Hello all!

I would like to design an Object which is a 1D array of collimated beams and look at all the beams on a single POP surface? Not discrete POP windows with one field at a time, but a single window with all beams.


Goal is to measure:

  1. Beam Width of each individual beam in X and Y
  2. Peak-to-Peak distance and Centroid-to-Centroid distance between let’s say 2 extreme beams emanating from the 1D array of collimated beams.

In other words, I would like to measure individual beam profiles of multiple collimated beams using POP (beam widths in X and Y)  and also measure the distance/separation between these beams (peak/centroid/etc.) as part of tolerance analysis?

 

How would I model this in Zemax?

 

Cheers - Asuku
