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? S d -+a wVX0!y6 [attachment=31154]

this is not easy though...... tc Z~T
C5?M/xj 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, !ywc). ]e =W=%!A\g 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......... "lt[)3* iD~s, For thsoe who knows it better, please have some input. I am rather curious, too!! Thanks!!
Hi, hopebox, QK\z-'&n @{G(.S Thanks for your reply. Really like those words “guess”, “doubt”… 53c6dl Fei$94a For your curiosity, have good luck! L [^e<I s]qfLC MANG2004 $uqlJG#`
