Abstract
A tunable liquid crystal lens device is provided that uses a number of conductive elements and external contacts all located along a common side of a device housing. The device may include planar electrodes, a patterned electrode, a heating element and a sensor, which may be in different layers of the device. The device is produced as part of an array of such devices and, in addition to the devices in the array, a plurality of electrical conductive strips are used to provide high conductivity connection to conductive layers in each of the devices, thereby allowing simultaneous testing of the devices in the array.
