  • 本研究致力於開發孔徑直徑3公分之介電式液態透鏡,其基本主體以兩不互溶之等密度介電溶液組成,當外加電場通過兩液體所形成之介面時,由於兩液體介電常數之差異,於介面上產生介電力,介電力造成液液介面形狀改變,進而調變介面曲率而達到調變屈光度的效果。
    當介電式液態透鏡尺度拓展為公分級,將有潛力製作成變焦眼鏡,用於補償老花眼調焦力不足。而本研究中探討公分級液態透鏡將遭遇的問題及解決方法,如厚度及重力因素;並針對眼鏡所需之屈光度調變範圍及厚度設計兩種新型結構介電式液態透鏡,製作過程遭遇的困難及製作結果將於論文中討論。
    由實驗結果得之,本論文製作之孔徑直徑3公分圓形曲面結構液態透鏡在30V驅動電壓下,可達到4D的屈光度變化量,具有應用於變焦眼鏡鏡片之潛力。
