Abstract

This paper presents design, fabrication, and testing of a miniature thermo-pneumatic optofluidic lens. The 3D printing creates truly 3D structures that provide a new strategy for fabricating miniature optofluidic lenses with arbitrary microchannels. The 3D printing fabricates structures successfully solves the liquid leakage issue because microchannels can be embedded in the structure. Finite element simulations are introduced to assess the uniform temperature distribution. The focal lengths under different voltages are measured. The imaging properties are characterized. The results prove the lens can be used for fine tunable focal length applications by adjusting applied voltage.
