Good day! Maybe someone knows, is it possible to create in Opticstudio some “model” of optical elements group with known aberrations (of whole group)? I need to assess obtained image of certain object before accessing official blackbox model. Thank you for help!
Hi dear Staff, I am able to define the distances between the objects in Non sequential mode.But when the object is rotated say for example a beam splitter is tilted, how can I define other objects by considering beam splitter as a reference ? In the below layout, Beam splitter is the reference for lens 2, I want to position the lens 2 in the arrow marked space.And also please help me to understand the z axis position of beam splitter, here in the image it is 10mm where the lens 2 located. Why not it considers the center of beam splitter as z position. Help me to understand the z position here. Rays are scattered/Reflected at lens 1, is it un avoided one. Help me on how to avoid this. For reference I have attached the zar.file. Kindly check and suggest any possible way to perfectly define distances with ref to tilted objects.Thank youEbi
Hi, i have a simple question about the materials in the catalog.In order to conclude a simulation study i need to include a layer of aerogelin my design, however i have no clue about where to find it in the catalog. Do you know where should I look for it? In the next days I will also need to include Si as material. Do you know where to find it?Another question (may be this could be very basic, but i’m new to Zemax): in the case some materials are not included in the catalogue, is there any way to include material properties such as index and scattering or absorption length with user defined values?Thank you in advance.
Hello For some reason color pixels by last analysis on my detector is not working….. it remains black even though the detector tab provides a nice gaussian image. I am not sure why it always remains black . I played with alot of settings but it remains black . The zemax sample files however do allow me to view color pixels I have attached the file for reference. ThanksZak
Using the right click, sometimes ‘hide column’ in the LDE works, sometimes it doesn’t do anything. Can anyone shed light on this? Thanks!
Hello all,are there any ways to roughly evaluate optical system inserting just resulted optical parameters such as EFL, distortion, FoV etc, without actually designing the system? The minimum task is to simulate different distortion of 180˚ FoV lenses, it would be ideal to have something like image simulation instrument. Any inputs are appreciated. Thank you.
hello,I have a double pass system and I’d like to know how to do the tolerance analysis, in particular “axial” tolerances (irregularity, power, index,...).I’ve tried to use TPAR operand on my “irregular” surfaces but how do I specify the values for Spherical, Astigmatism and Coma (Par 5, 6 and 7) in the TDE.If I want TIRR = +/-0.5 fringes, what are the Zs, Za and Zc values ?I’ve already used TU** operands for the off-axis tolerances of the elements (see https://support.zemax.com/hc/en-us/articles/1500005575762-How-to-tolerance-for-tilts-and-decenters-of-a-double-pass-system) but it’s not enough.Thank you for your answers.
Dear Sir/Madam,I have couple of questions regarding “Source Diode” setup.1: There is a column “ X - divergence, Y - divergance” in this column either we have to enter half of the full divergence angle or full divergence angle? That is, if laser diode is having 33 degree full divengence in y direction so in “Y-Divegence” column what we have to put, 33 degree or 16.5 degree?2: Similarly we have column for “Delta X” and “Delta Y”, in this column we have to put center to center spacing of the emitters or edge to edge spacing.According to above layout in “Delta X” column we have to put 150um or 225um? Regards,Chandan Maurya
i am learning the optic studio right now. So i have a (Autocad) project to perform calculations from zemax. but I dont know to how to insert a Autocad project to zemax. Can someone who knows help?
I recently need to model a telescope system and I need lights to be reflected out of the telescope system .Howerver ,it’s like what is shown in the picture.It seems that the reflected light is blocked by vertical light? How to solve this?It seems that the reflected light is blocked by vertical light? How to solve this?Many thanks !!
Is there a good way to calculate the spectral response of a multilayer coating? I want to model several different bandpass filters using dielectric multilayers, at various angles of incidence. I know how to simulate a known filter by adding the spectral characteristics into a coating file, but this assumes I already know the spectral characteristics of the coating. I’ve tried adding multiple layers in non-sequential mode, both of varying dielectrics and partially reflective layers, but the spacing seems too small to register properly.
Hi, I am a Phd student at the Paris observatory working on 3D printed microlens on a single mode fiber array. The objective is to design a microlens focusing a uniform beam of 250um diameter into our PM630 fiber (NA:0.12, MFD : 4.5 ± 0.5 µm @ 630 nm) with an optimized coupling efficiency over the 600nm to 900nm spectral band. I have a hard time to optimize the coupling efficiency with POP because, I think, the beam is too fast (warnings in the Prop report: **** WARNING: Pilot beam waist smaller than wavelength detected, scalar diffraction propagation algorithms may be inaccurate). I used the ‘use ray to propagate’ function but as the beam remain really fast at the image plane, I don’t get accurate results with POP and can’t optimize the coupling efficiency with POPD. I could really help to have some leads to follow in order to optimize the coupling efficiency.Regards, Manon
Is there a simple way to make the backside of a NSC Diffraction Grating/User Defined+DiffractionGrating.DLL the diffractive side? I’ve been fighting with rotating objects 180° and then fixing the effects of that but that allows for too many places to get lost and complicate my builds. Is there a setting or trick I’m missing or should I attempt a custom .DLL? Important note: I’ll split these by a _RCWA.DLL
Hi Zemax Support,I use SVG export for the vast majority of OpticStudio graphics, and it is great because it is fully scalable. Sadly, the layout plots (plus a few others) do not support SVG.Bitmap export is supported for these, and OS allows us to export these at high resolution, which is great. I typically use 4k for the width of exported images, see (1) belowThis works great, except there is no control over the surface and ray line thicknesses, as there is in the Layout drawings themselves. See (2) above. A normal OS layout screen will look like: and it’s exported version will look like You can see that the lines are just so thin that this high-resolution file really isn’t all that useable. Would it be possible for exports on the layouts to also use the default thicknesses in (2) of the Preferences dialog? That would give us publication-quality export for the layouts, which you really have to finagle with the code at present.Mark
Hi there,I am trying to model a system as seen in the diagram below where the black line is a circular reflector and the pink lines are the rays coming out of the pink dot. Can I have some insight on how to model this system? I would also like to vary the radius of this circular reflector and the distance from the pink dot to the vertex of the circular reflector.I would really appreciate any help and thank you in advance!
Hello,I have a question about POP analysis at a pixel grid. My system is defined by:a single F/7 lens with the shape of the James Webb Space Telescope (JWST) primary mirror a silicon substrate that contains the JWST lens focus inside it a MIRROR user-defined aperture aft the JWST lens focus. The user-defined aperture is a pixel grid with 25 micrometer wide square pixels and 2 micrometer wide gaps between the pixel. The propagated wavelength is 5.6 microns.The problem I am facing is that, when propagating the wavefront back from the pixel grid (i.e. after the reflection on the pixels) to the JWST lens focal plane, the POP output shows a dark grid with zeros on the projected location of the pixel gaps. This is shown in the attached irradiance figure, where a dark grid is superimposed on the JWST PSF.I have tried increasing the wavelength to 11 microns, thinking that the studied wavelength of 5.6 microns might be too small to interact with the pixel grid when propagating in silicon, but t
Has anyone had experience adding a free space isolator to a Zemax simulation?
I am a student pursuing my post graduation in photonics.As a part of my final year project i am assigned to design a confocal laser cavity using zemax software.Can anyone help me through this.
Hi, I would like to know the illuminated area on the detector produced by any incoherent source like LED. Can anyone please guide me on this. If the detector dimension is bigger in size compared to the illuminated area, will we be able to know, how much area of detector is covered by the illumination. Note: ( Assuming the detector and source are at finite distances)ThanksEbi
Hi all,I am trying to simulate a total internal reflection system (did a lot of them in the last two years).Rays number 1 and 2 pass through the element “glue 1” and appear to stop interacting with the other elements.Ray number 3 does not and so propagate normally.Something with the definition of glue 1 is not ok but I cant find it. Thanks for the help,Nadav
Is there a way to start a clean new lens file from within ZPL? Some of my macros need a clean LENS.ZMX file to start out with.Thanks, Mike
Dear Sir/Madam,I was trying to make a humen skin in zemax, I found a knowlendge base article on humen tissue/skin design: here is the link- https://support.zemax.com/hc/en-us/articles/1500005579202-How-to-model-the-human-skin-and-optical-heart-rate-sensors-in-OpticStudioIn this article all the related values for humen skin model is given, like refractive index, scattering anisotropy (g), u_a, u_b(please refer to the above link). From these given data I can calculate the “mean free path”, “transmittance” by the simple formula given there in article. I had manually calulated mean free path and transmittance based on the values and formula given there in above attached article. I had put all this claculated under “object properties” “Volume Physics” with “DLL defined scattering” to have scateering from different layers of tissue/ skin so far so good,But, for verification of my design when I analyzed these values in the zemax file attached there in the above attached article, I saw that,
Hello,I was wondering if there is a way to coherently sum POP results, for two different wavelengths, having used the POP “use polarization” option in both cases?According to the OpticStudio user manual, page 1154, under “Use polarization” it says that “Because these 2 beams cannot be coherently summed, any complex field data for the output (i.e. real, imaginary, or phase data) will be set to zero.”In my case I want to coherently sum the electric field information for Ex and Ey for two wavelengths. However, I am not sure if this is possible since the phase information is cleared at the end of the POP simulation when using “use polarization”.Thank you in advance,Yannis
Dear all,I’m trying to create a multi-configuration system with two set of fields. Each set of fields will focus onto an image surface, and therefore I’m having two image surfaces after finished the initial configuration. However, the two image surface is not ideal. I would like to control and combine them into one image surface. Is there any idea for doing that?Attached picture shows what exactly I’m trying to achieve. IMG1 and IMG2 are two image surfaces corresponds to different set of fields, and I wish to combine these two surfaces into one perfectly aligned image surface. Thanks for your time!Best wishesDaoming
I just got v22.1 installed and it runs very slowly. Is there an issue or setting that I should be aware of? [Edit: moved to more appropriate forum category]
