Abstract
Ionic polymer metal composite (IPMC) can be operated at low voltage and get large deformation. The reflective method is utilized in thin zoom system for the advantage of folded optical path. IPMC deformable mirror which used in reflective zoom system can change its optical power by bias voltage. Polydimethylsiloxane (PDMS) is used as the buffer layer to improve surface roughness. The surface roughness of PDMS layer is about 17 nm. Optical power of IPMC deformable mirror can reach to 73.8 m-1 diopter by 3 V. We fabricate the total reflective camera module and use two IPMC deformable mirrors to achieve zoom function. The zoom ratio is about 1.6 times.
