An optical lens, comprising:
- a transparent substrate, and
- at least one HOE-capable polymer layer on the transparent substrate,
- wherein the at least one HOE-capable polymer layer forms a holographic optical element,
- wherein the holographic optical element is formed by a spatially resolved exposure of the HOE-capable polymer layer,
- wherein the spatially resolved exposure is based on control data that comprises an intensity and a phase of the spatially resolved exposure, and
- wherein the control data is determined depending on a geometry of the transparent substrate.
A method for producing an optical lens comprising an HOE-capable polymer layer, wherein the HOE-capable polymer layer is configured to form a holographic optical element, wherein the method comprises:
- coating of a transparent substrate of the optical lens with a precursor of the HOE-capable polymer layer;
- converting the precursor that is on the transparent substrate, to obtain the HOE-capable polymer layer, and
- performing a spatially resolved exposure of the HOE-capable polymer layer to form the holographic optical element,
- wherein the performing of the spatially resolved exposure comprises:
- obtaining geometric data comprising a geometry of the transparent substrate of the optical lens;
- and
- based on the geometric data, determining control data comprising an intensity and a phase of the spatially resolved exposure,
- wherein the spatially resolved exposure is performed based on the control data.
