Hii All , How can I find out m square for final beam of multi configuation system ? POPD gives us the value for only one configuation. Right ?
Solved
M square for multi configuration system
Best answer by Sandrine Auriol
You can save the ZBF for each configuration here:
The ZBF files will be saved under {Zemax}\POP\BeamFiles.
Then you can write a macro that will add them. I have attached the macro in my previous post. It needs to be copied under {Zemax}\Macros. But here is a screenshot of the code:
Hi Tariq
Yes but you will have to use a macro.
You can sum the ZBF beam together and then calculate the M^2 of that new ZBF beam.

Hi Tariq
Yes sure. Sorry I need to retype my message as it was cleared when I post it….

Actually i am working on a system which is a 10*1 beam combiner and i need to find m square for final beam ?
The M^2 can be computed using the POPD operand data=25/26.
Look at this article to see how to use the POPD operand: https://support.zemax.com/hc/en-us/articles/1500005487221-What-is-the-size-of-my-POP-beam-
By the POPD I can only get for one configuration ? and the code is giving any output !
Yes POPD works as any merit function operand. So it is one configuration at a time.
So once you have made the sum of your ZBF, you can then define it in POP and then use POPD to evaluate the M^2 of the sum

Sounds cool, going to try . Thanks
Hi
And when I am importing file in POP , the effect in merit function ( by POPD (25)) is none.
Hi
I think the issue is that ZBFSUM only sums two ZBF files at a time. So you will have to do the sum in a loop.
Let us know if you need any help on this.
