碩士 === 國立中央大學 === 照明與顯示科技研究所 === 103 === 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.
