利用ZEMAX设计一个三片式物镜结构


1 利用ZEMAX设计一个三片式物镜结构(均为标准球面)

规格参数如下:

  • 35mm相机胶片
  • 50mm焦距
  • F/3.5
  • 玻璃最小中心厚度与边缘厚度4mm,最大中心厚18mm
  • 空气间隔最小2mm
  • 可见光波段
  • 光阑位于中间透镜
  • 各透镜所用材料SK4---F2----SK4

在LDE中输入初始结构,设置中间透镜为光阑面,设置各透镜所用玻璃材料类型,此时的焦距为49.7684。

初始结构

点击Gen打开General窗口,在General系统通用数据对话框中设置孔径。在孔径类型中选择Image Space F/#,并根据设计要求在Aperture Value中输入3.5.

General

由于使用35mm相机胶片,其规格尺寸为36mm*24mm,Zemax中一般使用圆形像面,因此该矩形像面的外接圆半径经计算为21.7mm,0.707像高的视场高度为15.3mm.

点击Fie打开Field Data窗口,设置三个视场分别为0mm、15.3mm、21.7mm.

Field Data

选择可见光波段,点击Wav按钮,设置Select-F,d,C(Visible),自动输入三个特征波长。

选择可见光波段

执行命令Editors----Mreit Function打开Mreit Function Editor编辑窗口,在Mreit Function Editor编辑窗口中执行命令Tools---Default Merit Function,打开默认评价函数对话窗口,选择RMS---Spot Radius--Centroid评价方法,并将厚度边界条件设置为玻璃最小中心厚度与边缘厚度4mm,最大中心厚18mm,空气间隔最小2mm。

得到三位布局图以及阴影模式如图所示。

三位布局图

以上分析说明目前系统存在球差、彗差、色差、场曲等缺陷。
