An optical element ( 1 ) for correcting refractive index related aberrations comprises a fluid chamber ( 5 ) which is provided with an electrode configuration ( 2,12 ) and includes a first, electrically conducting, fluid (B) and a second, non-conducting, fluid (A), and an interface ( 14 ) between the fluids, the fluids having different Abbe numbers. By applying a voltage (VO to the electrode configuration electrowetting forces are generated, which deform the shape of the interface ( 14,14 ') and determine the corrective power. |
