Beam Displacement in Physical Optics Propagation

Hello, I am trying to simulate a system that uses a Acousto-optic deflector to introduce an angle so that we can scan the beam around a few mm range.  I am using a diffraction grating to simulate this in Optics studio but when I use POP to analyze the beam, it seems to always display in reference to the beam center, regardless of the actual displacement caused by the beam angle.  Is there some way to have POP show the actual location of the beam? Maybe it is something simple I am missing. I attached a picture in case my question was not clear. the orange highlighted surface is the surface that I am looking for the displacement at.  Thanks for your help and sorry if this is a silly question!

How to save a 2D array variable outside ZEMAX macro

Good morning, everyone. I am currently modelling a prism compressor with ZEMAX and I would like to, by coupling with Matlab to extract the pulse front tilt from the compressor. As I haven't yet entered the ZOS-API, which would probably be the most direct solution to my problem but for the moment too complicated for me ;-), I would like to manage it simply from macros. Is there a way to save a 2D variable generated under a ZEMAX macro to import it under matlab? Thank you for your valuable insight! Translated with www.DeepL.com/Translator

Changing the number of cores in a ZPL macro?

You can change the number of cores being used in OpticStudio User Interface. For example when launching raytracing in non-sequential mode. Here is how to do the same thing from within a ZPL macro: !through the system properties, code 901: SYSP 901, 1 !measure time TIMER !raytrace NSTR 1, 0, 0, 0, 0, 1, 0 PRINT "Elapsed time:", ETIM(), "Seconds" !number of cores print SYPR(901) SYSP 901, 16 TIMER !raytrace NSTR 1, 0, 0, 0, 0, 1, 0 PRINT "Elapsed time:", ETIM(), "Seconds" print SYPR(901) Here is the text output:

ASCII Ray file

Hi, I'm using the binary file converter on your website to convert a .DAT ray file into an ASCII text file: https://customers.zemax.com/os/resources/learn/knowledgebase/how-to-convert-a-binary-source-file-into-ascii I should then be able to use this ASCII ray file in my design (I know that raytracing will be much slower). However, I don't know how to import such file in Zemax. It is located in the Source Files folder (same as .DAT ray file) on my computer but it doesn't appear in the list of Data files when I'm using a Source File Object. What I'm I doing wrong here? Thanks, Sebastien

'Pass_P' coating fail for the modeling of a wire grid polarizer, how to model it correctly?

I'm using coating 'Pass_P' to model a wire grid polarizer, which is made by fabricated narrow metal stripes on a glass substrate. The polarizer should reflect s-polarized light, while transmit p-polarized light. But the coating cannot handle it correctly, when I setup my system,  why the normal incident S-polarized light pass the surface with 'Pass_P‘ coating.

FEA, SigFit & ZEMAX: coordinate system orientation

Hi, The standard method for defining the direction of the Z-axis is that positive is towards the image plane. This is opposite to what my team's FEA & CAD team has been doing and prefers. We are looking at integrating SigFit for thermo-optical analysis. For implementation of SigFit the coordinate systems need to align.   Does anyone have any experience in changing the Z-axis orientation? The CAD & FEA team prefers that we first investigate just changing the definition of positive Z in ZEMAX. Or will it be a better procedure for the FEA & CAD to default to the ZEMAX optical system Z-orientation (positive towards the image plane)? Regards, Dalene

How to obtain data shown in a plot?

I have a phase vs angle plot (Analysis->Coatings->Phase vs angle) whose values I would like to import into another program (e.g.Excel) for further analysis.  Is there a table of the plotted values available somewhere?  if not, is there a way to get them using a macro?

Why do I get an elliptical polarization after a 45-degree reflection in a mirror?

Hello, I have set up a 45-degree mirror in sequential mode, and I run into a result that I want to make sure is a physical phenomenon and not a bug in the program. In Sequential mode, I set up collimated light hitting a the MIRROR surface in a 45-degree angle.  When I open the Polarization Pupil Map analysis window and set the input polarization axis to 45 degrees, I expect to see 45 degree polarization. However, as you can see, the Polarization Pupil Map shows slightly elliptical polarization. I would have thought that metal mirrors caused a phase shift of pi both for S- and P-polarized light. I wonder if what I see in the OpticStudio results corresponds to a real physics phenomena or a bug in the program.

Which programming language and which version of OpticStudio can use ZOS-API?

That discussion gives a quick overview of the most used .NET or .COM capable languages to communicate with ZOS-API. Which version of OpticStudio supports ZOS-API? ZOS-API is available since OpticStudio 15. More and more functionalities are being added to ZOS-API. Which tool, program can connect to ZOS-API? The ZOS-API can be used with any .NET-capable language or any .COM-capable language. For more information about the connection, consult the built-in Help File under The Programming Tab…About the ZOS-API…Get Connected… Here is a non-exhaustive list of the programs that can interact with ZOS-API: Language .NET .COM Comments C# X C++ X Matlab X From our experience, any Matlab versions above 2015 can access .NET libraries.  For more information, see https://uk.mathworks.com/help/matl

How does OpticStudio calculate MTF and spot size with a paraxial lens in de-focus?

Hi, Question as described in the title. The spot size i mean here is neither RMS or GEO spot size, it is the calculation size like Airy Radius with diffraction effect consideration. Airy spot size is the min spot size in focusing distance, but how does OpticStudio calcuate the spot size in de-focus distance? what is (are) the formula(s)? Similarly for MTF calculation, just using a paraxial lens with known EFL and imaging F/#. Thanks, Roger

Could we have categories like in the old forum ?

Currently, the topics are all mixed in one big pile of which only the last few are visible. This is much less useful than with the previous implementation. Please reintroduce categories, along the lines of Sequential / Non-Sequential / POP or better yet, reuse that of the old forum and import the old messages so all that useful information is not lost.

ISO Drawing Problem

Hello After having opened a lens file I sometimes want to check one or the other ISO drawing, which had been created with this file in the past. I proceed as follows: in the GENERAL Tab I click LOAD, select the ISO drawing of interest and after it has opened I click APPLY. Most of the tolerances appear correct but the shape of the lens not. OK, then I go to the GENERAL tab again and select the correct start surface for that lens. Now the shape looks better BUT - the 2nd radius of curvature flipped from plus to minus. So I now have a plano-concave instead of a plano-convex lens... Of course, this can be corrected by applying "Reset from LDE" but now my manually defined AR coating for that surface, which was not input in LDE, disappears...Manually defined coating was also the reason for unclicking "Automatic" in the associated surface tab. Anybody with similar experience? Best regards, Dusan

The Universal Plot does not consider TCE values in the Lens Data Editor

I've setup a Universal Plot to display the variation of ensquared energy (DENC Merit Function operand) with the temperature (TEMP Multi-Configuration operand). At first glance, the plot looked convincing. However, when I changed the TCE of one surface, the plot did not changed even slightly. Therefore, I think that the TCE is not accounted in the Universal Plot. Could you confirm?

How to reset/adjust the window layout

OpticStudio uses a layout manager to determines how to position and resize the windows. This manager can sometimes go into a state where the window of an editor/analysis take a default undesirable shape. This thread idea has been suggested and co-written by Dusan Zadravec.

Can OpticStudio be used to model any portion of the electromagnetic spectrum?

Although OpticStudio is well known for modeling visible, infrared, and ultraviolet applications, but is it accurate when using radio, x-ray, or other "non-optical" wavelengths?

Should I use Planar or Spherical Reference when using Huygens for single-mode fiber coupling

This is a frequently asked question. To answer this question, let's slightly discuss how spherical reference works. When calculating Huygens PSF with Spherical Reference, OpticStudio will first trace rays to image surface and then "go back" to exit pupil like below. Then each ray interception point on the exit pupil will be considered as point source that radiate spherical waves and interfere on the image plane. This is called spherical reference. On the other hand, when in planar reference, each ray is simply considered as a plane wave and still interfere on the image plane, which is same as spherical reference. The difference of the two methods will mainly be large when the Huygens PSF is supposed be large. OpticStudio will detect this by checking the distance from exit pupil to image surface and the expected size of the PSF. Back to the discussion about which reference we should use. Usually, we can let OpticStudio decides automati
