Abstract
This technology relates generally to methods for the fabrication of high performance lenses, in particular, lenses including a glass carrier and an at least partially transmissive layer with one or more slope facets coupled together by one of more draft facets on a surface of the glass carrier. The methods involve identifying geometric errors in the slope and draft facets to create correction factors and forming corrected slope and draft facets based on the correction factors. This technology also relates to the resulting lenses and lens arrays.
Claims25
A method for making a lens, the method comprising:
- providing a first glass carrier;
- providing a first at least partially transmissive layer on a surface of the first glass carrier;
- forming one or more slope facets coupled together by one or more draft facets on a surface of the first at least partially transmissive layer;
- identifying geometric errors in the one or more slope facets and one or more draft facets of the first at least partially transmissive layer to create correction factors;
- and
- forming corrected one or more slope facets coupled together by one or more draft facets on a surface of a second at least partially transmissive layer on a surface of a second glass carrier using the correction factors.
A lens comprising:
- a glass carrier;
- and
- an at least partially transmissive layer on a surface of the glass carrier, wherein the at least partially transmissive layer has one or more slope facets coupled together by one or more draft facets on a surface thereof, wherein the one or more slope facets coupled together by one or more draft facets are corrected slope and draft facets formed with correction factors determined by geometric errors identified in facets of a lens structure.
