请教各位,对于zemax模拟高斯散射,我想控制散射角度为5度,我该如何设置散射公式中的sigma? L$ju~0jl)% H

this is not easy though...... <@v|~AO4~ [} %=&B I guess you need to give a try as sigma indicates the projected width of 1/e squared value of the peak irrdiance in direction cosine space...... for a normally incidence it should be around ~ cosine 85. Good luck !
Hi MANG2004, xT8!X5; 8j@ADfZ9 I am curious about your calculation, too. Plus, the definition of σ refers to 1/e^2 width not the FWHM. Even your calculation/defintion is correct. I have a doubt that it will work when the specualr incident ray angle is not normal......... ]8XIw`:f 7+J<N@.d For thsoe who knows it better, please have some input. I am rather curious, too!! Thanks!!
Hi, hopebox, j(Tk6S boIFN;Aq" Thanks for your reply. Really like those words “guess”, “doubt”… koT: r /C[XC7^4' For your curiosity, have good luck! SQf.R%cg$ }+
