[0197] well-founded Figure 6 The focusing device used for focusing of the structure shown and the focusing device is installed on a model IT5000 Image Engine available from Hand Held Products, with a 5.88mm focal length, 6.6F# and a micro 36-inch micro fixed best focal length three-lens imaging lens combination. A driver from ARTIFICIAL MUSCLE INCORPORATED ("AMI") was used, based on the design of the MLP-95 or MSP-95 autofocus elastomer driver available from AMI. After constructing the focusing element, various voltages were applied to the flexible electrodes of the actuation device, the results are summarized in Table C below:
