This study presents packaged microscale liquid lenses actuated with liquid droplets of 300-700 mu m in diameter using the dielectric force manipulation. The liquid microlens demonstrated function focal length tunability in a plastic package. The focal length of the liquid lens with a lens droplet of 500 mu m in diameter is shortened from 4.4 to 2.2 mm when voltages applied change from 0 to 79 V-rms. Dynamic responses that are analyzed using 2000 frames/s high speed motion cameras show that the advancing and receding times are measured to be 90 and 60 ms, respectively. The size effect of dielectric liquid microlens is characterized for a lens droplet of 300-700 mu m in diameter in an aspect of focal length. (C) 2010 American Institute of Physics.
