An optical wavefront modifier modifies a wavefront of an optical beam passing through the modifier. The modifier comprises a first and a second transparent electrode layer and a flat medium for modifying the wavefront depending on electrical excitation of the medium and arranged between the electrode layers. The electrode layers are provide the electrical excitation to produce a first wavefront modification of a first order of a radius in the cross-section of the beam in the plane of the medium and simultaneously produce a second wavefront modification of a second order of the radius different from the first order.
