Method for producing optical lens

摘要

A method for producing an optical lens includes: forming a mark outside a lens region set in a lens substrate, the mark being adapted to perform position alignment; pattern-forming a masking layer above one principal surface of the lens substrate while controlling formation position of the masking layer with the mark as a reference, the masking layer having an aperture at a predetermined position in the lens region; performing a selective process with respect to a surface exposed from the bottom of the aperture of the masking layer by performing a process from above the masking layer; and removing the masking layer from above the lens substrate to form a processed pattern by the selective process on the side of the one principal surface of the lens substrate.

1. A method for producing an optical lens comprising the steps of:
forming a mark outside a lens region set in a lens substrate, wherein the mark is adapted to perform position alignment; pattern-forming a masking layer above one principal surface of the lens substrate while directly controlling formation position of the masking layer to the lens substrate with the mark as a reference, wherein the masking layer has an aperture at a predetermined position in the lens region; performing a selective process with respect to a surface exposed from the bottom of the aperture of the masking layer by performing a process from above the masking layer; removing the masking layer from above the lens substrate to form a processed pattern by the selective process on the side of the one principal surface of the lens substrate; and forming a light transmissive material film above the processed pattern.
