Hi all,

I am facing an issue when using the Image Simulation tool via the ZOS-API. The goal is to vary a certain variable in a loop (in this case the object distance), perform each time an image simulation, and save the image with a specific name to a file. However, I notice that the previous images are always overwritten when a new image is saved.

This is the simple MATLAB code that I am using in the main body:

sampleDir = 'D:\Zemax OpticStudio\';

testFile = System.String.Concat(sampleDir, '\Test_ImageTelecentric_Issue.zos');

TheSystem.LoadFile(testFile,false);

TheSystem = TheApplication.PrimarySystem;

TheLDE = TheSystem.LDE;

zline = 0;

surface = TheLDE.GetSurfaceAt(zline);

zvec = =1100,1500]; %variable object distance

for z = zvec

surface.Thickness = z;

index = 3; %existing Image Analysis window with correct settings

im_analysis = TheSystem.Analyses.Get_AnalysisAtIndex(index);

im_settings = im_analysis.GetSettings;

im_settings.OutputFile = ='z',num2str(z),'.png']; %change file name according to variable

im_analysis.ApplyAndWaitForCompletion(); %save image

TheSystem.Save();

end

Although I seem to change the OutputFile before running the analysis, the previous image is always being overwritten:

The ZEMAX archive file is found in attachment.

I would be very glad if someone could point out what the issue could be.

Thanks,

Indy
