Hello,still can't we save polar detector data in eulumdat/ies files with ZOS-API? Is there an alternative solution? And most importantly, can we hope that it will be implemented?Thank you!

Hi everybody,I need your advice / help for using the API.I am currently trying to run my Zemax file over the interactive mode with python. So far, I have managed with the help of the ZOS-API Syntax help and the examples presented there, but I am not getting any further at this point. The Zemax file I want to control is a non-sequential system.I would like to create a Universal 1-D Plot where I plot the value of one operand (=NSDD) in my merit function in dependence of the tilt angle of an object in my system. In the image attached at the bottom you can see the settings I would like to set over python. I am struggling with setting the field “NSC Data” with python. In the documentation under KEYWORDS-->MODIFYSETTINGS I cannot find any setting for this option: UN1_CATEGORY: Use 0 for surface, 1 for system, 2 for config.  I tried 3 for “NSC data” without success. You can find the python snippet I used below. My question boiled down:Is there a way to set the NSC category in an univ

I cannot find in the doc what are the names of the parameters in the API to change the field density and wavelength, especialy in the MODIFYSETTINGS which does not mention this type of analysisMaybe it is not implemented ?Also, the analysis results do not exihbit any data: print(analysis_results.NumberOfDataGrids)print(analysis_results.NumberOfDataGridsRgb)print(analysis_results.NumberOfDataScatterPoints)print(analysis_results.NumberOfDataScatterPointsRgb)print(analysis_results.NumberOfDataSeries)print(analysis_results.NumberOfDataSeriesRgb)print(analysis_results.NumberOfMessages)print(analysis_results.NumberOfRayData)all print 0, so is there a way to retrieve the results from this analysis ?

So far I haven't found a way to calculate many rays through to the image surface and read out the ray data on each surface.In ZPL, the "RAYTRACE hx, hy, px, py, wavelength" provides ray data on all surfaces (RAY*(surface)).Have I overlooked a solution using ZOS API?Many Thanks!Hans

Hi. I started to study ZOS-API with Matlab today. And I managed to set a specific material refractive index and get it to work without error. And My goal is to create code that can display PSF,MTF, Thorough Forcus Spot diagram and Zernike Standard Coefficients. Therfore, could you please give me some advice how to analyze them and receive their results in Matlab? import ZOSAPI.*;![endif]-->!--[if>% Set up primary optical systemTheSystem = TheApplication.PrimarySystem;![endif]-->!--[if>% AperturePupilDia = 8.0;TheSystemData = TheSystem.SystemData;TheSystemData.Aperture.ApertureValue = PupilDia / 2;![endif]-->!--[if>![endif]-->!--[if>% Lens dataTheLDE = TheSystem.LDE;% TheLDE.InsertNewSurfaceAt(2); % Surface_1 = TheLDE.GetSurfaceAt(1);Surface_2 = TheLDE.GetSurfaceAt(2);Surface_3 = TheLDE.GetSurfaceAt(3);![endif]-->!--[if>% Surf1 InfomationSurface_1.Radius = 24.397;Surface_1.Thickness = 9.915;%Setting RefractiveIndexnd = 1.52253; materialModel = Surface_1.Mat

Please do me a favor. Zemax has the function "Image Simulation". I can do this interactively. Now, I want to use "Image Simulation" to simulate 2000 frame images. Therefore, I want to use SampZOS-API Matlab programming to automatically do it.  I have learned the code ZOS-API\Sample Code\MATLAB\MATLABStandalone_04_pull_data_from_FFTMTF.m" to acquire MTF curves. Would you please tell me how to program codes. The codes can realize to load, simulate and save 2000 frame images based on "Image Simulation" moduale. It would be appreciated if you could reply me as soon as possible.

Does anyone have an example (or is there one in the zemax documentation) for altering the number of zernike terms and the terms themselves using a python API?

Hello. I am trying to get the vertex position of each optical element in terms of global coordinates. I have found I need this as I am trying to find the full X, Y, Z location for each ray when running a “CreateNormUnpol” raytrace. When I am reading the ray information, I only get values for the X & Y locations and a 0.0 value for the Z location of the ray. Is there a way to enable global position for all axes? In a similar analysis, I want to know if there is a way to run a single ray trace and get all the location and angle information at each surface as is done in the Single Ray Trace window under the Analysis tab?

I am trying to set some coordinate breaks X-Y tilts as variable using ZOS-API in Matlab.for thickness I know that the code is:Surface1.ThicknessCell.MakeSolveVariable();I tried different approaches, but nothing worked so far.

I am having an issue with the example Matlab scripts in OpticStudio. They fail to connect to OpticStudio. Here, for example is the portion of the Matlab function that connects, InitConnection FunctionIf I uncomment the success variable to define a “custom” path to OpticStudio, then the function will work; however,  the line,success = ZOSAPI_NetHelper.ZOSAPI_Initializer.Initialize();assigns 0 to success.I am curious as to why this is happening? I am running Zemax OpticStudio 2024 2.01. My installation folder for the program isC:\Program Files\Ansys Zemax OpticStudio 2024 R1.00\You can see the difference between the release number and the version that I’m running. I installed the program using the Ansys downloader.

Hi,I’m trying to extract data of Huygens PSF in Matlab through the API.I want to get the center coordinates and I thought the HeaderData will include it. But looks like the HeaderData is empty. PSF_Results = PSF_Win.GetResults();string(PSF_Results.HeaderData.Lines) ans =   1×0 empty string array The MetaData and the DataGrids seems to work fine and contains the data.Am I missing something? Is there other place that I can pull the coordinates from there? Thanks!

Type codes for modifysettings are listed in the Zemax help files under: The Programming Tab > About the ZPL > KEYWORDS (about the zpl) > MODIFYSETTINGS (keywords) However, Geometric MTF is not listed here. My question is: what are the type codes for the geometric MTF analysis window?In case these do not exist, how would I go about modifying the settings for the geometric MTF analysis window via ZOSAPI?

I need to read out the X half width and Y half width of a Detector Rectangle. The above code used to work but now it says no AttributeError: 'IObject' object has no attribute 'XHalfWidth'. Could you tell me a way to circumvent this problem. 

Recently I am developing an internal software by using c# ZOS-API dll. I have chosen .Net 8.0 for my application. After adding the refrences of ZOS-API, it gives me error due to incompatibility of frameworks. ZOS-API has been developed by using .Net framework v4.6.2. If I build my assembly with net framework 4.8, it works fine, but not supports in net 8.0. Why aren't they developing dlls with Microsoft .Net (support cross platform) instead of .Net framework? I have also seen that the headless remoting connection is taking long time. Why aren't they using modern remote procedure framework like gRPC?

Hello, I am working on designing lenses (Intraocular lens) of a power range and each power has unique merit function. I could manage to load merit function using the command below - TheMFE = TheSystem.MFE;mf3_filename = System.String.Concat(sampleDir,'\API\Matlab\MeritFunc\10.0D MF.MF');TheMFE.LoadMeritFunction(mf3_filename); In the same location I have merit functions for different power lenses. Can anyone suggest me a way how can I successfully load power specific merit function?Thanks in advance! Regards,Rahul

Title. I can easily get the entry/exit points into a GRIN lens via tracing rays to a surface using SingleRayNormUnpol() and BatchRayTrace.However, this only gives me the entry/exit points into a surface. Is there a way to get information out about the beam path within a GRIN optic via ZOS-API?As an additional note, the GRIN optic is modelled via a custom *.dll extension I developed (not a ZEMAX Gradient 1-12 surface).My alternative is to write my own GRIN raytracer for the intermediate steps.

Hello everyone,I'm trying to extract the combined Huygens Point Spread Function (PSF) of a multiconfiguration system using either ZPL or the ZOS-API. In OpticStudio, I can achieve this directly by selecting "All" in the configuration button under the Huygens PSF settings, which provides the result I need. However, I'm having trouble replicating this setting in ZPL or ZOS-API, as I haven't been able to find an equivalent command or setting to retrieve the combined PSF programmatically.Has anyone here managed to access this setting through ZPL or ZOS-API, or is there an alternative approach to obtaining the combined Huygens PSF across configurations?Thanks in advance for any guidance or examples you might be able to provide!Cheers!

We recently implemented the Geometric Image Analysis in ZOSPy 1.30. While doing so, we noticed that the setting PlotScale seems not to exposed in the ZOS-API for this analysis. Is that correct?

Need help to run through the ZOS-API C++ sample.  In zosapi.h:#import "C:\\Users\\gangs\\OneDrive - kochind.com\\Documents\\Zemax\\ZOS-API\\Libraries\\ZOSAPII.tlb"#import "C:\\Users\\gangs\\OneDrive - kochind.com\\Documents\\Zemax\\ZOS-API\\Libraries\\ZOSAPI.tlb"// Note - .tlh files will be generated from the .tlb files (above) once the project is compiled.// Visual Studio will incorrectly continue to report IntelliSense error messages however until it is restarted.But the *.tlb files were not generated after build and restart the Visual Studio, and can’t proceed.Thanks,

can I calculate and get operand IMAE without adding it to MF with python api?IMAE work as geometric image analysis? what if I need “geometric bitmap image analysis”?they have different settings and from it different efficiency values. 

Hello Everyone! During the discussions with the Zemax staff, we came across something that might be useful for everyone. This has to do with working in Python with the ZOS-API. As it is generally known, Python does not have IntelliSense in the same sense as Matlab does. The standard workaround (https://my.zemax.com/en-US/Knowledge-Base/kb-article/?ka=KA-01620 ) has been inserting break points and debugging your code to see the functions and the properties. Below is a different way that can enhance the working speed in Python. However, I should note the following. At the moment of writing this, the method works only with Python 3.8 (Tested on Python 3.8.1). The precise reason for why it doesn’t work in, say 3.7, is not clear to me, but maybe Zemax staff can provide some feedback on this? Anyway, in order to get the method to work, I required the following. As an IDE - the Visual Studio Code from Microsoft: https://code.visualstudio.com/ . Tutorial on getting started with Python

I have a couple scripts I began writing a few software versions ago on Zemax 21.2 and MATLAB 2020b. These were Zemax Zos-API MATLAB scripts that performed a large number of direct unpolarized ray traces. I have noticed that since updating my software to Ansys Zemax Opticstudio 2024 R1.03 and MATLAB R2022b there seems to be a fairly substantial performance hit. Has anyone else noticed this? Have there been changes to the way the ZOS-API functions that I need to implement in my scripts post update? 

https://support.zemax.com/hc/en-us/articles/1500005576822-Rotation-Matrix-and-Tilt-About-X-Y-Z-in-OpticStudio is misleading.OpticStudio uses degrees for Tilt About X/Y/Z, and this graphic suggests using theta_x = tilt about x. Tilt about X is in degrees, but theta_x should be in radians. If you do as the graphic suggests and plug in degrees, you'll get the wrong rotation matrix.Please let me know if I'm wrong here.

In the API command ReadNextSegment, is pathLength = optical path length or physical path length?ReadNextSegment (out int segmentLevel, out int segmentParent, out int hitObj,out int InsideOf, out double X, out double Y, out double Z, out double L, outdouble M, out double N, out double exr, out double exi, out double eyr, outdouble eyi, out double ezr, out double ezi, out double intensity, out doublepathLength) Where is the documentation on this?Is there a way to select optical or physical with this command?

I have known that using command ‘ZOSAPI.TheSystem.NCE.InsertNewObjectAt(i)’can realize the function ‘Insert Object’, then I tried some commands but still cant find corresponding one for ‘Insert Object After’.The other similar question is similar. I have known that using command ‘Det_Set1.ShowAs = ZOSAPI.Analysis.DetectorViewerShowAsTypes.GreyScale’can realize the function‘ can realize the function of setting ‘Show As’as ‘Grey Scale’, then ‘InverseGreyScale’and ‘CrossSectionRow’ dont work for corresponding functions.
