this is not easy though...... X"asfA[6K N;sm*+r 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, =duks\)O =<z.mzqu5 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......... 95W?{>
@ ~g;
For thsoe who knows it better, please have some input. I am rather curious, too!! Thanks!!
Hi, hopebox, ?DV5y|}pj RIn9(r Thanks for your reply. Really like those words “guess”, “doubt”… 2;3f=$3 Y4.Eq+$gh For your curiosity, have good luck! 0u
