Liquid tunable double-focus lens fabricated with diamond cutting and soft lithography

摘要

With the use of diamond cutting processes, namely turning and shaping, followed by soft lithography with polydimethylsiloxane, a liquid tunable double-focusing lens is fabricated. Data from a mechanical profiler verified that the dimensions of the features of the lens device adhere well to designed values. In addition, atomic force microscopy results show that this method of fabrication is able to produce multiple replicas of the lens device with a high-quality surface finish that is suitable for optical purposes. Lastly, the tunability of the lens is demonstrated, with experimental results agreeing well with simulation results.
