Abstract:	本論文提出1000萬畫素手機鏡頭設計，本設計為四片塑膠非球面鏡片之鏡頭，其像方所有視角主光線角度都小於25°，而鏡頭第一面至成像面之總長度為9.96 mm，以方便於手機鏡頭所使用。在鏡頭成像品質方面，MTF在所有視場之空間頻率在120 lp/mm 以內都大於52%；橫向色差在所有視場都小於0.94 μm，比一個畫素1.4 μm還小，其橫向色差對感測器而言不容易分辨；而光學畸變與電視畸變對所有的視場都小於0.62%。在所有的非球面其模仁加工之鏡面上其斜率都小於1，即其角度都小於45°。 The paper presents 10 million pixel camera design for mobile phone, the design of the four aspheric lens of plastic, the image side’s chief ray angles less than 24° at all field, the total length from first surface to image was 9.96 mm to facilitate the mobile phone used. Imaging quality of the lens, MTF’s spatial frequencies in 120 lp / mm is over than 52% at all field lateral color is less than 0.94 μm at all field, smaller than a pixel size 1.4 μm, the lateral color issue not easy to detected in this sensor the optical and TV distortion are less than 0.62% at all field. In all aspheric mold processed the slope of the lens surface are less than 1 and the angle is less than 45 °.
