Hi All,I’ve been trying to write a Python Interactive Extension with the ZOS-API. Having started with the boilerplate generated through the GUI at Programming > Python > Interactive Extension, I appended the following code at the end of the generated file:# Insert Code Hereimport typingpsfWindow = TheSystem.Analyses.New_HuygensPsf()settings = typing.cast(psfWindow.GetSettings(),ZOSAPI.Analysis.Settings.Psf.IAS_HuygensPsf)field = settings.Fieldfield = typing.cast(field, ZOSAPI.Analysis.Settings.IAS_Field)print(str(field.GetFieldNumber())) When I run this (having clicked on the Interactive Extension button as per the documentation), the following gets printed:Found OpticStudio at:   %sc:\program files\zemax opticstudio                       Connected to OpticStudio                                                          Serial #:  L118546   Traceback (most recent call last):                                                File "C:\Users\dshteinbok\Documents\Zemax\ZOS-API Projects\P

Is it possible to do a ZOS-API Interactive Extension with Excel VBA?I’ve been able to do a standalone with examples from this forum.  This works:    Set TheApplication = TheConnection.CreateNewApplication()    Set TheSystem = TheApplication.CreateNewSystem(SystemType_Sequential)This does not work (get the VBA error message “Object variable or With block variable not set” for the second line which seems to say that TheApplication is not being Set properly):    Set TheApplication = TheConnection.ConnectAsExtension(0)    Set TheSystem = TheApplication.PrimarySystemI’ve also been able to do an Interactive Extension with MATLAB from the boiler plate code (similar to above) generated by OpticStudio … just can’t seem to get it to work in Excel.Thanks.

Hi,Does anyone know how to pull the point space information under surface sag → text (using Matlab)? I can successfully pull SagResults.GetTextFile but couldn’t find the point space info under that, I appreciate the help in advance.  

Hello, I have some old DDE code and currently Zos api is used as a dynamic link. But for older version of Zemax, do we only need to use DDE or Zos api can be used regardless of the version of Zemax we use?

Hello!Long time fan of, and short time developer using the Raytrace.dll for fast batch ray traces in sequential mode. I have not tested it yet, but was wondering if the BatchRayTrace ray data returned accurate ray data for sequential systems that employ a non-sequential component? The application that I am thinking of is for a non-sequential group with a single segmented mirror, and it is convenient to set up the segmentation in a non-sequential group to alter individual mirror segment positions without using a very large number of multi-configurations. Thanks!Jaren

I am running dozens of non-sequential ray traces in a row, and I'd like to know of any tips for optimizing speed. My current process: Calculate a path for a moving source/detector. For each point in the path, move the source/detector a few mm (currently either a rectangle or STL detector) and run a ray trace. Aggregate the results at the end. I saw that you were considering using GPUs (in particular RTX cards) for ray tracing. Any progress on that? ETA? Maybe a beta build of OpticStudio that I can use? It would take a while to run 56 traces at 500k rays each on an 8k triangle STL. 🙂 Maybe I'm missing a simple way that this can be 10x faster.

I am trying to take a known set of Fringe Zernike Coefficients, and insert them into a zemax optical system model as a Zernike Fringe Phase surface. I’ve gotten as far as being able to insert the surface and set it as a Zernike Fringe Phase type, but I haven’t had any success with entering coefficient values into the LDE. I’ve tried LDE.GetSurfaceAt(28).GetCellAt(14).DoubleValue = valuewhere value is a float, but it throws an exception saying that a Double was expected and it got a string. I’ve also tried to just return a value that I’ve typed in manually, but had no success that way either. Can anyone point me in the right direction here? It seems like it should be simple with entering numbers into the LDE, but nothing has seemed to work so far.  Thanks

I’m working on a code to see how the Strehl ratio of our system changes over different iterations.  I’m trying to extract the Strehl Ratio from the Huygens PSF like in the image below However, I can’t seem to find how I can do this.  Can anyone help?

Hi, I would like to open the non-sequential 3d layout in MATLAB. Basically, I would like to customize the 3d viewer so to visualize rays belonging to different paths in different colors. Is there a way to open it via a MATLAB figure? Best, Mariangela    

Hi everyone, I have written a code snippet to display a glass map of the materials that are found in the current lens file. I don’t think this is possible to obtain from the Libraries..Materials Analyses..Glass Map, but correct me if I’m wrong.The full code is available on my GitHub.These are the imports that are necessary in addition to what is already in the interactive extension or standalone template:import matplotlib.pyplot as pltfrom matplotlib.ticker import FormatStrFormatterimport numpy as npimport chardetThis is the actual code snippet:# Glass catalog foldercat_folder = TheApplication.GlassDir# Number of surfacesn_sur = TheSystem.LDE.NumberOfSurfaces# List of materialsmats = []# List of indices of refractionrefr = []# List of Abbe numbersabbe = []# List of relative costscost = []# Relative cost scale factorscal = 100# Material found flagmat_found = False# Loop over the surfacesfor ii in range(n_sur): # Current surface data sur = TheSystem.LDE.GetSurfaceAt(ii) # Surfac

HI,Does anyone know if the following : singleTrace = ZOS.Z_Analyses.New_Analysis(ZOSAPI.Analysis.AnalysisIDM.RayTrace);singleTrace.GetResults().IsValidcan be used as the error code for the single ray tracing? just like the error code returned in the batch ray tracing?Thanks!!

I’m converting ZPL macros to ZOS API using C#I have a macro that calls GETSYSTEMDATA 1The contents of the operation at placed in a “vector” . Per the documentation, the vector’s "index” at 18 is  “Total Track”I’ve having a hard time finding the corresponding API for accessing “Total Track” data.Does anyone know the corresponding   ZOS API code?

Hi I am trying to track the x, y coordinates using API. I know in Macros I would just use the following: SYSP 102, 1, xSYSP 103, 1, yanyone know how to pull these coordinates using API (Matlab) ? Thanks!!

I’m converting ZPL macros to ZOS API using C#I’ve having a hard time finding the corresponding API for the macro SPRO(surf, code) with Code = 18From the macro documentation, code 18 will return the Glass Number (an integer?) for a Surface.Does anyone know the corresponding   ZOS API code? I currently use OpticalSystem.LDE.GetGlass() to get the glass name. How about accessing the glass number?

I have a custom FilePath that I pass into the above method and I am trying to check to see if it is valid so I can alert the user if OpticStudio was found on the local machine or not.  However, when I pass anything to the method the bool is true and only the HandleError() method in BeginStandAloneApplication() catches the incorrect FilePath input.  Can someone point out my error or offer any advise as to what is going on?  Thanks in advance.The method StartZos is the only method I have changed so far.TypePath is hardcoded to always be as 0 or 1.The solution compiles and works as designed expect for the bool issue.There is an XAML GUI calling the Program class.namespace CSharpStandaloneApplication{ public class Program { public static void Main() { } public static string StartZos(int TypePath, string FilePath) { bool isInitialized = false; if (TypePath == 0) { //Find the installed version of opticstudio automatic

I am looking at the ZOS-API Help file, but I’m not able to find a way to get the row number of the DMFS operand.My final goal is to programmatically build a DMF at that location. Should I scan the MFE rows 1 by 1 in a for loop, until i find that operand type?

Good morning, I’m trying to connect Zemax with Python and I know that ZOS API and PyZDDE are possible options to use. Now I wonder if it is possible to use PyZDDE with the latest version of Zemax OpticStudio or if some functionalities are not supported with this connection. 

Hello everyone, What would be an elegant way of computing the path length (for every ray) from a direct unpolarized (sequential) batch ray trace in the ZOS API (since I don’t think it is returned by this tool, but correct me if I’m wrong)?I was thinking of going surface by surface, each time finding the intercepts in X and Y, and computing the path length based on the Thickness between the two corresponding surfaces, but this requires a ray trace for each surface, and before I go in this direction I wanted to hear from other people’s experience.Thanks for your help, and take care, David

I am totally new to OpticStudio, and I am trying to follow the PPG example to get started.

Hello everybody,I am Nuclear Physicist and I’m newer of OpticStudio. I’m following the official OpticStudio guide in order to build a Spectometer UV that can work in the range 250-300 nm.A little remark about the project: How i said the source is in the range 250-300 nm and the light passes through the first lens and cuvette and exits through the second lens.Bearing in mind that I have as sensor a 2.8 cm SiPM row with 50 um cells, in order to obtain a resolution of 1 nm, which focal length should I choose for these two lenses in order to obtain an Airy disk on the sensor < 50 um?After this second lens, the light is focused towards a hole so as to inhibit the passage of unwanted light, after the spot the light is collected by another lens and the parallel beam hits a grating.Same question: in order to obtain a resolution of 1 nm, which focal length should I choose for this lense in order to obtain an Airy Disk in the sensor < 50 um? Of course I also want lower aberration.After whi

We can use ZOS API Python to create and run the ZPL Macro Solve. Let’s have an example of ZPL Macro Solve. Applying ZPL Macro Solve in Multi Configuration Editor.  Now we create this Test_config.ZPL from Python program and run in for loop for all 3 configuration.We can use ZPL Command as string in Python Program and write in the text file. Then save the file as ZPL in ZPL Macro folder. If we use forloop then we can create and run multiple ZPL Macro solve. As in Multi-configuration, for each configuration need seperate ZPL Macro Solve file.  Python Code :NumberOfConfigurations = list(range(TheMCE.NumberOfConfigurations))# print(NumberOfConfigurations)ZPLFolder=r"C:\Users\s.rajan\OneDrive - Zemax LLC\Documents\Zemax\Macros"data=[]files=[]fg=[]for i in range(len(NumberOfConfigurations)):    filename="Test_config"+format(i+1)+".ZPL"     fg.append("Test_config"+format(i+1))    file= open(os.path.join(ZPLFolder, filename), 'w')  # Create ZPL file    data.append(str("x_APMN=MCOP(1,")+ format(

In the OpenBatchRayTrace tool, for AddRay it appears Hx, Hy, Px, Py can be arrays.  But when I pass the same arrays to GetDirectFieldCoordinates, it gives an error: No method 'GetDirectFieldCoordinates' with matching signature found for class 'ZemaxUI.ZOSAPI.Tools.BatchRayTraceTool'.  It runs fine if I pass single values to Hx, Hy, Px, Py. Can GetDirectFieldCoordinates take arrays, and if so what’s the format? Thanks
