this is not easy though...... veq.48E] K+P:g%M 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, I UZ@n0/T QA"mWw-Ds 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......... F Bk_LEcX bf*VY&S-T For thsoe who knows it better, please have some input. I am rather curious, too!! Thanks!!
Hi, hopebox, ~jOn)jBRZ _VM()n; Thanks for your reply. Really like those words “guess”, “doubt”… bd&
