Abstract

A method for manufacturing an optical element includes forming an optical element unit comprised of an optical material such as glass and having an outer shape of a regular triangle or a regular hexagon, arranging a plurality of optical element units two-dimensionally on a substrate so as to have a structure imitating a molecular structure of graphene or a carbon nanotube, and processing the substrate on which the plurality of optical element units are mounted into a desired surface shape.
