Hi All, I have multiple configurations set in zemax opticStudio.How can I export the CAD file together with the geometric ray tracing of these multiple configurations into CAD softwares?Now zemax opticStudio can export the CAD file of  single configuration.I need to export the Layout together with the ray tracing of multiple configurations to CAD software, how to do it?  Thank you,

Hello All,I would like to import measurement data from a double pass Shack Hartmann wavefront sensor.I have the INT file ganarated from the measurement software (the first few lines of the files is attached).What i want to do is compare the ideal lens wavefront model (from Zemax) to the real measured Wavefront from the measured data.Is there a way to import and compare the wavefronts? Thank you for the help,Amit

Hi everyone,I’m trying to design an optical system with 2 different configurations. One of those configurations would be with an afocal image space (Wavefront criterion in optimization wizard), and the other configuration should be optimized to get a minimum RMS Spot Size (Spot criterion in optimization wizard). Is there possible to add both groups of operands directly to the same merit function without having to copy and paste the operands? As I see it, the ‘Apply’ button could simply add the resulting operands given by the selected criterion to the already existing merit function in the editor, but it also removes the existing operands.Thank you in advance for your help!

Hello, All I’m looking for how I can convert the values from Zernike Standard Sag to Zernike Standard Phase for TOLR Analysis The Lens Data applying Zernike Standard Phase to Extended Polynomial surfaces in TOLR Analysiswhen we are closed look for Lens Data, I set Extended polynomial and Standard with Zernike Standard Phase.It is expedient to apply surface Irregularities which is for can not apply directly to Exteneded polynomial.Of course I know that there is new function names Composite Surfaces, however The TEZI operands of composit surfaces  can not apply now. (Special Case)So I set the surfaces to duplicate real phenomenas and to be avoid the situation that could not apply TEZI opperands to the surfaces(not Standard).So, what I would like to ask you is how I can determine the scale factors from Zernike Standard Surfaces(will be change by TEZI Operands) to Zernike Standard Phases. Picking up from Standard surface16 to 17 zernike 7NO reflecting TEZI result applied on surface 16 with

If you system has vignetting, is there a way to list surface(s) are doing the vignetting?Thank you,John 

Hi,Is there a way to add a surface or lens notation (names) in the 3D layout analysis?Automatically, not drawing manually.Something similar to CODE V.Thanks,Eyal

Hi all: I am using the Universal 1D Plot to generate Decenter-X vs FICL on a Coordinate Break surface.I checked the 2025 R2.01 documentation but couldn’t find any links on how to identify which Parameter# should I be using for Decenter X, Decenter Y, Tilt X, Tilt Y and Tilt Z. cheers - asuku

Dear Zemax Support Team,I have a question regarding the Huygens PSF calculation in afocal optical systems. Since afocal systems do not form a real image plane, I would like to understand how Zemax handles this scenario. Specifically:Does the Huygens PSF in an afocal system represent the far-field angular distribution (similar to an angular PSF)? How does Zemax define the reference plane for integration when there is no real image plane? Is it based on the paraxial image plane, a user-defined surface, or another method?Any clarification or documentation on this would be greatly appreciated.Thank you for your support!\

Hello!I am able to read in the tabular numerical values from a ZTD file.But how can I read in the column names, row names and extra data as you see in a ZTD file? Thanks

Hello, I want to perform tolerancing analyses for all wavelengths of my system simultaneously, not just the ‘test wavelength’. I understand that I could simply write the wavelength operand TWAV for each wavelength, followed by the list of other operands copied each time, however there are two problems with that: 1. It doesn’t take into account the weighing of different wavelengths. 2. I suppose it artificially increases the deviation of the criterion, namely, it sums the deviations (in the RSS meaning) of different wavelengths rather than averaging them. Is there any way to tackle this? Thank you. 

Here is an example of a simple 2f system to compute fiber coupling (located in Zemax samples).The MFE operand used here is FICL to calculate the Fiber Coupling efficiency [η]. When using Zemax Tolerance, I set the Criterion: Merit Function → Run Monte Carlo.As you can see, the compensated parameter values are totally out of whack from the bounds I set.Zemax documentation clearly states that “This bounding of the compensators is ignored if "merit function" or "user script" is selected as the tolerance criterion,  although the compensators will still be used.”If that is the case, then what is the right way to bound the compensator(s) when using a Merit Function Criterion? Nominal System Perturbed Monte Carlo system with compensation: The compensation is totally out of whack. 

Maybe it’s just me, but I am no more able of opening the “Go To Surface” popup window from any Editor.The following does not come up (image taken from Help file):I am using opticStudio version 2025 R1.00

How to update opticstudio to the latest version

Hi, I am modelling a setup in which an LED light source is homogenized using two fly's eye multi-lens arrays.There exists already a tutorial on a fly's eye setup:https://optics.ansys.com/hc/en-us/articles/42661744169363-Fly-s-eye-arrays-for-uniform-illumination-in-digital-projector-optics In my setup, I have chosen components that are all off-the-shelf available.My setup consists of:1. LED light source, wavelength = 340 nm, emitter size = 6x6 mm.2. Collimating lens, spherical type, focal length = ~50 mm @340 nm.3. MLA1: a multi-lens array with pitch = 7 mm (in X) and 5.4 mm (in Y) and nr of lenslets in X = 7 and in y = 9 and focal length ~ 40 mm at 340 nm.4. MLA2: identical to MLA1. MLA2 is placed in the focal length of the MLA, that is at 40 mm behind MLA1. This is the classical fly's eye setup configuration.5. A focusing lens with f = 474 mm @340 nm.  What I observe:1. A square-like top-hat profile at the focal plane of the focusing lens (see figure in additional post below).2. A cro

As per title, I face this issue every time, with many analysis windows, both with old and new graphics.Changing the windows aspect ratio changes the results.Good Bad  Bad                     

Hi zemaxers I am trying to understand how coordinate breaks work in Zemax, and I have a question about the tilt pivot point for a mirror. When a mirror(component) is used, the tilt pivot is typically at the back surface of the mirror(?). I’m wondering how to set this up in Zemax when using a mirror surface that has a defined thickness. PS: I read this, and tried as file attached.   Thanks for your help YANG

Hi,  I am trying to run non-sequential sequence in a loop, for which I change a parameter and save the detector data for each loop. The text tab should allow me to export the irradiance data at each coordinate, but I am a little uncertain how I can grab detector 1 and 2, then save the data as text files as for example data_d1_01 and data_d2_01, data_d1_02 and data_d2_02,..etc. Any suggestions appreciated. My experience with ZPL is limited. My attempt: update ALLFILENAME$ = "data_xtilt"+ $STR(xtilt) + "_tiltY_" + $STR(ytilt) + ".TXT"savewindow 1, H:\_work\ZEMAX\+FILENAME$savewindow 2, H:\_work\ZEMAX\+FILENAME$This got an error “ERROR in SAVEWINDOW: Window 1 does not support text”

I have no issues using the code line in Zemax Programming Interactive Mode# mark cell as V# Surface 18 - LDE row number for compensator# Cell 15 - Decenter X/Y or Tilt X/Y/ZTheSystem.LDE.GetSurfaceAt(18).GetCellAt(15).MakeSolveVariable() But it raises the following error when I program and try to use it in a Standalone application mode.Error1Any ideas on why this happens?

Zemax in Non-Sequential:  I have a system with a grid of emitters, see below, and a detectors (polar and rectangular) about 1000mm away. I started by collimating the light which worked to get nice disscrete point; however, the magnification is not correct. I could change my target angle but this seems like it will just fuzz out the image.  I’d like to set the EFFL of the lens so that with the object to lens I get the correct magnification. What is the best way to do this? 

How do I turn this off? We pay to use Zemax, not to be an advertiser for Ansys.

I would like to study the tolerance of my optical system. I want to evaluate the RMS Sport and the RMS wavefront error at the same time in the same tolerance simulation. However, we can choose only one of the two criteria during a tolerance run. Do you know if it's possible to evaluate both criteria at the same time, and if so, how?Thank you very much.
