Abstract
Official abstract text for this publication.
Systems, devices, and methods for embedding a diffractive element in an eyeglass lens are described. A method of embedding a diffractive element in an eyeglass lens includes applying a protective layer to a diffractive element, applying an interface layer to the protective layer, and applying a lens layer to the interface layer. The interface layer and the lens layer are each comprised of a resin material that hardens when cured. The interface layer is of a shape and thickness that adheres well to the protective layer after the interface layer is cured. The lens layer is of a shape and thickness that achieves the desired component shape of the lens after the lens layer is cured.
First claim
Opening claim text (preview).
1 . An eyeglass lens for use as a transparent combiner in a wearable heads-up display, the eyeglass lens comprising: an inner layer comprising a diffractive element; a protective layer that encapsulates the diffractive element; an interface layer that encapsulates the protective layer, wherein the interface layer comprises a resin material; and a lens layer that encapsulates the interface layer, wherein the lens layer comprises the resin material, and wherein the interface layer provides adhesion between the protective layer and the lens layer. 2 . The eyeglass lens of claim 1 wherein the protective layer includes a surface physically coupled to the interface layer and a surface physically coupled to the inner layer, and wherein the surface of the protective layer that is physically coupled to the interface layer has a higher surface energy than the surface of the protective layer that is physically coupled to the inner layer. 3 . The eyeglass lens of claim 1 wherein the diffractive element comprises a photopolymer material. 4 . The eyeglass lens of claim 1 wherein the protective layer comprises a polycarbonate material. 5 . The eyeglass lens of claim 1 wherein both the interface layer and the lens layer are respective thermally-annealed layers. 6 . The eyeglass lens of claim 1 wherein the diffractive element includes at least one holographic optical element. 7 . The eyeglass lens of claim 1 wherein the diffractive element is curved.
