A simple technique for the replication of micro-optical elements is presented. Elastomeric material is used to realize a negative mold of the original optical element and UV-curing adhesive is used to make the replicated copy. Replicated elements, such as refractive and diffractive micro-optical elements, are produced. The refractive microlenses have a diameter of 970 µm and a height of 79 µm...
