摘要

由於目前台灣光學廠普遍面臨到高階照相手機鏡頭設計與製造間有蠻大的落差，且開發失敗率高。雖然在光學設計階段設計人員已經將光學系統最佳化及敏感度分析，但是對光學系統設計的問題幾乎沒有那個設計是絕對完善的。經由光學基礎理論及製程之變異因子了解，並使用田口式實驗法研究，協助製造優劣勢及設計之間取得平衡且用最經濟之方法尋找最佳製程，加速開發時程，提升競爭力。
本論文主要利用光學軟體建立模擬分析模型與田口式實驗法探討高畫素照相手機鏡頭之空氣間隔、鏡片中厚、偏心、面型等控制因子並評估製程能力後選擇重要之控制因子及以MTF值為品質特性，進行田口式實驗法之控制因子最佳化，並因應光學透鏡輕量微小化之需求，鏡片材質採以塑膠材質進行開發，且鏡頭結構為4P( Plastic lens)之非球面鏡頭。進而將設計理論誤差量及製造困難度降至最低並以最經濟方式找出較佳控制因子組合，完成符合未來發展趨勢之高畫素照相手機鏡頭，可做為高畫素照相手機鏡頭設計開發時之研究參考方向。

The optical factory in Taiwan are having make cell phone lens problems that the very large gap between design and manufacture of high-resolution cell phone lens, and have the development of high failure rate. Although the optical designer has the best of optical systems and optical sensitivity analysis in the design phase. But the optical system design almost is not absolutely perfect. Our main discussion will focus on how to understand the basic optical theory and make optical lens of process ,and use of Taguchi Method ,then we can find strengths and weaknesses in making of high-resolution cell phone lens and find a balance between the design and the manufacture. Through most economical Ways to find the best process, then the development schedule and Competitive strength improved .
In this thesis our main discussion will focus on how to use optical analysis software to create simulation model and use Taguchi Method to investigate the centering tolerance ,thickness tolerance , centering error ,surface form tolerances.etc of high-resolution cell phone .Then we will assess control factors , process capability and select important control factors for MTF value of quality characteristics. We can achieve the most optimal design to use Taguchi Method .And design to use aspheric lenses of polycarbonate, and use lens structure to 4P (the 4 Plastic lens) for response to miniaturization of optical lens. The amount of theoretical error will be designed and manufactured to minimize the difficulty .We can find the most economic ways and the best combination of control factors. Then we will complete with the future development trend of high-resolution cell phone lens. As a reference of future development tendency in making of high-resolution cell phone lens.
