this is not easy though...... saY":fva 741Sd8 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, )B)ecJJ_ nHyqfd<V> 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......... OXp(rJ*bK -?nr q <3 For thsoe who knows it better, please have some input. I am rather curious, too!! Thanks!!

回楼主gmfc: kn%i#Fz 这些公式都来自 于ZEMAX用户手册有关非序列元件散射章节,稍加研究就可得出。给我发消息留下你的邮箱,我可以把推导过程发给你。 O3 NI MANG2004 #83`T&Xw*
