Paper Abstract

This paper addresses a set of problems accessible via the technology of photopolymers. Though most interest in micro-optic fabrication centers around the older technology of melted photoresist and the much newer area of binary optics, much can be learned from the area of photopolymers of the graded index type. Recent advances in the technology of the DuPont materials for example, make possible the fabrication of novel micro-optic systems. We examine the manufacture of micro-lens arrays using contact and other forms of lithography. The relative merits of simple refractive optics and graded index optics are discussed. This work has been applied to the formation of specialized diffusion screens for image projection and the advantages are pointed out in the discussion.
