ZOS-API- How can I change the settings (e.g. apodization..) of the System Explorer?

For example, If I want to:  Set apodization type as Gaussian, use the enumeration ZOSAPI.SystemData.ZemaxApodizationType.Gaussian. Set Apodization factor as 1 Untick Fast Semi-Diameters Tick Adjust Index Data To Environment The following code can be used:  TheSystemData.Aperture.ApodizationType = ZOSAPI.SystemData.ZemaxApodizationType.Gaussian; TheSystemData.Aperture.ApodizationFactor = 1; TheSystemData.Aperture.FastSemiDiameters = false; TheSystemData.Environment.AdjustIndexToEnvironment = true; If I want to: Set Coating File as COATING.DAT Set Scatter Profile as SCATTER_PROFILE.DAT Set ABg Data File as ABG_DATA.DAT Reload above data files Add Title and Notes The following code can be used:  TheSystem.SystemData.Files.CoatingFile = 'COATING.DAT'; TheSystem.SystemData.Files.ScatterProfile = 'SCATTER_PROFILE.DAT'; TheSystem.SystemData.Files. .ABgDataFile = 'ABG_DATA.DAT'; TheSystem.SystemData.Files.ReloadFiles(); TheSy

FAQ - How many instances of Opticstudio can be opened at once?

What is the number of instances of OpticStudio I can open ? OpticStudio will allow you to open as many instances as your license is capable of. This section clarifies the limits for each license type and version of the software. For all OpticStudio18.9 and lower releases, the answer is always 2 instances per machine as this was built into the software. When OpticStudio19.4 came out, we also released new subscription licenses. These license types have some new and exclusive OpticStudio features, including additional instances for Professional and Premium. For those customers who have perpetual licenses and 19.4, the limit remains 2 instances for all editions of OpticStudio. If you are interested in converting to a subscription license, contact the your Zemax account manager or the sales team:  https://my.zemax.com/en-US/contact-us/ See the chart below for a breakdown: Single user or network Single user or network Perpetu

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!

Object space and image space plots

I frequently need to determine the MTF of a lens in object space rather than image space.  I would find it a big help to be able to have a check box for "object space, image space". It is easier to present to customers in object space because they can relate to the dimensions.  Also I often need to check the resolution over a focus range (in object space).  It's a bit tedious repeatedly working out the magnification at each focus range to scale the MTF into object space.

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.

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

GGD input file

Hi, Our team tried hard today to input a GGD file (placed in Glasscat folder) which contains the 3D index map of one of our desired gradient index lenses in order to trace the rays by Zemax.  While the exisiting sample file "Sample.GGD" in Glasscat with Grid Gradient surface type works perfectly, none of our own generated files works.  When updating  with our own GGD file, we always get this error message: "Internal Error! nx, ny, nz Sizes are incorrect". Attached you will find one of our GGD files.  We do not have any clue how to move forward with this problem now and appreciate your great help. Best, Hooman Akhavan Voxtel Corporation, OR USA

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.
