Abstract
Y. C. Ding, J. Y. Shao, and co-workers demonstrate a creative and economic method for manufacturing large-area microlens arrays (MLAs) with controllable curvature and supersmooth surfaces. On page OP 165, the production of a concave MLA is achieved by electrohydrodynamically deforming the surface of a photocurable prepolymer trapped in microhole array which has been etched onto a doped silicon wafer. The concave MLA is then used as a master to generate the convex MLA via vacuum micromoulding.
