Paper Abstract

A novel method for fabricating microlens arrays (MLA) with continuous phase-relief has been proposed in this paper. It includes three main parts in details: obtaining continuous exposure on photolithographic materials by using moving mask method; fabricating continuous MLA on gelatin by enzyme treatment; replicating MLA to polymer by prepolymerize monomer injection molding techniques. The microlens has parabolic section profile and no dead area, it has the merits of high integration, high energy usage, and less chromatic aberration, especially is useful for broadband application. This method is fast and more convenient than binary optics method or laser direct writing techniques.
