摘要：
The present invention relates to an isotropic zero-order diffractive colour filter, to a method to manufacture an embossing tool and to a method to manufacture such a filter.
The zero-order diffractive colour 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.
