Simulation and characterization of tunable achromatic micro-lenses

Simulation and measurements of achromatic variable-focus multi-chamber micro-lenses are presented. By using three liquid-filled chambers with well-defined dispersion behavior, separated by highly elastic silicone membranes, this achromatic optical system can be tuned in focal length by adjusting the pressures inside the chambers. Tunable achromatic micro-lenses are thus feasible.
