Hello Everyone,I’m trying to get a spot diagram and psf of a system with tilted window. The system is a simple 1:1 imaging with two f=50mm paraxial lenses.However, when the window is tilted in 45 degrees (I did the tilting using the “Tilt/Decenter Elements” tool in LDE), the spot diagram and psf looks weird. Below shows an elliptical beam when slightly away from focus. I wonder what’s the reason that causes the beam deformation?  Thanks,Sean

Dear Community,I was trying to make the drawing for fabrication of  a binary surface. To get the sag and zone radius of the binary surface I am using "DoeSag.zpl" macro as given in this ZEMAX article.I have also made an excel sheet to convert ZEMAX phase coefficient to the coefficient that will be provided to manufacturer. But the value specified in ZEMAX after running DoeSag.zpl is not same as what I am getting from excel sheet. I have checked my excel formulas several times and it is working fine for another DOE (excel and ZEMAX values are matching).  What could be the reason for this?Thanks. 

My laptop system just crashed yesterday out of sudden and I was unable to reboot it at all. I did not have a chance to do the Zemax license transfer due to such unexpected event.  Is there a way for me to get the license transfer code at all? Thanks!  

Hi,I am trying to change 3D layout properties via MATLAB ZOSAPI. I’ve checked help and googled and didn’t find the answer.  For example, how could I change “Number Of Rays”, “Ray Pattern”, Rotation and all other settings via ZOSAPI. Also, is it possible to change line thickness via ZOSAPI??     

Hello,          I am getting an error when I try to import a creo file.  Not sure if it is the file or OpticStudio.

Hi everyone, My question doesn’t relate to OpticStudio, but I’m hoping to find someone who can help me here so I hope you don’t mind.I have a 2-axis galvanometer scanner, and one of the mirrors seems badly oxidized. The reflection of the defective mirror is just above 0.6 (while the other one is around .94). We can still use this scanner but we are a bit on the edge with our light source power. The company who sold the scanner has discontinued this product and doesn’t want to repair a single unit. Ideally, we don’t want to buy another scanner. Do you know someone who would be willing to repair our mirror? It had a broadband visible coating.Thanks for your help and take care, David

Hello all,I am new to the Zemax/OpticStudio community and still learning how to use the program.I was wondering, is there a way to open windows other than ‘Lens Data’ when creating a new file or on startup?Thank you for your helpBest,Richard Liao

I have a need to simulate coherent irradiance (power) on the detector in non-sequential mode. First I have tried to proceed the data directly from ZRD file. Based on equations on page 790-791 in Zemax manual I summed all Re and Im values of every ray hiting particulate pixel (based on x,y coordinate on the detector) in all three directions (X,Y,Z) and then calculate RMS value (TOTAL = sqrt((Re,x^2 + Im,x^2)^2+(Re,y^2 + Im,y^2)^2+(Re,z^2 + Im,z^2)^2). When I use the DDR output from detector ( no smoothing, incoherent output) I get similar result but only similar (see figures). The amplitude for both outputs could be relative however, the result from DDR is smoother that ZRD. Since I am new to Zemax I do not want to continue with more complex simulations unless I fully interpret those results. My question is shall both outputs (DDR and ZRD) yield the same results? If so what may be wrong with my approach?Thank you very much for any clue.

I’m trying to model an anamorphic lens in non-sequential mode. The lens is planar on the incident side, and aspherical on the output side, with different asphere equations for x and y coordinates. The ‘Aspheric Surface 2’ seems to offer what I need in terms of the ability to specify different conic coefficients for x and y, but I cannot figure out how to create a volume from this. The format used in sequential mode, where the surface is preceded by a standard surface where the material is specified doesn’t work.Presumably the solution will be the same for any of the surface geometries offered in NSC mode, but all the examples and knowledgebase articles I can find apply mirror coatings to these surfaces, so they are modelled as infinitely thin shells.Any help would be greatly appreciated.

The acceptance NA for a fiber is found by the expression NA = Sqrt(n1^2-n2^2), and the arcsin of this is the acceptance angle. Yet, I am finding a small number of rays are clearly entering the fiber. I am using a multi-mode fiber model in non-sequential explicitly constructed with concentric glass tubes. What is happening here?

I created a self-defined polygon object, roof prism, and set it as a detector. How should I distinguish which pixel point to which triangle surface? 

Hi,I have ticked S+A Irregularity and set a value in tolerance wizard, but the relevant TIRR operand is not automatically generated in the tolerance data editor. Is this a bug or am I doing something wrong. Anyone can help? I am using OpticStudio 22.3

Hi all,I'm trying to reproduce an ellipsoidal off-axis mirror surface in Non-Sequential mode (which is part of a bigger optical system, hence the locations and orientations of sources and surfaces). I have reconstructed the parent ellipsoid as a biconic surface with its vertex in the following positions:Now I want to reproduce the curvature of this parent surface at position of incidence of the source (similar to what an aperture would do in sequential mode). My understanding is that the Off-axis mirror should be the element to be used here. The incidence point is:So there is an offset in positions X,Y and Z of the vertex of the parent biconic and the off-axis mirror. I constanly obtain Error 31 when trying to input the proper offset of the ellipsoid (which in the case of the system is around 1063mm). Beyond a certain offset (~600mm) Error 31 appears.Any ideas on why does this error appear? I could probably use some boolean element to reconstruct the mirror, however my understanding is

Hello,i need this: Automate client computer configuration for softkey and Red USB key network installations (Zemax legacy) – Knowledgebasefor the new Ansys Zemax OpticStudio 2023 R1.02. It isn’t saved in “C:\Program Files (x86)\Common Files\Aladdin Shared\HASP\hasplm.ini” anymore in the new version. Thanks

Hello,I’m trying to simulate the movement of a laser beam by tilting an element (e.g. a mirror). I’d like to see the movement of the beam on the target with a physical simulation where diffraction is considered (like the image shown below). I tried to use FFT PSF, POP and Extended Diffraction Image Analysis. However, none of these show the beam movement while tilting the mirror.I wonder what would be a proper tool, or how I can set up these tools to achieve this task?  Thanks,Sean

If I have a complex multi lens system, and I am trying to verify a few parameters,  of a single element, is it possible to “evaluate” or ping certain Zemax parameters directly ?  For example if i wish to to confirm the EFL of element #3,  spanning surfaces 6-7.   Is there anything like a single command :   EVA  EFLY  or EFLA  S6-7   ??  [Mod note: moved to more appropriate forum for OS-related discussions.]  

I am trying to exprot some useful data from an optcial lens. I used CFG files and MODIFYSETTINGS to extract them.But, I could not find any keywords related the distoriton. The CFG of the distoriton was found, and it was “FCD.CFG”I tried some commands such as MODIFYSETTINGS CFG_FILE$ FCD_WAVE 1, but errors occurred.I want some keyword for the FCD.CFG I have another question about report data.In analysis tab, there is a prescrpition report data.There are lots of information of the lens which are very useful.I want to save the report in ZPL.I opend the report using OPENANALYSISWINDOW "pre".However, i can not find any option for saving the report.I tried it using SAVEWINDOW command, but it did not work. If you have any soloution for them, please let me know. Thank you.

Hello,I’m attempting to create a lenslet with a biconic front surface to match a grating mode. We need the CAD for this surface for some other software we are using, but I am unable to export the surface without OpticStudio crashing. The surface has admittedly steep curvature, but I don’t think it’s anything normal CAD software wouldn’t be able to produce, so I’m confused why I’m unable to export this surface? For reference, it seems that OpticStudio has issues with surface 2, rays are not included in the export, and usually it just crashes (closes to desktop) without producing any type of error window. Lenslet profile (Y,Z)Lenslet profile (X,Z)Lens Data  Let me know what other information you might need.Thank you

--Need Help--I have this issue, I have two CAD objects in Hybrid mode. I would want the light beam to reflect after it touches on the CAD surface. However, the light beam seems to ignore the coated surface and passes through. Any reason why this is happening? 

Hi,Here is my very simple setup and its spot diagram, which is smaller that Airy Radius, so I wanted to investigate PSF further using FFT PSFbut I don’t get any image, just black windowAfter that, Zemax is slowing down, stopped work and closed. When open Zemax again,  I am getting this messageI have tried with other file ( but with similar simulations) it is happening again - I am getting black screen for FFT PSF and Zemax is down. I am sure my laptop has enough RAMs to accommodate Zemax. Regards,Marzanna

Can ZEMAX model different wavelength with different sources without using multiple configuration? The reason is that I would want to see all the light collimated to a single point which is to lens 2  

I am trying to update and use a set of Python scripts. The code used to retrieve surface comments from the Zemax model no longer seems to work in OpticStudio 23.1. This code was all written several years ago, so uses the older win32com library rather than the newer preferred .NET approach, but it does still work on another computer running OpticStudio 22.1, so has something changed in the API definitions over the past year?surface_name = system.LDE.GetSurfaceAt(k).Commentdoesn’t return a string, but <COMObject Comment>, and I can’t work out how to actually get the string out of this.The script works if I replace this line with surface_name = str(system.LDE.GetSurfaceAt(k).GetSurfaceCell(1))While this fixes the problem, it’s obviously less readable, and I’m not sure why this change is needed. Any suggestions on why the original code isn’t working any more? 

OpticStudio only supports CAD models created in Version 4 of Creo.  Creo V4 is 5 years old and the latest version of Creo is now Version 8.  Isn’t it about time that the development team updated Zemax to work with newer versions? Andrew

Hello, I’d like to know how to output a set of Zernike values when running Tolerancing when I have two separate configurations?Setup: There are two wavefronts being evaluated in each configuration. Tolerancing is setup to run a User Tolerance Script. The TSC loads a merit function with criterion for both configurations. There is a setting under Tolerancing→ Criterion that allows for the configuration to be set to “All”, “1/2” and “2/2”. The TSC computes the standard Zernike terms within and reports them to an output TXT file.Issue: Running in any CFG mode produces the nominal system output and only one evaluation of the MIN/MAX tolerance. If running in “All” mode, the Zernike values for CFG 1 are reported, same as running in “1/2” mode. Running in “2/2” modes, the Zernike values expected for CFG 2 are reported. Question: Is there a trigger for the TSC or a setting such that Zernike values for both configs are output during a single tolerancing run? Given the TSC is called at each itera
