Abstract:	本論文提出一種潛望鏡式三倍光學變焦五百萬畫素手機鏡頭光學系統設計，此光學系統架構為在變焦鏡頭前置放一顆邊長6 mm之直角稜鏡，使光路轉折90方向，而使光學系統厚度為6 mm，長度為26.65 mm，可置於機身厚度為6 mm的手機裡。本變焦鏡頭設計為三群鏡組，不含稜鏡共有五片鏡片，包括三片非球面鏡片與兩片球面鏡片，其中第一群固定有兩片鏡片，第二群有兩片鏡片，第三群有一片鏡片。而光學系統初階設計為半視角為30至10.89，焦距範圍為3.142 mm至9.426 mm，光圈值為F/2.8至F/5.13。本研究使用CODE V光學模擬軟體針對變焦光學系統規格與要求，利用CODE V優化指令與巨集程式進行優化，可達到設計需求。 ;The purpose of this thesis is to present a folding type of three times zoom lens for a five mega pixel mobile phone camera. The configuration of optical system that use the right angle prism in front of the zoom lens to change the optical path of 90 result for the zoom lens thinkness of 6 mm. The zoom lens can placed in mobile phone that thinkness is 6 mm. The zoom lens has three groups. Without including the right angle prism, The zoom lens has five lenses that include three piece of aspherecal lenses and two piece of spherical lenses. The first group of zoom lens that has two piece of lenses is fixed. The second group of zoom lens has two piece of lenses. The third group of zoom lens has one piece of lens. The first order of zoom lens has a half field of view of 30o to 10.89o, a focal length range of 3.142 mm to 9.426 mm, a f-number of 2.8 to 5.13. According to specification and requirement of the zoom lens system, we use CODE V optical simulation software as a tool to the zoom lens design. To reach our requirement, we applied Macro-Plus language of CODE V to the optimization.
