Liquid microlens with tunable focal length and light transmission
View through CrossRef
A microfluidic design was created to allow liquid microlens to control focal length and light transmission. The focal length of the microlens was controlled by varying the volume of liquid infused into the liquid cell. The cell extruded a polydimethylsiloxane film and produced a changeable curvature. The imaging ability of the microlens was tuned by taking advantage of the phase transition of poly-N-isopropylacrylamide in the liquid. The phase transition temperature was controlled in the range of 25.6–34.5°C by changing the ion concentration.
