將高分子金屬複合物之薄膜應用於光學變焦模組

Abstract

離子性高分子金屬複合材料(IPMC)可以在低電壓下驅動且獲得大幅的形變量，反射式方法有折疊光路的優點因此被用在輕薄的變焦系統中， 應用在光學變焦系統中的IPMC可形變面鏡可以透過電壓改變其屈光度。聚二甲基矽氧烷（PDMS）用來作為緩衝層以改善表面粗糙度，而PDMS的表面粗糙度約為17奈米，在3福特的電壓下，IPMC可形變面鏡的屈光度可達73.8 m-1 ，我們製造了一個全反射式的相機模組，並利用兩個IPMC可形變面射鏡來達到縮放功能。縮放比約為1.6倍。

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.
