Hello, I’m having issues with system I built. It contains an object (a prism) which is contained in nonsequential part. The system reflects the rays, until the last reflective surface, at which point half of the rays are reflected, and another half are transmitted. I do not know why this issue persists. The prism was built in SolidWorks and imported as .step file. I get error messages saying “Error in target 1. Missed surface 5” and “Error 10561: NSC group surface 4, source 0. Geometry error object 1 detected.” with additional info about coordinates.I would normally press the “Ignore trace errors” button, but I need to get information on spot size, chromatic focal shift, etc. so I need to fix it in order to be able to obtain this information. I attached the prism.step file and .zmx and zda. files in .zip archive. If somebody knows what’s the issue I’d be happy to hear the fix. Thanks in advance. 

Hello Experts,I am trying to compare a Shack Hartmann wavefront measurement with my Zemax wavefront map.Image depicting the measurement setup from the website of the Shack Hartmann Sensor manufacturer (Optocraft)The Shack Hartmann setup I have is a double pass system where the objective is illuminated with a plane wave output from the sensor with a spherical mirror placed below the lens under test. The rays from the mirror are reflected back through the lens under test and then through the internal optical system of the measurement setup to the sensor. I am trying to model the double pass system so that i can replicate the setup as closely as possible. What I have done so far is:1. Use the “make double pass” replacing the image surface with a spherical mirror. This makes the first surface of the lens under test as the new “image” surface (after making double pass the first surface is also the last surface)2. I use the knowledge base article  “https://optics.ansys.com/hc/en-us/articles/

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

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

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

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,The following  ZPL-macro is run which performs a geometric analysis and then saves the text of this window: OPENANALYSISWINDOW IMA, GIA_cfg_file$n_GIA_window = WINL()SAVEWINDOW n_GIA_window, A$ The size of the image is 125 pixels, resulting in a text file size of 400 KBWhat I observed is that the time it takes to execute the SAVEWINDOW function takes a very long time of about 20 seconds (!), regardless of whether the text file is a temporary or permanent file.The saving takes nearly as long as the execution of the image analysis.However, if the text output of the very same “Geometric Image Analysis” window is saved manually to the very same file A$, the saving is performed in no time.The subsequent extracting of specific strings from this text file by using OPEN, READSKIP and READSTRING  is also  executed within “no” time. So my question is:why is SAVEWINDOW so slow or more importantly: how can I significantly speed up the saving process?Best regards, Marcel Zemax-Version:  Ansys
