[求助]關(guān)于出瞳 [復(fù)制鏈接]

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?yàn)槲沂怯眠@兩個(gè)操作符，出來的結(jié)果是錯(cuò)誤的，請(qǐng)高手賜教。 qI1JM =  

你先看看EXPP是相對(duì)于哪個(gè)面對(duì)額~

EXPP一般不是相對(duì)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. im6Rx=}E{  
>*A"tk#oR  
For example, if your first surface is Surface 1 and the last surface (image surface) is 10, you could set XsVp7zk\  
uFzvb0O`O  
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.
