摘要
本研究利用PDMS可撓性材料製作鏡片，藉由氣壓迴路設計驅使軟式鏡片變形或曲率變化，達到變焦之功效。研究過程首先針對PDMS材料進行光學性質試驗，然後進行變焦鏡頭光學設計，並對光學設計後之鏡片參數進行模具設計與變焦鏡頭機構設計製作。最後根據PDMS軟鏡片製作、機械組裝和光學測試結果，發現裝載PDMS球面鏡片之軟式變焦鏡頭於施力0-0.02MPa時，焦距變化量可達10-15%(33.44-39.72mm)。同時得知軟式變焦鏡頭變焦能力和PDMS軟鏡片厚度與形狀有關。

This research is to develop a novel zoom lens system with a soft polymer materials, PDMS, which can be controlled by pneumatic pressure to adapt its shape and curvature to change effective focal length. Optical design of such soft zoom lens has been accessed to decide the optical specifications. After the mechanical assembly of soft zoom lens, the effective focal length of soft zoom lens with PDMS sphere lens can reach from 10 to 15% as the pressure activated from 0 to 0.02 MPa. Experimental results show that the zoom effects of the developed soft zoom lens are significantly affected by the shape and thickness of PDMS soft lens.
