摘要:
A method is presented herein for manufacturing an immersed Fresnel structure. A first liquid polymer is applied to a first surface of a substrate, the substrate having a second surface that is opposite the first surface. The first liquid polymer is illuminated with light to change at least one property of the first liquid polymer and obtain a modified polymer attached to the first surface of the substrate. A second liquid polymer is applied to at least a portion of a surface of a Fresnel structure. The second surface of the substrate is applied to an outer surface of the second liquid polymer applied to the Fresnel structure to obtain a stacked Fresnel surface. The stacked Fresnel surface is illuminated with light to obtain an immersed Fresnel structure. The immersed Fresnel structure can be used as part of a near-eye display.
