Abstract

We devised a fabrication method to produce plano-convex microlenses from a film composed of a photopolymerizable monomer, such as cinnamic acid derivatives, and a binding polymer, such as polymethylmethacrylate. The method, shown in Fig. 1, consists of three processes: coating, in which a film is formed on a glass substrate; selective exposure, in which microlenses are produced in the film using a photolithographic technique; aftertreatment, in which the shapes of the lenses are fixed by exposing the film to UV light.
