A hole-patterned electrodes (HPE) liquid crystal (LC) lens is developed by using a homeotropically-aligned LC cell. Low aberration is obtained because the LC directors are well aligned along with the axially symmetrical electrical field. The optical-path difference of HPE LC lenses is less than λ/4 in all directions.
