Hello all,I am a student in internship and I need to use ZPL to automate my system. I have a system with LED, which I am optimizing. After this optimization I have to measure the power received on the detector for different Z positions (34 positions).I do not know how to make a list of my different Z positions, how to change the value of the Z position for my detector and how to retrieve the value of the power received on my detector.Thank you in advance,Léo 

Hi everyone, I’ve recently started using OpticStudio. Currently, I’m trying to incrementally change the clear semi-diameter of a surface within my system. I know this can easily be achieved with a FOR loop.However, for each iteration, I hope to save the resulting wavefront map. Unfortunately, using GETTEXTFILE within a loop does not appear to work as intended, as the FOR loop seems to run as normal, but does not create the required files. I’ve attached my code. If there’s any mistakes or changes that need to be made so that the solver iterates over the semi-diameter values and saves the wavefront map at each step, just let me know. ! Setting the desired format.FORMAT 1 INTFOR i, 0, 6, 1    ! Reducing the clear semi-diameter by 5 lens units per iteration.    CLR_SEMI_DIAM = 52 - i*5    ! Returning the new clear semi-diameter to the editor.    SOLVERETURN CLR_SEMI_DIAM    ! Setting the output filename.    FLNM$ = "F:\LGS_104_Wavefront_Map_" + $STR(i) + ".txt"    ! Writing the wavefront m

Is there a way to to use the GETTEXTFILE function with an NSC detector? I’m running into the same issue, and couldn’t figure it out from the help page of the function. I’m currently using SAVEWINDOW from a detector window opened to the text tab and getting the same message.[Mod note: moved the post to a new forum thread.]

I have constructed successful interfaces with the ZOS-API using MATLAB, but there’s a larger system model that I’m now integrating into Simulink and I’m running into import errors because Simulink doesn’t seem to like the data structure.  Has anyone tackled Simulink interfacing?

Hello,How can I obtain the intensity of single rays (either using ZPL or API) when the apodization is part of a user-defined surface?I used the “us_filt1.dll” example provided with the Zemax distribution and set G>0. The APOI(x,0) operand returns 1.0 for all positions of the pupil (0<x<1), despite the apodization applied in the dll. Thanks!

Hello, I’m trying to control POP analysis through Python, and when trying to change the settings of the POP analysis window, I appear to missing the necessary ZOSAPI methods. Looking at this article, I see the below command to my_analysis = TheSystem.Analyses.New_Analysis(ZOSAPI.Analysis.AnalysisIDM.ANALYSIS_ENUMERATOR_HERE); When I try to do this myself, it doesn’t appear as though I can see the Analysis class for ZOSAPI. The only thing I see is the ZOSAPI_Connection class. I see that in the help it should have the Analysis namespace, but I’m unable to call it in Python. Thanks,Cedar Update: It seems I’m able to call the Analysis class even though it doesn’t appear in the IDE with the above command. Once I do, it shows up normally. I just have to remember what all the different methods/classes are named. My next problem is that according to the ZOSAPI help, the PhysicalOpticsPropagation should have the StartSurface property that I need to be able to set before running analysis, but I

Hi,I wrote a user defined bulk scattering dll (Non-sequential mode) that reads data from a txt file.I create/edit the txt file with Python which I connect to ZEMAX via ZOS-API. What I need to do is as follows (all lines using ZOSAPI and python):(1) Ray trace and Read detector data with Volume Physics bulk scattering set to None and save to a txt file (to be read by dll in step 3).(2) Change some variables for various objects(3) change bulk scattering to user defined dll(4) Ray trace and Read detector data(5) repeat from step 1 I’m having two issues (a small one and a huge one):the smaller issue - In step (1), how do I change Volume Physics bulk scattering to None? I tried the following:Obj = TheNCE.GetObjectAt(1) volphysdata = Obj.VolumePhysicsData volphysdata.Model = ZOSAPI.Editors.NCE.VolumePhysicsModelType.None However, Python doesn't allow this (as None is a protected variable). So, I found a different method which works , by changing to AngleScattering type and then set meanpath t

Dear OpticStudio users, In the context of my research at the MRC - Laboratory of Molecular Biology, I am tolerencing a custom light-sheet microscope, which uses commercial immersion objective lenses. When tolerancing an optical system, which uses non-immersion objective lenses, I would often assume that this element can be replaced with a paraxial lens in a first approximation. However, when it comes to immersion objective lenses, this assumption breaks Abbe's sine condition [1]. Consequently, it is usually not possible to satisfy the specifications, namely focal length, back-aperture diameter, and numerical aperture, of an immersion objective lens with a single paraxial lens. A direct solution to this problem involves patent search, and cumbersome reverse engineering to try and get your hands on the actual design of the commercial immersion objective lens. However, this is time-consuming, and requires a different kind of expertise. To address this issue, Hwang and L

Hey,i want to retrieve data from POP with the API (in python). As far as i got i understand that the pop_analysis.GetResult() is delivering a matrix, like the one you get from the text tab in POP. So far so good. But I don’t know how to get the index for peak irradiance or any other certain value. So, can anybody help me to retrieve the peak irradiance value from that matrix? I’d really appreciate any help that would lead me to a solution. There seem to be some options like “IndexOf”, “FindIndex”, but I don’t know how to use them. My code for that section so far:pop_analysis = TheSystem.Analyses.New_Analysis(ZOSAPI.Analysis.AnalysisIDM.PhysicalOpticsPropagation)pop_analysis.ApplyAndWaitForCompletion()pop_results = pop_analysis.GetResults()matrixData = pop_results.GetDataGrid(0).ValuesThanks,Mo

Hello, I saw a coupling topics on this but don’t see a real solution.Using the MATLAB API I can load a file and create a universal 1 D plot and change config settings. When I open the zmx file after I can see that the settings were applied correctly and the plot looks good. But, I cannot figure out how the access the plot data from the MATLAB API.  I’m using: UnivPlot = TheSystem.Analyses.New_Analysis(ZOSAPI.Analysis.AnalysisIDM.UniversalPlot1D);UnivPlot_Settings = UnivPlot.GetSettings();fprintf('Universal Plot has analysis specific settings? %i\n', UnivPlot.HasAnalysisSpecificSettings)% Above is False; Universal Plot Settings must be changed via ModifySettings (changing a config (.cfg) file)cfg = System.String.Concat(TheApplication.ZemaxDataDir, '\Configs\UNI.CFG');UnivPlot_Settings.Save(); % Create new .cfg file, named "UNI.CFG" in \Configs\ folder% Change universal plot settingsUnivPlot_Settings.ModifySettings(cfg, 'UN1_CATEGORY', num2str(0));UnivPlot_Settings.ModifySettings(cfg, 'U

Good afternoon.I have a question about working with numeric variables when writing an ZPL macro. Is it possible to round the values assigned to variables with the required accuracy? I'm looking for functions similar to (FLOOR.MATH) and (CEILING.MATH) in Microsoft Excel. I understand that i can create a loop that allows me to sequentially compare the value of interest with i and i+1 value. I would like to create an ZPLM operand using rounding, so it seems to me that this way will slow down the optimization, especially with a high degree of rounding accuracy.As an example, we can discuss the case where the value 24.432 needs to be rounded up to 24.0 or 24.5. 

Hi everyone, Since I have Ubuntu as a primary OS, I installed OpticStudio in a Windows Guest Virtual Machine. Is there any possibility to connect ZOS-API to my runnig Python scripts on Ubuntu ? Thank you very much  Greetings, Alaeddine Yacoub

HiI am learning how to build the MFE with ZOS-API and for that I am creating a simple MFE. I know that Target and Weight are accessible through  Operand.WeightOperand.Target But calling the Value column using Operand.Value returns 0. Any idea what I am doing wrong? Thanks 

Hi! I just started using the ZPL and what I would like to do is to create a solve based on a very simple geometrical relation. But, for doing this, I need to get the Tilt Y of a rectangular object (I am in NS mode).The only think I found is the numeric function NPAR, which it seems to me it only acquires parameters.What would be the right way to do it?Thank you!!! 

Hi,I’ve been building over the years a series of python based-tools that use ZOSAPI framework in order to automatize repetitive jobs. However, the reccurent changes in the API causes regular failures in these scripts. Lately I’ve been trying to use a simple piece of code that gets the sag from the surfaces and find the following failure (where ZemaxLDE is an instance of the TheSystem.LDE, and xi, yj are points where I want my sag to be returned):    tmp = ZemaxLDE.GetSag(index, xi, yj)  File "C:\Python27\lib\site-packages\win32com\gen_py\EA433010-2BAC-43C4-857C-7AEAC4A8CCE0x0x1x0\ILensDataEditor.py", line 103, in GetSag    , X, Y, sag, alternateSag)  File "C:\Python27\lib\site-packages\win32com\client\__init__.py", line 467, in _ApplyTypes_    self._oleobj_.InvokeTypes(dispid, 0, wFlags, retType, argTypes, *args),pywintypes.com_error: (-2147352562, 'Nombre de param\xe8tres non valide.', None, None) Could you please tell me what could have changed (I’m still working with Zemax 21.x beca

This macro will generate a GGD file based on user-defined formula. Before running this macro, define the ranges in xyz directions that you want to generate index data. And also define the number of points in each directions. The more the points are defined, the more accurate the interpolation can be, but the slow the simulation is. The index formula is defined in the sub routine "cal_index.". By default, this macro generates an index distribution that is Gaussian in XY-plane and linear changed in Z direction.   Click here to download Date Version OpticStudio Version Comment 2018-03-05 1.0 - Creation

Hi everyone, Inspired by this discussion with @Devorse, I made a User Analysis which sorts the Merit Function operands by descending order of contribution. The source code and executable are attached to this post.In the Double Gauss 28 degree field sample file, with a default Merit Function: Sequential merit function: RMS spot x+y centroid X Wgt = 1.0000 Y Wgt = 1.0000 GQ 4 rings 6 arms The Merit Function Editor looks as below:  And the analysis returns:  InstallationTo install this user analysis, download the attached archive (MeritFunctionContribution.zip) and extract it on your computer. Copy the file MeritFunctionContribution.exe to your {Documents}\Zemax\ZOS-API\User Analysis folder.To run the user analysis, after the step above has been completed, simply press Programming..User Analyses..MeritFunctionContribution.If you need to recompile the source code, please follow the steps outlined in this knowledgebase article.Note 1: there’s little error traping in the code, I’m not sure h

Good afternoon! I am studying the ZPL macro language in order to simplify the analysis of data in the optimization process. In the macro being developed, I would like to implement the function of sorting optimization operands by their contribution. I know that such information is in the "" section, but I'm interested in the implementation in the ZPL language. There are no problems with the sort itself, I use the IF-THEN conditions in sequence, however, I cannot find a way to display the name of the operand by its ID code. Initially, I thought that the numerical function OPER(…,1) could give me the name of the operand in the string, however, as it turns out, this numeric function returns the ID code of the operand. Could you help me? Thanks 

Hi there, I am trying to write a source DLL file to use in OpticStudio, which is based on the built-in source “Source Two Angle”. It would be great if I could use this as a starting point. Is the (cpp) code available for this source? Or is there something similar I could start with? Thank you!

Hi!I am experiencing a bug when running local optimisations via the ZOS-API in python. I am using interactive extension. Example of the code is:LocalOpt = TheSystem.Tools.OpenLocalOptimization()LocalOpt.Algorithm = ZOSAPI.Tools.Optimization.OptimizationAlgorithm.DampedLeastSquaresLocalOpt.Cycles = ZOSAPI.Tools.Optimization.OptimizationCycles.Fixed_50_CyclesLocalOpt.NumberOfCores = 8LocalOpt.RunAndWaitForCompletion()LocalOpt.Close()Upon running this, it sometimes completes correctly, but sometimes the optics studio window crashes and closes. Then when i open it back up, it asks if i want to restore the file. I have also tried this on multiple machines with different installations of ZEMAX, and the same thing occurs: sometimes it completes the optimisation and sometimes it crashes. Has anyone else experienced this issue, or know a fix? Thanks very much in advance!!
