Abstract:
An optical device, preferably for use in security devices and documents, comprising an arrangement of wavelength dependant optical phase, and optionally amplitude, modifying optical elements on a first surface of a substrate, each of the optical elements being in the form of an optical antenna and configured to produce a local phase change to reflected and/or transmitted electromagnetic waves, the arrangement configured such that the combined action of each of the optical elements produces a pre-defined optical effect on reflection and/or transmission observable by a viewer when the arrangement is illuminated by an external electromagnetic source.

Claim (Index 25):
A method of manufacturing the optical device of the security document of  claim 1 , including the steps of:\n preparing a shim having an inverse profile to a required profile of the arrangement of optical elements; applying to a surface of a transparent substrate a radiation curable ink; embossing the radiation curable ink with the shim, and curing the radiation curable ink, thereby forming the arrangement of optical elements.
