Paper Abstract

An experimental method is presented to maximize the replication quality of UV-molded micro-optical components. It is important to maximize the replication quality, because one can obtain the replicated micro-optical components with desired properties by accurate control of the shape. In the present study, a simple technique to avoid micro-air bubbles was first suggested. The effects of the UV-curing dose and the compression pressure on the replication quality of UV-molded structure were examined experimentally. Finally, as a practical application of the process design method, micro-lens arrays with diameters between 8μm and 230μm were fabricated by the present method, and the replication quality and the optical properties of the replicated micro-lens were measured and analyzed.
