this is not easy though...... Lgr(j60s 'fo.1 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, MqKf'6z ;nx? 4f+6h 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......... M?[~_0_J lX)ZQY:= : For thsoe who knows it better, please have some input. I am rather curious, too!! Thanks!!
