Export detector data oin a for loop with ZPL

Question

Hi,

I am trying to run non-sequential sequence in a loop, for which I change a parameter and save the detector data for each loop. The text tab should allow me to export the irradiance data at each coordinate, but I am a little uncertain how I can grab detector 1 and 2, then save the data as text files as for example data_d1_01 and data_d2_01, data_d1_02 and data_d2_02,..etc. Any suggestions appreciated. My experience with ZPL is limited.

My attempt:

update ALL
FILENAME$ = "data_xtilt"+ $STR(xtilt) + "_tiltY_" + $STR(ytilt) + ".TXT"
savewindow 1, H:\_work\ZEMAX\+FILENAME$
savewindow 2, H:\_work\ZEMAX\+FILENAME$

This got an error “ERROR in SAVEWINDOW: Window 1 does not support text”

A few things I would change about your code:

If your xtilt and ytilt are integer whole numbers, I would use FORMAT .0 to make sure the $STR() only prints an integer. If these are not integer whole numbers, I would not use them in the filename since they will add extra periods or commas which could lead to invalid filenames
If possible, I would avoid saving to an external drive. Although the H:\ drive might be mounted to the same CPU, I’ve see issues with connecting to external or network drives
I would make sure the filename isn’t too long. OpticStudio tends to “clip” strings at 255 characters so if your filename is too long, it won’t save
You need to have your actual filename as a string literal, so you need to use double quotes.

The following should work:

update ALL
FORMAT .0
FILENAME$ = "data_xtilt"+ $STR(xtilt) + "_tiltY_" + $STR(ytilt) + ".TXT"
savewindow 1, "C:\_work\ZEMAX\" + FILENAME$
savewindow 2, "C:\_work\ZEMAX\" + FILENAME$ ! note this will overwrite WIN 1
