Abstract
A lens is presented in which the lens includes a substrate and an electrode layer. The electrode layer is positioned upon the substrate. The electrode layer has radially alternating rings of electrodes and resistive material. When voltage is applied across two adjacent electrodes the profile of the electric field therebetween is linear. When voltage is applied to the rings of electrodes, the optical phase profile of the lens closely approximates the optical phase of ideal spherical aberration correction.
