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 11):
A method of providing a configuration of a system of interference filters with a visual color shifting effect, the method comprising:\n identifying layer materials and layer thicknesses for a first interference filter comprising a first reflector layer, a first absorber layer, and a first spacer layer between the first reflector layer and the first absorber layer, and for a second interference filter comprising a second reflector layer, a second absorber layer, and a second spacer layer between the second reflector layer and the second absorber layer, wherein an optical thickness of the first spacer layer is different from an optical thickness of the second spacer layer, and wherein the first and second interference filters match in hue at the first viewing angle, and the first and second interference filters mismatch in hue at the second viewing angle; and, modifying at least one of configurations of the first interference filter or the second interference filter so as to obtain configurations of first and second modified interference filters, compromising: modifying-the layer material or the layer thickness of the first or second absorber layer or of the first or second reflector layer, or modifying the first or second spacer layer by including an additional absorber layer therewithin, 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; wherein the configuration of the system comprises the configurations of the first and second modified interference filters.
