Dear Zemax Team, is there a way to get a bigger font size for the axis labels? I cannot find any setting in the graphics settings or the project preferences nor any reference to this on the web. Best regards and thank you very much. Markus

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

Hi,i am trying to create a cylindrical mirror with elliptic shape, but i cannot find the proper surface type in NSC. My aim is to steer light from one focal point of the ellipse to the other and use two halves of this shape for two light sources, while tilting both half elliptic shapes to match their second focal point. See below.What type of surface could i use?

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!  

I have a fiber output which is collimated by a simple PCX lens.  I check the beam collimation with a shear plate.I’d like to model this using POP but I’m not sure it’s possible?  Seems like I would need non-sequential mode to account for the splitting. Or is it possible another way, maybe using the Huygens integral in NSQ?

Hello,I have a question to this article:How to use multiple ABg profiles to define an object's surface scatter property – Knowledgebase (zemax.com) I have just implemented my scattering ABg-File model in Zemax OpticStudio with 3 profiles based on measurements.This scattering model fits well for AOI=10°, however, for AOI=50° and AOI=80° it does not fit to my measurement data. Thus I would like to use separate ABg sums for these 3 Angles.Is this possible in Zemax?Do I need to program a DLL? At least for single ABg models per Angle I can use the Scatter Catalog, but not for ABg Sums, right?Fitting ABg scattering coefficients from raw measured data – Knowledgebase (zemax.com)Best Regards,Johannes Störkle

Dear Community, I have a problem when I want to export my lens data to a STEP file. It is somehow distorted when I open it with Solid Edge. I tried also Autodesk Inventor, but it looks the same. Please find attached my mirror design (Elliptical Mirror CAD) as well as how it looks like with Solid Edge. I already checked that ACIS Libraries are not set.What confuses me is when I reduce the aperture (which is elliptical) in x-direction from 120 to 80 it works. Please also find those files attached (Elliptical Mirror CAD 2 and Elliptical Mirror Solid Edge 2).Do you have an idea how I could fix this problem?Thank you very much in advance.Best regards,Andy

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 simulated the Huygens PSF with the same spherical biconvex lens in both sequential and non-sequential modes, however, I found that they are not the same. I checked the wavelength of the system, the distance between the planes, but still can't find what the problem is, and I'd love someone to help me! The corresponding simulation file I have added in the attachment. I would be very grateful if I could get your help. 

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

The puzzles come from when I try to use POP to simulate the diffraction effect of my Grid phase which is written in Matlab.I set a system with object at infinity, surface one is a dummy surface. Surface two is my Grid phase with distance 0 behind the surface one.First I check the Grid phase in the phase map. Intepolation is pixelated. The phase ranges from -0.49~0.49 (unit 2pi) and center point has phase 0. Operade RAED at surface two for the chief ray of on axis is 7e-4. Total pixel is an odd number to ensure no offset.The propagation in POP starts from surface one and ends at surface two. The pixel size is set the same as in the phase map. The phase after surface two ranges from -3.09~3.14 (radians), which is non-symmetric and different from what I see in phase map. The center phase is non-zero, phase refers to a plane. Since the propagation distance is 0, I don’t understand why.An additional general question is (not related to the above), if the chief ray is slightly tilted and sele
