Abstract
A zoom lens is provided, which includes an electrode pattern on a substrate, and a liquid-crystal material on the electrode pattern. The electrode pattern includes a plurality of concentric ring electrodes surrounding an innermost electrode. Each of the concentric ring electrodes has an opening. A first trace extends from a first electrode out of an outermost concentric ring electrode to the innermost electrode. The first trace has greater resistance than the concentric ring electrodes and the innermost electrode. A second trace connecting the innermost electrode and a second electrode out of the outermost concentric ring electrode through the openings. The liquid-crystal material includes a liquid-crystal compound with a chemical structure of wherein R is Calkyl group, n=1 or 2, and each of X is independently H or F.
