I tried those code: FOR i = -0.500, 0.500, 0.1 PRINT $STR(i)," ",NEXTPRINT! This one starts from -0.5 and ends at 0.5 FOR i = -0.500, 0.500, 0.05 PRINT $STR(i)," ",NEXTPRINT ! This one starts from -0.5 and ends at 0.5 FOR i = -0.500, 0.500, 0.01 PRINT $STR(i)," ",NEXTPRINT ! This one starts from -0.5 and ends at 0.49, WHY? Thanks! Xing

Hi, I’m currently trying to trace a large amount (~1 million) of rays with very specific output position and trace their path length it takes them to reach a detector and then output the position as well as the specific path length of that beam. Currently not using scattering, but in future, I would like to extend this to scattering as well. My first thought was to create a loop that would create single rays, trace them, return the OPL through a Merit Function and then output in the end, but I assume that this would take forever to compute. Any idea how this would be done more efficiently? I’ve seen that batch ray trace might be an option, but I don’t know enough about it or other alternatives to evaluate correctly. Thank you for any help!

I don’t understand how I should set the Filter and RayDatabaseFile of the DetectorViewer in non-sequential mode. SHould I use : DetectorView = zos.system.Analyses.New_DetectorViewer() or : DetectorView = zos.system.Analyses.New_Analysis(zos.ZOSAPI.Analysis.AnalysisIDM.DetectorViewer) Then should I use : settings = DetectorView.GetSettings() and/or ? settings = zos.ZOSAPI.Analysis.Settings.RayTracing.IAS_DetectorViewer(settings) Then using : settings.RayDatabaseFilename = db_file settings.Filter = "h9" Those seems to make the analysis fail

Hello, I am working on a macro as described in the following article, but converted in Python: https://support.zemax.com/hc/en-us/articles/1500005579082-Modeling-Rotationally-Symmetric-Irregularity-RSI-with-the-API As working directly on the system, each modification saves an UNDO file and the action is repeated for each Zernike coefficient, for each surfaces, that slows down the execution. The actual way : Get the system with : TheSystem = TheApplication.PrimarySystem and work on it directly I tried to get a copy of the system with the CopySystem function, modify the copy and push it back : TheSystem = TheApplication.PrimarySystem new_system = TheSystem.CopySystem() # does work here TheSystem = new_system.CopySystem() When looking at the surface type of TheSystem, I can see that it changed correctly, however it is not applied in the Zemax main window. I used the TheSystem.UpdateStatus() function, but does not help. Ideally my goal would be to be able to make all modifications outside

How can I extract detector data using the API? And how can I be sure I'm using the correct settings?

This looks like a bug in ZOS API : when calling FindMaterialCatalog on a row of a non-sequential model with ABSORB as mateial, it returns the first catalog in the available catalog listI would except this call to return None or “”

In non-sequential mode, I am trying to automate the process of reviewing any input data that is spectral. The idea is to review how all models (in the wide sense) behave wrt wavelength in a quick way to make sure there’s nothing shady happening, using the ZOS API. For now I’m trying to review : - all coatings used, and their spectral response wrt incidence angle and wavelength - all materials used and their refractive index and extinction response wrt wavelength because given the complexity of a NSC model, the complexity of coatings definitions/catalogs, material definition/catalogs, a mistake can happen quickly. For now the idea is to review those spectral model dependencies only in a “passive” manner, using the NCE - without running a raytrace specifiicaly. If anyone has ideas or guideline on this process, feel free to comment ! :)

Hi all, I am trying to use ZOS API to assign the diffraction-based dll for the User Defined Object in Non-sequential mode. I have tried normal ‘Diffraction Grating’ object and it works good, however, for the User Defined Object, it did not work. Could anybody share some insights for me? Thank you! Part of the code for normal ‘Diffraction Grating’ object: (This works!) TheNCE.InsertNewObjectAt(1); o1 = TheNCE.GetObjectAt(1); o1.ChangeType(o1.GetObjectTypeSettings(ZOSAPI.Editors.NCE.ObjectType.DiffractionGrating)); o1.DiffractionData.Split=ZOSAPI.Editors.NCE.DiffractionSplitType.SplitByDLL; o1.DiffractionData.DLL='srg_trapezoid_RCWA.DLL'; o1.DiffractionData.StartOrder=-1; o1.DiffractionData.StopOrder=1; Part of the code for ‘User Defined Object’: (This does not work!) TheNCE.InsertNewObjectAt(1); o1 = TheNCE.GetObjectAt(1); o1.ChangeType(o1.GetObjectTypeSettings(ZOSAPI.Editors.NCE.ObjectType.UserDefinedObject)); o1.Comment = 'DiffractionGrating.DLL'; o1.DiffractionData.Split=ZOSAPI.Edito

I would like to access, through ZOSAPI, detector data which has been fitered by a filter string. I know how to access detector data through ZOSPI. And it is of course possible to view filtered data in OpticStudio by saving a trace to a ZRD file and specifiying that as the database for a detector viewer. The filter string can be applied as the ZRD is saved, or applied in the settings of the detector viewer. But I would ike to access the filtered data as it is viewed in the detector viewer, rather than the unfiltered data. Is this possible? I am actually using ZOSAPI from Mathematica, but an answer related to Python or C++ would be useful. Kind regards, David,

Following, Feature Request: ZOS-API Layouts Exports Completion | Zemax Community, I’d also advocate for making the 3 cutting plane tools from the NSC Shaded model available in ZOS API. Those cutting tools are quite efficient in visualisation, and sometimes even absolutely necessary. Now that we can export the shaded model to png easily, it’d be great to be able to enable/disable those cutting planes as well. In the same manner, having access to the Camera View would be nice:

Hi, I would like to use zpl to update my detector viewer and save it as an image.

I am using the ZOS-API in C# with 4.8.1 framework using Zemax OpticStudio 2024 R1.02 and getting an error message when running the Local Optimization tool. The error message returned from running the tool is “Input settings are invalid”. This occurs only when I load from an Archive File (.ZAR). If I load from a model file (.ZMX) then the Local Optimization tool works as expected. For the fields that I set, there are only 2; Algorithm = DampedLeastSquares and Cycles = Automatic It’s weird and I can’t understand the difference between accessing the model from an Archive would create this issue. NOTE, that I did load the ZAR file from the actual Zemax application and Optimization worked fine. If anyone has any ideas as to the issue then please let me know Thanks B.

The ray density of the spot diagram is not being updated as expected; I have tried two different methods: # spot diagramspot = TheSystem.Analyses.New_StandardSpot()spot.GetSettings.RayDensity = 15spot.ApplyAndWaitForCompletion() newSpot = TheSystem.Analyses.New_StandardSpot()print("Spot has analysis specific settings? ", newSpot.HasAnalysisSpecificSettings) # True; no ModifySettingsnewSettings = newSpot.GetSettings()newSettings.RayDensity = 15newSpot.ApplyAndWaitForCompletion() However, after being run the ray density of the spot diagram does not update as expected - any ideas?

Hi, I try to retrieve the output POP field distrubution via python. I looked in the help at IAS_PhysicalOpticsPropagation and couldn't find direct way to do it. I know I can manually save ZBF files and then load, but I need a script as I change parameters and want to retrieve the output beam. How would you advise to do so? Thanks, Leonid

Hello fellow optics enthusiasts, I’m currently working on a task where I need to ignore multiple surfaces in a Zemax optical system using the ZOS-API. At the moment, I’m using the following loop: for i in range(150, 160): surface = TheSystem.LDE.GetSurfaceAt(i) surface.TypeData.IgnoreSurface = True However, this approach seems to be quite slow. Has anyone found a more efficient way to ignore multiple surfaces at once? Any insights or suggestions would be greatly appreciated! Thanks in advance,Sebastián

Hello Everyone, What is the best way to create sag on a lens surface (one of the two surfaces would be the beginning, and then I would move to both surfaces) and parametrize it using python so that i can create wavefront maps and the changes in the wavefront maps based on the localized changed in the sag? Here is what I want to do: Create sag on a lens surface that can be parametrized (conic constant and the other asphere constants can be varied) For each combination of these parameters, evaluate the wavefront map So far, the knowledgebase articles show how to use a .dat file to induce sag on surfaces, but there is nothing about parameterization. Is there a Python example that does something similar? Or is there any other method that would make more sense? Thank you for your insights. Amit

Is there a way to access the properties of a coating in the ZOS-API? The article below shows how to access the name of the coating, but does not show how to get the properties of the coating. I’m not finding any handles that give the actual coating information. Thanks!

In the API, I make some checks on the ZMX file before running simulations. One of the checks is that at least face 0 has a coating. The API tells me there is no coating, but I can see in OpticStudio that there is a coating. Here is the object in OpticStudio: And the coating from the API: I'm certain I have the right object - why is the coating incorrect in the API? How can I check for the existence of coatings on face 0? Right now I'm using face_data.Coating not in {'None', 'NULL'}.

I am trying to develop a UDS (User Defined Surface) DLL and have been reading the excellent articles in knowledge base about this. Taking as the starting point the “us_stand.c” code for the standard surface (available in the folder /Zemax/DLL/Surfaces), I understand that Zemax provides an intercept point to the tangent plane (x0, y0, z=0) and direction cosines (l0, m0, n0) for the ray at that point. Then the real ray trace is performed in case 5 and for complicated surfaces there is no analytical solution for the ray intercept point on the surface. Hence an iterative solution is needed. What I am struggling to understand is: how do those equations in case 5 work? I thought that there would be no analytical solution to find the ray intercept point with the standard surface. However, the equations in case 5 seem to be quite simple, although I was not able to derive them. Therefore, my questions are: Is the algorithm in case 5 of “us_stand.c” implementing a closed-form analytical solution

Hi all - As the title states, I’m attempting to perform a Standard Zernike Analysis across multiple files simultaneously using the Zemax Python API and Multiprocessing (running 4 instances of Zemax). My attempt is shown below. Failures I’ve encountered include: *** FRU__delta_init(): Attempt to start when running! and UnboundLocalError: local variable 'zos' referenced before assignment I’m not sure if my approach is flawed or if I’m just attempting something that’s not allowed with Zemax or something else. Any insight you can provide would be greatly appreciated. Thanks! Also, thank you to David Nguyen for his example code on performing a Zernike Standard Analysis here. if __name__ == '__main__': import multiprocessing as mp import os import glob from ShortZernMonolith import ShortZernMonolith documents_path = os.path.join(os.path.expanduser("~"), "Documents") directory_path = documents_path + "\\SenseCheck" # Create list of TSAV*.zmx files found in folder TSAV_Files = [] for files in
