Non-Sequential Combining a group of objects into One

Hello, I currently have a set of objects that I use fairly often in my models and instead of me creating them every time with the desired spacings, thicknesses, Etc.. I wanted to know if there is a way to create them once and somehow combine them into one. E.G. Source diode with a specific divergence angle and a rectangular volume with a specific material, X-width, Y-Width and thickness that is some distance form the source diode. Can I package these two objects into one that I can import to my different models? Thanks

objective entrance pupil

Hi,In my scanning laser setup, I use a paraxial lens as an objective f=10 mm, 20x. The entrance pupil (EP) of objective is 10 mm. How to add front and back f of the objective together with objective back focal plane ( which is the entrance pupil). Also, in “the goal” simulation ( at the bottom) scanning rays are restricted by the objective BFP, and it does not work in my simulation.Regards,Marzanna

Ansys Zemax cannot use *.ZMX child files for OFH

Michael Cheng provides a great how-to when using optically fabricated holograms (OFH). I downloaded the associated zip file from his post (here). The files are saved in the ZMX format. When you load the playback ZMX file, it will throw an error message saying that it can’t find the construction files even though they are correctly named in the comment line of the LDE. It appears that the reason is because they are saved as ZMX files and not the newer ZOS file. It appears that this is recent change since as I don’t remember having this issue before I installed the Ansys version of Zemax OpticStudio (currently running 2022 R2.02). I guess this is a bug; however, I don’t know that for certain.Is there a reason that Zemax can’t use the ZMX format for the OFH surface?(Update 1, 2023-02-20): I have done a fresh install and now Zemax is asking for the ZMX format instead of the ZOS format when I load and OFH playback file. I have tried toggling the default file format between ZOS and ZMX; howe

biconic zernike surface, # zernike terms

In biconic zernike surface parameters, there is a “#zernike terms”. Could you tell me how to set up this number if I want up to third order x and y terms? thanks a lot.

Diffractive surface ray direction calculation

I looked at the following article.How diffractive surfaces are modeled in OpticStudio – Knowledgebase (zemax.com)I am confused about how the direction is calculated after determining the phase profile. The article says the cosine of the derivative of the phase difference is added. But that difference is not between -1 and 1 in most cases. For example, if wavelength=400, p=1, p^2 coeff = 1, the change of direction is 400/(2pi) > 1. Can someone explain where I am going wrong here?

PanDao Export

Hey Zemax Team,Thank you for adding the Pan-Dao export feature. This will be a very useful feature, but unfortunately it is not yet ready for prime time. My suggestion would be to move it to Feature Experiments, so suitably motivated users can beta (alpha?) test it. At the moment is appears as a full feature in the UI, and it has a long way to go before it is ready for that.Please take the following as constructive criticism :-) Also remember that I am much more willing to dig into a new feature than you should assume a typical user will be. I actually enjoy this kind of stuff, and do not have a bunch of real work to be getting on with.1. So first of all I loaded the double Gauss and excitedly hit the button, and got a message saying that I needed to provide 'inputs' for surface tolerances in the Tolerance Wizard. OK, maybe I should have known that...bad user. But if it needs the Tolerance Editor to work, the feature should be in the Tolerance menu alongside the Cost Estimator, in the

Laguerre Gaussian beam setup on POP

Does anybody know the way to model Laguerre-Gaussian beam for 01* mode which is doughnut shaped?    I would like to simulate 'VCSEL' beam with its shape similar to doughnut and M2 value 2.1. The Laguerre-Gaunnian beam of mode 01* (not 01) would give similar result, but I could not find the way to model it in Zemax.    For another trial, I have used the 'mixed mode' to simulate M2 value. The beam file was as below. COHERENT !DLL 0.2 Laguerre 0.0 0.0 0.00259 0.0 DLL 0.5 'Laguerre beam'     0.0     0.0     0.00275     90.0 DLL 0.4 'Laguerre beam'     1.0     0.0     0.00275        90.0 DLL 0.4 'Laguerre beam'     0.0     1.0     0.00275     &nb

Head up display design tools

I would like to design a HUD projector to work with a windscreen. I am wondering what the best method for doing this would be, whether to use OpticStudio or Speos. I am familiar with Zemax but have never used it for this type of application. Because I don’t even know where the HUD optics will be located in space, or what their form will be, I need a tool that allows me to define a geometry to give me roughly what I want before optimising. Unsure as to whether Zemax is the best package for that.

Cylindrical Zernike Surface

Hello,Is there a way to simulate the Zernike polynomials on a cylindrical lens? I have a cylindrical lens that is quite long, and with some Zernike terms, it gives a weird shape.This is the basic cylindrical array: But with a Zernike term, it becomes: It seems that the Zernike is applied in X and Y, but I only want it in one of these directions.

Ray tracing on CAD STL files

Hi! I have imported a 3D model of a lens from SOLIDWORKS to Zemax and would like to ray trace it. I am a beginner at Zemax, so I am not sure where to start and how to define the surface, etc..Thank you!

How to create a combined prism in NSC

Hi, I am very new to ZEMAX, may I know how can I build a combined polygon in ZEMAX in NSC mode?For example, I need a combination of two types of material. The 1 and 3 sections use the same material but with different dimension, the second section uses another type of material.

simulation of 2D galvano mirrors in Zemax

Dear Zemax Tech Support Team :)I am new to Zemax (like less then 1 week). I would like to run simulation for 2D galvano mirrors that will be used in scanning laser microscopy. I read/did your tutorials for 1D tilted scan mirror. I wonder whether 2D simulations are possible ( not too complex and complicated) and if so how to start with it.Thank you,Regards,Marzanna

"Gradient 4" Surface Type

Dear Community,I am trying to analyze my system (combination of primary and secondary mirror) for a given temperature gradient. For that I have setup my LDE as shown in the below screenshot… "Gradient 4" Surface is covering the whole system (PM and SM). Since I am working in Sequential mode. I have couple of questions…Is LDE shown in the screenshot is correct if I want to study the effect of temperature gradient from Secondary mirror to Primary mirror (By changing Nx1 and Nx2 Value in Gradient 4 row focus spot shape is varying)? Will the same temperature gradient be applied to the primary and secondary mirror as well, or it is restricted to the surrounding medium only?Thanks.

How to perform tolerancing with composite surfaces

Hey friends, I am wondering how to set up tolerancing using composite surfaces. Basically, I have a composite surface configured with the designed curvature of a lens as the base, and the Grid sag file generated based on errors I measured from a lens using profilometry. I would like to see if I have multiple times of the error adding on the base, how bad the lens performances will be. I was trying to use TIRR but I was confused about how to set it up. Can anyone suggest? Tutorial on ‘Tolerancing irregularity with Composite Surfaces’ was not very clear on this to me.

Location of each element in a circular array of radial sources

I generated a circular array of 16 radial sources using the Object properties in the non-sequential component editor. It automatically generates each at distributed angles in the circle. I need to place optical elements on each and I wanted to ask how can each source’s location be found? Thanks,Niel McCaffrey [Mod note: moved to more appropriate forum for OS-related discussions.]

What is the best way to identify and control intermediate image positions?

This isn’t a fully formulated ask but reaching to the community for any tips or tricks.To identify and control intermediate image planes, I’ve tried adding dummy surfaces with their position driven by a marginal ray crossing [PARY PY=1, Target = 0] in the merit function. This works OK, but it seems computationally expensive. I’d rather just have the thickness be a solve like the ‘normal’ marginal ray solve, which only works for images after the stop…Another topic, more generally, is that dummy surfaces can get in the way of boundary operands by unnecessarily driving clearances. Especially when leveraging the merit function wizard, one must go and find the dummy surfaces each time and remove their operands and/or weight. This there an easy way to ignore boundary operands for dummy surfaces?Thank for any advice,John

Error message when I reverse my system

Hi all,I designed our system in reversed way, started from image plane to object plane. Now I try to reverse the system back that started from object plane to image plane. However I got an error message: Cannot rind rays to yield requested image height. I am not quite sure what is wrong here. The performance is good with reversed design. I used Grid Distortion to check the chief ray tracing, and they seem fine for all fields. Any suggestion would be appreciated.Thank you,Xiaolei
