在zemax的優(yōu)化函數(shù)的編輯中，出瞳距離是不是用EXPP和TTHI相減啊，因為我是用這兩個操作符，出來的結果是錯誤的，請高手賜教。 t=IM"ZgfL  

你先看看EXPP是相對于哪個面對額~

EXPP一般不是相對于系統(tǒng)的第一面嗎？

是啊，那你要的是什么？

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. >AW=N

For example, if your first surface is Surface 1 and the last surface (image surface) is 10, you could set gaJIc^O  
cuP5cL/Y  
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. 8_tMiIE-pS

謝謝啊，我知道了啊，出瞳一般是相對于像面來說的，我要得到的是出瞳到透鏡最后一面的距離，所以是zemax中的出瞳距加上后工作距離才是我要的出瞳距
