[討論]zemax模擬高斯散射 [復制鏈接]

請教各位，對于zemax模擬高斯散射，我想控制散射角度為5度，我該如何設置散射公式中的sigma？ +2C:]

this is not easy though...... L>pP3[~DV

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 !

用下面公式： @GjWeOj]  
σ = 1.2*sin (θ/2) B4U+q|OD#  
σ:     ZEMAX 高斯散射模型sigma值； D>LdDhNn,`  
θ:     散射角半高全寬值。 X0P<ifIv  
如果散射角θ FWHM=5deg， 則σ = 1.2*sin (θ/2)=0.0523，參數(shù)設置見下圖。 eQzSWn[

多謝，這些公式有什么參考資料可以看的么？

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......... VZw(
