Abstract:
A method of providing a configuration of a system of interference filters with a visible color shifting effect, includes: a hue matching step of identifying a configuration of a first interference filter including two first metal layers and a first spacer layer therebetween, and a configuration of a second interference filter including two second metal layers and a second spacer layer therebetween, wherein the first and second filters match in hue at the first viewing angle, and the mismatch in hue at the second angle; and a lightness adjustment step which may include modifying the layer material or the layer thickness of one of the metal layers; wherein a difference in lightness at the first viewing angle between the first and second modified filters is less that a difference in lightness at the first viewing angle between the first and second filters.

Claim (Index 12):
A system of interference filters, each for providing a color shifting effect when tilted between first and second viewing angles in the presence of incident light, comprising:\n a first interference filter comprising a first reflector layer, a first absorber layer comprising an light-absorber material and having a thickness H 1 , and a first spacer layer between the first reflector layer and the first absorber layer; and, a second interference filter comprising a second reflector layer, a second absorber layer comprising the light-absorber material and having a thickness H 2  different from H 1 , and a second spacer layer between the second reflector layer and the second absorber layer, wherein an optical thickness of the second spacer layer is different from an optical thickness of the first spacer layer; wherein the first and second interference filters match in hue, chroma, and lightness at the first viewing angle, and mismatch in hue at the second viewing angle, and wherein a difference in color between the first and second interference filters at the first viewing angle is less than a difference in color at the first viewing angle between two interference filters forming a first comparison pair, different from the first and second interference filters only in that absorber layers in the two interference filters of the first comparison pair have the thickness H 1 , and is less than a difference in color at the first viewing angle between two interference filters forming a second comparison pair, different from the first and second interference filters only in that absorber layers in the two interference filters of the second comparison pair have the thickness H 2 .
