I would like to analyze stray light in non-sequential mode over a range of focus travel. Scripting this seems necessary given the duration for ray tracing and the large number of focus positions needed. I’m sure this is a common task and I’m reaching out for any possible example scripts. The basic functions would beRun ray trace Save detector output (inverse gray scale, incoherent irradiance, log -10 as image file) Update Z position of object Repeat steps 1-3Everything except step 2 seems straight forward, so I’m mainly looking for help with saving detector data.My preference would be to work directly in ZPL, but can work via the API (Matlab preferred) .Thanks in advance for any help,John

I would like to analyze stray light in non-sequential mode over a range of focus travel. Scripting this seems necessary given the duration for ray tracing and the large number of focus positions needed. I’m sure this is a common task and I’m reaching out for any possible example scripts. The basic functions would be

Run ray trace
Save detector output (inverse gray scale, incoherent irradiance, log -10 as image file)
Update Z position of object
Repeat steps 1-3

Everything except step 2 seems straight forward, so I’m mainly looking for help with saving detector data.

My preference would be to work directly in ZPL, but can work via the API (Matlab preferred) .

Thanks in advance for any help,

@Oran , Thanks for your help. I’ve got the position updating and detector image saving in a loop, but I’m not finding how to initiate a new ray trace on each loop. The RAYTRACE keyword seems specific to sequential mode.

Hello John,

For step 2 look at this thread:

And step 3 would look something like

POSITION_CODE = 3  # 3 is for Z
SETNSCPOSITION 1, OBJECT_NUMBER, POSITION_CODE, NEW_POSITION

Run it through your FOR loop and that’s it.

The raytracing keyword for NSC is NSTR
