First Claim
Patent Images
1. An optical device with refractive properties and diffractive properties, comprising:
- a substrate;
a first discrete relief structure disposed over said substrate, said first discrete relief structure having a curved surface to provide said refractive properties; and
one or more layers of an optically-transparent polymer material disposed over said first discrete relief pattern to define a surface curvature envelope of a second discrete relief structure, said surface curvature envelope being formed of discontinuous diffractive features to provide said diffractive properties.

Abstract
An optical device is formed of two discrete relief structures to provide refractive and diffractive properties. A first discrete relief structure has a curved surface to provide the refractive properties, and a second discrete relief structure disposed over the first discrete relief structure includes one or more layers of an optically-transparent polymer material to provide the diffractive properties. The one or more layers in the second discrete relief structure define a surface curvature envelope formed of discontinuous diffractive features that produce the diffractive properties of the optical device.
