Paper Abstract

A novel device of dual-tuner variable-focus microlens consisting of three kinds of liquid is put forward in this paper, whose basic structure includes a core chip sandwiched between two glass covers. The core chip is made from electric conductor to simplify the device design and the fabrication technics. The lens materials consist of three kinds of immiscible liquids, such as first conductive liquids, insulating fluid and second conductive liquid with different refractive index. Two meniscuses between every two liquids is used as optical lenses. The two-lens focal distances are tuned by changing the curvature of these two meniscuses through the effect of electro-wetting. A new liquid microscope based on EWOD is developed on the basis of the above mentioned structure, making achromatization straightforward.
