Abstract
A method for creating microlenses, the method includes the steps of providing a substrate having a plurality of photoactive areas; providing a photopolymerizable fluid composition on the substrate; providing a template which is transparent to photoactive wavelengths and which includes a plurality of curved surfaces that act to focus incident light onto the photoactive area; placing the template on the photopolymerizable fluid composition which causes the fluid material to spread and substantially fill the curved surfaces of the template; and irradiating light through the template and onto the photopolymerizable fluid composition for hardening photopolymerizable fluid composition into microlenses spanning the substrate.

A method for creating microlenses, the method comprising the steps of:
- (a) providing a substrate having a plurality of photoactive areas;
- (b) providing a photopolymerizable fluid composition on the substrate;
- (c) providing a template which is transparent to photoactive wavelengths and which includes a plurality of curved surfaces that act to focus incident light onto the photoactive area;
- (d) placing the template on the photopolymerizable fluid composition which causes the fluid material to spread and substantially fill the curved surfaces of the template;
- and
- (e) irradiating light through the template and onto the photopolymerizable fluid composition for hardening photopolymerizable fluid composition into microlenses spanning the substrate.
