[求助]关于出瞳 [复制链接]

在zemax的优化函数的编辑中，出瞳距离是不是用EXPP和TTHI相减啊，因为我是用这两个操作符，出来的结果是错误的，请高手赐教。 ^j}C]cq{Xg  

try to use "chief ray angle = 0" solve in "radius" column and limit the distance (mxca operand) in merit function

感谢各位的指点

可以利用TRAX TRAY REAX REAY这几个操作数根据像差的定义来描述像差（包括高阶的像差），与transverse ray fan plot类似。

You could check "Scan Type" setting under Field Curvature/Distortion curve to either scan across x or y direction. In addition, you could use Grid Distortion, which give you an overview of distortion. 6zM:p/

For coma, it normally displays as a parabolic curve in Ray Fan plot but it can be a bit complicated to analyse if you also have other dominating aberrations. Another way to look into coma is by looking at Zernike Standard Coefficeint, the term 5 and 6 correspond to coma in y and x orientation respectively. ZERN operands should help to extract these values. \zU<o~gs

However, these are only for the third order. Once you go higher order aberrations, the conversion between Seidel and Zernike becomes not so stright forward.

rzyp:谢谢啊，我知道了啊，出瞳一般是相对于像面来说的，我要得到的是出瞳到透镜最后一面的距离，所以是zemax中的出瞳距加上后工作距离才是我要的出瞳距 (2012-08-09 10:24)  $@s-OQ}

比如说我要怎么知道他们0.7071带场曲，彗差，我一直都不晓得在哪里找啊

hopebox:In ZEMAX, the position of EXIt Pupil is given relative to Image Plane.  If you wish to measure the EXIT pupil position relative to the first surface, you can use EXPP and TTHI.
For example, if your first surface is Surface 1 and the last surface (i .. (2012-08-08 22:33)  bI(8Um6m

TTHI with Surf1 = 1 and Surf2 = 10 and define EXPP in the merit function editor. Using SUMM to add the values retunred by these two operands you will be able to get the relative position of EXIT pupil to surface 1. vifw
