An experimental method is presented to maximize the replication quality of UV-molded micro-optical components. It is important to maximize the replication quality to obtain the replicated micro-optical components with the desired properties by accurate control of the shape. We suggest a simple technique to avoid micro air bubbles. The effects of the UV-curing dose and the compression pressure on the replication quality of UV-molded structures are examined experimentally. Finally, as a practical application of the process design method, microlens arrays with diameters between 30 and 230 /im were fabricated by the presented method, and the replication quality and the optical properties of the replicated microlens are measured and analyzed.
