The microlenses are generated by electrowetting effect under an electrode-less configuration and they exhibit two different regimes that are named as separated lens regime (SLR) and wave-like lens regime (WLR). The two lens regimes exhibit different optical properties. A digital holography technique is used to reconstruct the transmitted wavefront
during focusing and a focal length variation in the millimetre range is observed.
