摘要

一般光學元件多採用射出成形或熱壓成形的製作方式，在製造程序上過程需要較昂貴的模具製作與設備投入且製造時間長，但卻無法預測實際的光學設計結果，只能以光學模擬分析軟體初步預測其光學元件成形後的光學效益。
本論文以導光與集光元件為例提出一個快速的光學元件製作方法，在導光模組的設計為雙邊對稱結構且導光板底部v-cut結構為30角度；在集光模組的設計為透鏡層曲率半徑為3mm，厚度d=2.0mm，導光層的光柵方向為雙邊方向之結構，本研究提出利用表面平整度接近光學等級的壓克力元件結合3D列印技術製作母模，並以聚二甲基矽氧烷(PDMS)製作模仁，配合利用紫光壓印成型成功製作出光學元件，利用此新的方法，可以大幅降低在光學元件開發中所損耗的時間與成本。

Injection mold or hot pressing has been usually used to produce optical components, and it not only needs more expensive molds or equipment but takes longer time to manufacture as well. However, due to these difficulties, we are hard to make an actual optical component and only can use optical analysis software to stimulate its performance.
In this study, the light guided component and the light condenser component are taken as examples; we propose a new fast fabrication method for these optical devices. In the light guiding module design, the bilateral structure is adopted and the V-cut angle underneath the light guided plate is 30°. In the condenser module design, the curvature radius of the semi-cylindrical PMMA lens is 3 mm and the thinness is 2.0 mm, and the light guided layer is a bilateral direction. The proposed fabrication method combined the PMMA component with a surface roughness near to optical grade and 3D printing technology to fabricate the master mold. Then, PDMS is used to replicate the mold and UV-imprint technology is used to successfully fabricate the optical components. By this method, we can reduce the time and cost of making optical components.
