Abstract
The present invention relates to an isotropic zero-order diffractive color filter, to a method to manufacture an embossing tool and to a method to manufacture such a filter. The zero-order diffractive color filter comprises diffractive microstructures and a wave-guiding layer, wherein the diffractive microstructures possess a short range ordering over at least four times the period of the microstructures, and the diffractive microstructures possess a long range disordering over length scales of more than 100 μm.
