This micro-lens consisted of micro-fluidic chambers bonded together and sealed by an elastomeric lens membrane to which the polymer actuator has been attached. For focal length optimization, the chambers could be filled with fluids of different refractive indices. The multilayered actuator of radial shape and the variable micro-lens chip design were optimized using 2D FEM simulations. Fabrication steps included bonding of polymer actuator stack with the elastomeric lens membrane on a micro-machined silicon wafer. For a tunable micro-lens with 3 mm aperture, a tuning range in optical power between 0 and more than 15 dpt was achieved.
