Hi, everyone,



Can you guys help me.



I would like to find out about the center of gravity of the beam on the image plane.



Is the center of gravity of the beam already calculated by Zemax and had been shown in any analyze data? If not, did I have to calculate it by myself.



Maybe there is something that I did not realized or maybe I don’t have the right knowledge about it.  I would love to know and learn.



Thank you.

Hi,



You can calculate the centroid coordinates with the Optimization Operands CENY and CENX:





The Optimize Tab (sequential ui mode) > Automatic Optimization Group > Merit Function Editor (automatic optimization group) > Optimization Operands by Category > Constraints on Real Ray Data



Best,



Berta
