Paper Abstract

Many of the popular techniques for the manufacture of microlenses do not offer proper control over the shape of the lens produced. This applies in particular to the melting of photoresist, to graded index lenses produced by ion exchange through a hole in a mask and to photothermal techniques. Although it is possible to influence the process by optimising some of the process parameters it is not in the true sense possible to control the final result. Two techniques which do offer proper control are binary techniques and "photosculpture". The purpose of this paper is to describe a simple variation of photosculpture applied to the manufacture of arrays of microlenses.
