System for manufacturing an optical lens
TL;DR: In this article, a system for manufacturing an optical lens that is configured to correct optical aberrations, including, e.g., Zernike polynomials, is described.
Patent
Method of manufacturing an optical lens
TL;DR: In this article, a method of manufacturing an optical lens that is configured to correct high order aberrations is described. But the method is not suitable for high-order optical systems.
