光学工程课程设计——照相物镜的ZEMAX设计

光学工程课程设计班级:T1003-3班学号:20100030305姓名:李金鑫一.光学设计软件ZEMAX 的使用 设计要求:1. 镜头镜片数小于10片2. 图像传感器(CCD)指标像素:1200×960,像元:3.8 3.8m m μμ⨯ 。

3. 物镜定焦,焦距28.0mm ,畸变 < 3.5%焦距280.2f mm mm '=±,相对孔径/1/3.5D f '=轴上点100/lp mm 的MTF 值在0.3以上,轴外0.707视场100/lp mm 的MTF 值在0.15以上, 渐晕:中心相对照度 > 65 %在可见光波段设计(取d 、F 、C 三种色光,d 为主波长)。

4.计算过程:成像面积:(1200*3.8)*(960*3.8)=4.56*3.648mm 2 对角线长度:22648.356.4+=5.84mm像高:5.84/2=2.92mm 无限远入射光线的半视场角为: 96.5)arctan(''==fy w CCD 的特征频率为:1/(2*0.038)=131.6 lp/mm有效焦距长度:'f =28mm 由于相对孔径'13.5D f =,所以8D mm =。
