Hi,
I have a complex laser delivery system, with several lenses, that ultimately is a 1:1 for an array of lasers (modeled as different fields).
There is a physical aperture inside the system (for straylight purposes).
I’m trying to optimize it’s Z placement so that it’s located at a point where the combined spot size of all fields is minimal.
I’m not finding a simple way to do this in Sequential - although I assume there must be.
Any insight?
Thank you!

Hi Olieli
Footprint may help?
the question changes to how to get the footprint size in merit operand

or ray height on the aperture surface (Max REAY-Min REAY)?
Hi Yang and thank you for your reply.
I’m not sure how that helps...

I suggest you try using the extended source encircled energy feature. First, create a simple IMA file that represents your laser source array (e.g., an array of ones embedded in a background of zeros). Check it using the Extended Source Encircled Energy tool in the GUI, or the Geometric Image Analysis tool. In this case you would most likely just use Field 1 for purposes of locating the IMA file center. If satisfied with the results, then simply use the XENC operand for optimization purposes.

Jeff
