I am new to DLL programming for Zemax. I have an older file using the Fixed-Data 3 standard. This should support 201 parameters. Unfortuneatly in the LDE editor a maximum of 12 Parameter columns are generated even if i define more. Is there a cap of how many parameters can be displayes as input in the LDE? 

Can I judge that the ray coordinates of EXIT PUPIL from the Ray Tracing command in Zemax have all three information: Lens DistorStion, Ralative Illumination, and PSF?

Hello,Is there a way to choose which source I want to raytrace in ZOS-API?In ZPL I’m familiar with the NSTR property but didn’t see similar property in the INSCRayTrace Tool. Thanks,Oran

These two User-defined surfaces DLL creates an array of hexagonal arranged lenses and an array of staggered lenses. The code is based on us_array.c.us_array_hex.dll has 4 parameters: the number of lenses in X and Y direction and the width and height of each lens.us_array_staggered.dll has 3 parameters: the number of lenses in X and Y direction and the width of the lens.Language: CppLocation: \Documents\Zemax\DLL\Surfaces\ [MOD: added the folder location for the DLL]   Click here to download Date

Hey Everyone! I am currently trying to figure out a way to get the coordinates of the Chief Ray from a Monte Carlo Run so that I get a dataset of Chief Ray coordinates correlating to different lens displacements.  I am using the the Merit Function Criterion for the Monte Carlo Run in the Tolerancing tab. My Merit Funtion consists only of the Headers and one operand ( REAY or REAX).  The results only give out positive values for the Merit Function but I need it to also show me negative displacements.I am new to ZOS so any help is very appreciated! 

How can only OBJECT's Clear Semi-Diameter be enlarged? I mean, I want to increase the size of the object's Clear Semi-Diameter without changing the size of the remaining Lens Surface. Can I know how with below System Explorer Setting? 1. Aperture Type "Float by Stop Size"2. Ray Aiming is "Paraxial"3. Convert Semi-Diameters to Circular Properties in the Lens Data Editor4. Change the field type to 'Object height'.  

Hi I’m currently attempting to run some a series of Physical Optics Propagations in parallel, using pythonnet. They are pretty simple standalone codes which load in a lens file, carry out the propagation and output the coupling. I’ve been using multiprocessing/Pool and have an unusual issue when using too many cpus.The computer I’m using has 16 cpus, but if I were to try and run more than 7 in parallel using Pool, I get a LicenseException (License is not valid for ZOSAPI use), though only for the 8th cpu.I just wondered if you had any insight as to what could be causing this/different recommendations for running the API in parallel in Python. Thanks!

Hello everyone, EDIT: I was wrong, NPRO’s last parameter is actually the wave number as pointed out by @MichaelH below. Therefore, there’s no need to use a user-defined operandEDIT: new version available in my last reply below! I have made a user operand equivalent to INDX for non-sequential systems.In non-sequential systems, INDX doesn’t work, and one workaround is to use a ZPL operand with the numeric function NPRO using the code 200 (index of refraction of an object). For some time, I used the following code in a ZPLM (I hope the code is self-explanatory but let me know otherwise):object = PVHX()OPTRETURN 0, NPRO(1, object, 200, 0)However, if one has multiple wavelengths defined, it always seem to default to the first one (wave numbe

Hi,The other day python.Net version 3.0.0, supporting Python 3.10, was released. Hence, I’m curious to hear when we can expect ZOS-API to support this very much appreciated combo.Best regards,Hans

Hello Everyone,I am trying to change the Aperture file of a surface aperture using python. All I could do is to change the Aperture type to User Aperture but the Aperture file is not specifyed.This is the code I am usingfilename= ‘HP.uda’User_Aper =TheLDE.GetSurfaceAt(2).ApertureData.CreateApertureTypeSettings(ZOSAPI.Editors.LDE.SurfaceApertureTypes.UserAperture)User_Aper.ApertureFile = filenameSurface_3.ApertureData.ChangeApertureTypeSettings(User_Aper) Using Matlab, it is working perfectly using the same code and also, it works that I can change the Aperture file manually in zemax so this means the aperture uda file is at the correct location with

Description: This macro will calculate the approximate FWHM of a near-Normal distribution of data. This macro assumes symmetry about the maximum value and assumes a minimal amount of noise between 0 and the maximum. The macro will update the Detector Viewer settings to a cross-section view. Then, the data will be extracted and evaluated. When using the ZPL10 version of the macro, the approximate FWHM will be reported when Data = 0 for the X-direction, and Data = 1 for the Y-Direction. Use the Hx entry to specify the detector of interest.  Language:ZPLUpdates:10/22/2021 - Stability and calculation updates. The calculation is now more robust. The code for finding the CFG file has been updated. See the ReadMe for more information. Download:

Hello together,I’m trying to save Ray Database ZRD to a file in a loop for each angle in the following script:...for angle, -10, 10, 2                x = NSDD (1,0,0,0)                 SETNSCPOSITION 1,2,6,angle                PATHRAY$ = "Rayfile_" + $Str(angle) + ".ZRD"                NSTR 1,0,1,1,1,1,1,1,PATHRAY$,"h133",1                 UPDATE ALL                PAUSE THREADSNEXT This just a part of my script, and exactly this part, namely the saving of ray database is not working. How can I save it, so I could have a few Ray Database files for different angles and open it later with the Ray Database Viewer? What is wrong here?Thank you in advance!CheersMax. 

I put all the scripts and detailed documents in the zip file, “star_load_fea_cli.zip”. The script “main_cli.py” is a command line tool that I use to import the FEA data to the system via the STAR module. The feature is almost the same as the “Load FEA Data” tool in the STAR module. The difference is that this tool cannot help you check whether the FEA data is in the right place. However, it might be able to help you finish some routine work. If the script is not convenient enough to let you finish your work easier and you want to build your own tool, I think you can reference the functions “load_fea_deformation_with_transform” and “load_fea_temperature_with_transform”. I believe that they will give you some help.

Hello Everyone, I want to run a DOE with ZEMAX where the idea is to generate synthetic data by running image simulations while changing position of lenses (adding decenter and tilt to individual lens elements in a lens stack).I want have a bunch of tilt and decenter scenarios and would like to automate the process via API.Is there a sample code that I could use for this application? Is there a sample code to automate image simulations and save resulting images in general that I could modify to suit my needs?All suggestions are appreciated :) Best regards,Amit

Hello, I would like to use a macro to save images from Geometric Bitmap Image Analysis for different configuration.I wrote this macro in ZPL to save the images obtained for different configurations but it doesn’t work:! Read the # of configsNCONFIG = NCON()!Read pathsettingfiles$ = "...\Zemax\Configs\IMB.CFG"! Execute for each configFOR i, 1, NCONFIG, 1    ! Set config    SETCONFIG i    img_file$ = $STR(i) + ".png"    MODIFYSETTINGS settingfiles$, GBM_OUTPUT, img_file$    OPENANALYSISWINDOW "IBM"    PAUSE THREADS    NEXTPRINT "DONE!"The configuration changes and the Geometric Bitmap Image Analysis window opens up and displays the right image but nothing is saved. Moreover, the output file name keeps the initial name and it isn’t modifying for each configuration. Do you have any idea to save those images ? (the folder path doesn’t matter) I also wrote another ZP

Hi, I am using Matlab to run zemax simulation. could you tell me how to set up the intensity threshold when I am using the “RayTrace.SplitNSCRays = true”. Thanks a lot. 

Hi,I’m using the Path Analysis feature (run from Matlab) to analyze how the light is going through a system. Path Analysis is a great feature!What I’m noticing is that if I add up the number of rays in the path analysis rows, they equal to the number of rays in the ray trace / and in the layout. However, if I add up the powers in the rows, there is a total loss of about 1.8%. I currently do not have any coatings set on the various components (struggling to get that to work for some unknown reason or the other). Just mirror/reflector and absorbers.Is there an atmospheric loss built into Zemax due to the air the light passes through? I tried setting the air pressure to zero in the System Explorer/Environment to try and simulate a vacuum, and it didn’t change anything. And, if there are air losses, I’d like to control them or set them to zero and calculate the losses numerically. Thanks!

The detector viewer doesnt work, how me always the same results….Why?A guide about simulating an integrating sphere can help me so much...Thanks for the support.The code is as attachments.Best Regards.

Hi,I am using the ZOS-API interface with Python (pythonnet 2.5.2.) to set the coefficients for a Zernike Standard Sag surface, one at a time. It takes several seconds!! Is there any faster way, or a way to set all parameters at once?I’d like to run a Monte Carlo analysis with thousands of istances of zernike surfaces, so a faster way would be really beneficial.%timeit M1_surf.GetCellAt(30).DoubleValue = 6.46449601150208e-06386 ms ± 28.1 ms per loop (mean ± std. dev. of 7 runs, 1 loop each)%timeit M1_surf.SurfaceData.SetNthZernikeCoefficient(4, 6.46449601150208e-06)354 ms ± 27.5 ms per loop (mean ± std. dev. of 7 runs, 1 loop each) As a comparison, reading a value is three orders of magnitude faster:%timeit M1_surf.GetCellAt(30).DoubleValue513 µs ± 78.3 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each) The LDE is the only open window, so there are

So my problem is roughly that I want to do my own tolerance analysis and retrieve the RMS Spot Radius value as my criterion. But after changing certain values, as the Thickness and Tilt X, the programme does not seem to register this. The Value is not changing and i just get the same value over and over again. Can someone explain how to effectively change these parameters in Optic Studio, so I can retrieve the actual RMS Spot Radius Value?I’m just assigning these parameters to my own values (f.e. from -10 to 10 with step 0.2) in a loop. Here a snippet of it:surf36 = TheSystem.LDE.GetSurfaceAt(36)mir1_thickness = surf36.ThicknessCell.DoubleValuemir1_tiltX = surf36.GetCellAt(14).DoubleValuefor indexTilt, stepTilt in enumerate(np.arange(-10, 10, 5)): mir1_tiltX = round(stepTilt, 2) spotdata_analysis = TheSystem.Analyses.New_Analysis(ZOSAPI.Analysis.AnalysisIDM.StandardSpot) spot_settings =
