Abstract
A method for manufacturing an anti-reflective coating on a surface of an optical component includes the steps of placing a moth eye structure material in apertures of a stamp; placing the stamp on the surface of the optical component such that the moth eye material is in contact with the surface of the optical component; and removing the stamp after the moth eye structure material adheres to the surface of the optical component to create an anti-reflective coating on the surface of the optical component.
Claims18
A meta lens based on an optical element, the meta lens comprising:
- an optical element comprising a substrate having an optical surface;
- and
- a plurality of uniformly spaced projections of a moth eye structure material adhered to said substrate and projecting from said optical surface, wherein said moth eye structure material forms an anti-reflective coating of moth eye structure on said optical element.
A method for manufacturing a diffractive coating on a surface of an optical element, the method comprising the steps of:
- placing a layer of diffractive structure material on an optical surface of the optical element;
- rolling a stamp having apertures of a moth eye structure on a cylinder over the layer of diffractive structure material such that a moth eye structure is impressed onto the layer of diffractive structure material on the optical surface of the optical element;
- and
- removing the stamp after the stamp is rolled over the layer of diffractive structure material, wherein the moth eye structure impressed onto the layer of diffractive structure material creates a diffractive coating on the optical surface of the optical element.
