Can use GENC at the surface other than image surface?

I would like to use GENC to find the GEO radius. it seems I can only get that data at the default surface-image surface. How can I get that data in other surfaces, such as the surfaces close to image surface?

Is there way to view CIE x, y map on illuminating target in NSC?

My question is exactly as title above. Detector color gives true color map view on it with just X, Y, Z values in raw text data. But it’s more useful to have that as CIE x, y or u’ v’ data set. I know how to convert between these values using Excel, but if Zemax can generate, display that it would be a lot more convenient. Mine is 2024 R2 Preimium but I don’t see that option yet.

ISO Element Drawing: open issues

I'd like to point out some mandatory features which, in my humble opinion, the ISO Element drawing utility lacks. I'm probably referring to all well known issues, but still, I believe them to be of paramount relevance to be left unsolved over the years. 1) support for triplets. 2) xml file support for doublets/triplets. More on this, I report a sneaky behaviour of the current feature: if a doublet design is saved, no error is reported by OpticStudio and an empty xml file is saved instead, so that the average user can believe its manually inserted data are securely saved, but actually they are not. When opened, such xml file just reports the string 'XML output is not currently supported for doublets'. 3) drawings saving in a native vector format, such as pdf or svg. At the present time an external pdf printer sw is needed to do so, often with unpredictable results. The same request holds for every graphic output of OpticStudio (diagrams, histograms, plots,...).

using red key on a new computer

I have a Zemax 16.5 SP3 with a red key. I want to use it on my new computer with Windows 11. After installing the Zemax 16.5 on the new computer and plug in the red key, there was no key information in the Zemax License Manager and I couldn’t run Zemax. The red key was light on for a couple of seconds and became light off.Could anyone please assist? Thanks!

How to create an input beam with different x and y divergence

Hi Everyone, I am struggling with creating an input beam that has different x and y divergence. The beam located at object space is elliptical and diverging very fast in one direction and slowly in the other. Is it possible to use object space NA and vignetting to realize? Thank you so much!Di

How to set the Y start order and Y stop order of grating object via API?

I got an issue when I set the parameters of grating object via API.When I set other parameters of grating object via API, the preset Y start/stop order will change to 0 automatically.And I am trying to find a function to set the Y start/stop order in API, it turns out there is only property named start order can be set.So this issue is the Y start/stop orde will be changed to 0 automatically when I am setting other parameters, and I cannot set the Y order via API.

How to model surface scatter for Mold-tech or VDI textures

I often need to model lenses or diffuser plate with some texture grains applied on some part of it. Normally it’s called out as Mold-tech or VDI texture grain, which are commonly used for surface diffusing optical elements.The question is how do I apply that correctly in the Zemax optical model. Is there any DLL library for that or should I use Gaussian or AGg to approximate that? Problem is there is no available data to correlate such scatter model to Mold-tech definitions.

Error message when uploading a grid sag file

Hello, I’ve created an eye model based on real measured patient data. The anterior cornea is a measured XYZ data. The resolution of the file is 0.02 mm. When trying to upload this file to the system I’m receiving an error message as followed:AllocGridPointers: ‘newsize’<=0 I’m trying to understand why this happens and how can I fix this. Is the resolution of the file is to small? or there is something else I’m not taking into consideration? Thanks, *The dat file is attached in the ZIP folder

System throughput

Hello,I was wondering whether the tools available within zemax would enable assessing the throughput of an instrument. Specifically, I can estimate the number N of photons gathered in a pixel placed at the FP of an instrument as: N = R * p**2 * pi * wave * T / (4 * F#**2 * h * c) where R is the scene radiance, p the pixel size, T the system transmission, h and c are Planck’s constant and speed of light. My assumption is that, at first order, I can simply use WFNO operand value along with the transmission factor from the transmission analysis since the latter takes into account all coatings defined as well as the vignetting defined by any aperture in the model. Or am I missing something? Thanks in advance for any insights,Regards

Non sequential

Hi, i have a optical design simulated in non sequential. I want to convert it to blackbox but unfortunately it is not happening as there is no option to convert to blackbox. Is there any way to hide the design without using blacbox. Since am using some CAD parts its not possible to convert to sequential. In other words is there any option in non sequential where i can hide all the design information?

Concave mirror lens system design and reservation of field of View ?

Hello, Not quite sure this community is still active?I want to have a lens system which can form the image from infinity to a limited distance as show below. As you can see that the concave lens system will reduce the input field of view. How can I have a compact concave lens system which can form the image from infinity to a limited distance and keep the same field of view as the input. Can you have some suggestions or initial configuration for recommendation?Thank you ! BL

CAD Part Zemax Part Designer

Attempting to load a CAD file created from Part Designer into NSC component editor, per the user manual the object type drop down box one of the choices is supposed to be 'CAD Part Zemax Part Designer' that then is supposed to point to the .ZPO file created in Part Designer, it doesn't have that choice, in fact the CAD files are only the typical STL and IGES type of files.  I have OpticsStudio Professional 20.2.1.

Want to annular lens design and see the paths inside the minimum radius and through the lens

Hello all, I have some questions about designing the optics. In sequential mode, I change the aperture to ‘Circular aperture’ for the annular lens. But ‘Circular aperture’ blocks the lay in the inner hole. I want to know how to make an annular lens that can pass the lay into the inner hole. It’s no matter sequential or non-sequential mode. Thank you,

How to convert CodeV Decenter type "Global Coordinates' into Zemax

I have a surface “OBJ_EP’’ in Code V. Its thickness is 7.049 and the decenter of it is below What I did in Zemax: create 3 coordinates breaks ahead of the surface as image below. The first one is coordinate return Orientation XYZ to the global reference surface “ILL_IMS” as CodeV. The second is YZ shift. The final one is tilts (I am aware of that the tilts sign is opposite b/w CodeV and Zemax)However the convert result does not look right. Can anyone help? thanks

non-sequential mode: hyperhemispherical object

Hi there,I try to model a hyperhemispherical object in the non-sequential mode, however, Zemax won’t let me to do so. I get an error saying “cannot create object because there are too many faces in the source objects”. I tried to use the Boolean operation and substracted a zylinder object from a sphere. This works for truncated spheres until a hemisphere results. If I shift the zylinder further and the result would be a hyperhemispheric object the error occurs. Is there another possiblity to create a hyperhemispherical object? Many thanks for your help! :)

Image plane in a STOP analysis workflow

The STAR Module in Ansys Zemax OpticStudio allows users to import FEA datasets and analyse their impact on optical performance. In some optical systems, the load cases on the image plane can significantly affect this performance. For example, a lateral shift of a detector or receiving fiber due to the expansion of the housing in an optomechanical system may have a considerable influence. I`d like to briefly demonstrate how this can be addressed within a STOP workflow using Ansys software packages:On the left, as a starting point, we have an optimised optical system for a transceiver. These types of optical transceivers are widely used in fiber optics communication systems. The geometry is then exported into a CAD environment, where the housing for the transceiver is designed. At this stage, we also design the initial section of the receiving fiber, which represents our optical image plane, as a physical geometry (labelled as Ip in the graph above). The diameter of this geometry should

OpticStudio crashes when using the tilt/decenter feature in the lens data editor

I have a sequential model that already contains quite a few coordinate breaks. Today, when trying to use the “Tilt/Decenter Elements” button, the software simply closed without an error message after I clicked “OK” on the pop-up window. I now can’t use the function at all without the software crashing. I have tried:- docking all windows- removing all analysis windows so that only the Lens Data Editor is open- removing all solves- using a variant of the same model saved as a separate file (worked for the first element I tried, then crashed after I tried tilting/decentering a few more elements).It seems to work if I create a simpler lens model that has fewer surfaces and coordinate breaks, or if I create coordinate breaks by adding new surfaces and changing the surface type.I have checked Windows Task Manager and saw that the CPU usage and memory don't increase during the crash.I am using version 2023 R1.
