Abstract:
1. A method for manufacturing optical lenses using a substrate including a first layer, a second layer and a third layer, comprising the steps of: forming a plurality of lens surfaces on a surface of the first layer of the substrate; forming a respective lens holding section for each of the lens surfaces, each respective lens holding section holding a lens region including the lens surface for which the respective lens holding section is formed, and an edge section around the lens surface, said step of forming a respective lens holding section for each of the lens surfaces including removing the third layer, with the exception of sections of the third layer that correspond to the lens holding sections for the lens surfaces, until the second layer is exposed at a rear surface of the substrate; and separating respective optical lenses defined by the respective lens regions from the substrate after completing the lens holding section forming step.
