    Abstract: 本篇論文針對一個三百萬畫素的變焦手機鏡頭做雜散光分析與改善。使用光學軟體LightTools,為手機鏡頭加上機構組件,再以多個角度的光源入射模擬,觀察在成像面上雜散光的平均照度與照度圖。並對於雜散光依光線行進路徑的差別分類後提出鍍膜、使用塑膠不透明元件以及選擇非球面鏡片的CA(clear aperture)外部分做出鋸齒形狀的改善方法。模擬出改善的結果後,以成像面上的雜散光平均照度值和照度圖做出效率的比較與討論。 This paper analyses and suppresses the stray light for a 3 mega pixel and 3x zoom lens of the mobile phone. Established the fabrication components to the zoom lens and observed the average illumination and the illumination chart on the sensor for source incidence from many angles by using LightTools. Classified the stray light to route and coating, blackened, and changed the shape of the CA for aspherical lens are the corrected ways for suppression. After simulated by using LightTools, compared the average illumination and the illumination chart on the sensor and the efficiency.
