Hi Chanitti,

I don’t think that there’s a built-in way to do that. If you were able to generate a profile of that beam in OpticStudio, you could use another programming langague to detect and measure that beam profile for you. In the end, you could even write your own custom analysis that would calculate this beam size within OpticStudio.

By the way, what do you call the width of a Bessel beam? Do you have a formula to share? Some people have different definitions. Have you had a look at this?

Take care,

David
