; and means (9, 11, 14, 16, 17, 20, 21, 30, 32) for providing a colorshift observable upon changing viewing angle (6) and/or changing angle of incident light (2). It also relat...

Zusammenfassung:	The present invention relates to a new optical component comprising an anisotropic diffuser (5,10) with patterned anisotropy; and means (9, 11, 14, 16, 17, 20, 21, 30, 32) for providing a colorshift observable upon changing viewing angle (6) and/or changing angle of incident light (2). It also relates to methods for making such an optical component and uses of such optical components as security elements with a very high level of security.
