Currently running OpticStudio 20.2 Professional. Trying to use the Tolerance data visualization functions (Histogram and Yield) for the first time, but they are grayed out and non-functional. The tolerance data viewer is working and displays the results data set. I have run a short Monte-Carlo set and saved the files. How to I engage the Histogram and Yield functions?
HelloI am having problems running a tolerance analysis that only uses the TEZI operand. I get the error message that says “TOFF requires surface 0 to have a physical sag” which makes no sense. You can see the screen shot in the image attached. I think this is a bug in the software.Any ideas?RegardsDiego
Dear all,I'm looking for a quick way to retrace rays in OpticStudio (“Clear & Trace”) that doesn't require 3 mouse clicks. A button or shortcut doesn't matter. My current workflow is:open the modal dialog Ray Trace Control, hit the button close the dialog knowing that I'll have to reopen it in a couple seconds after adjusting parameters.The simplest fix would be to keep the Ray Trace Control dialog always open, but it's modal so it locks the main window while open.Any good advice for iterative processes involving ray tracing?Thanks, Matthias
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,...). The cha
Dear Support team, Can you please assist with the below error? I am trying to plot RAID operand value vs Y-Filed angle (-1 to +1degree). But the value in Universal Plot and Merit Function Editor does not match.Could you please have a look at the attached files and let me know the correct setting for the universal plot. Can you help to take a look at it and advise?Thanks in Advance!
I am modelling a laser position detection system. I wanted to know if OpticStudio comes with commercially available position detectors like quadrant detectors. If yes, any leads on how to find them in zemax. If no, how does one go about a situation where you have to use a commercially available detector in Zemax.
Hi,I created a 2D simulation of a waveguide in COMSOL as shown in the figure (semiconductor laser).semiconductor laser simulation in COMSOLit is an intensity plot showing the electric field at the edge of the waveguide. From here I can extract x,y and z (electric field) into a .txt file. How can I import this data into OpticStudio? Thank you
Dear all,I’m working on a project of ultra-precise micro-arcsecond relative astrometry space observatory (Theia). Especially, I need to map the image plane (0.5°x0.5°) with a very high accuracy. For instance, I have to study the variations of positions of the PSF (with CENX/CENY) due to some perturbations (distortion, tilts of the mirrors...).By default, the number of fields is limited to 2025 for my premium version, but I would need 100x100 fields.It’s rather easy to generate such a new grid, but the parameter “i” (field number) of CENX/Y refers to the (default) field table.Is there a way to use CENX/Y with this new grid ?Many thanks,Thierry.
Hello everyone, I’ve been racking my brain to try to figure out the image aberration balance method with unknown lens design data method, which isthe camera is put at the final image plane, the current final image is not so good. the problem is the there is an unknown design in this optics train, so I can neither adjust nor redesign the latter components to balance the final image aberration. I come up with a method which is: i put an image aberration sensor at the first image plane, the sensor would read out the first image aberration in terms of Zernike coefficients, then I start a new design, i put a dummy surface which contains the first image aberration in terms of Zernike coefficients at the first image plane position. and then I can adjust or redesign the latter components in this optical train. Do this method make sense?
Hello,I’m trying to design beam homogenizer and checking several concepts: rectangular rod and fly’s eye lens.In my case the source is quite large, 10.4x7.5mm.I looked at Zemax sample file: Digital_projector_flys_eye_homogenizer.zmx.The source size is 0.25x0.25mm. Up to about 1x1mm the design works good. Increasing source size decrease the beam parallelism hitting the fly’s eye which reduce dramatically performance.Do you know if this concept can work with larger source as in my case: 10.4x7.5mm.s quite large, 10.4x7.5mm.I looked at Zemax sample file: Digital_projector_flys_eye_homogenizer.zmx.The source size is 0.25x0.25mm.

It's a simple error, but I couldn't solve it, I want your help. It says "Cannot Open File" to the file I am trying to select from Glass Fit Tool (It Also shows/selects the Data File as only “None”.) I uploaded the file to the GLASSCAT folder and made the names the same even in Glass Fit Tool. But it says “can’t open file”. Thank You,Fhurkhan
Hi all,Thanks in advance for putting your advice to my post.I am simulating a microscopy in sequential mode which contain a tube lens from Thorlab. The tube lens provided by Thorlab is in black box. I want to transfer my simulation design from sequential to non sequential mode. Can I do that? Is it possible to use black box in non sequential mode?Thanks.
Imagine that you are given two cameras and no information about them are given. However, you have all the technical tools in hand to compare their images and find whether their performances are the same or not. To simplify the problem, both cameras image a USAF-1951 chart. Question isWhat factors should be considered to verify two cameras are identical?I would say their Modulation Transfer Function across the object and for all wavelengths are enough for this comparison. Am I right?p.s. Let's assume that we only care about the image quality at the same imaging condition like same iso, same f#, etc. given that we have access to all these settings and cameras are not defective (sensor performance is ideal and not bad pixels). Thanks
Is there a way to specify an adjustment surface relative to another surface for thickness variation. I am developing a custom script to perturb surface #1 thickness and I would like to specify surface #6 as the adjustment surface (I am not sure if calling surface #6 as compensator surface is correct) Basically, I would like to implement the functionality of the TTHI command using ZOS-API. TTHI command: Surface #, Adjustment Surface # (Tolerance on thickness or position in lens units, with optional adjusted) Thanks - A

My optical setup has fiber laser output which collected and collimated by collimating lens and then focusing lens(Plano convex) . And then, I have system of Galvano mirrors (Maximum scanning angle ±22° ) for 2D scan over square field area. So, I am observing spot diameter for center and corner position of square field area(250*250 mm^2) using feature Paraxial gaussian beam. Here, I am attaching Spot diagram and paraxial gaussian beam data. Please note that, configuration 1 is for spot in center position and configuration 9 is for one the corners position. I am also attaching 3D layout for better visualisations. I get same value for laser spot diameter center position as well as corner position of image plane. Theoretically I should get larger value (and non-circular shape) of corner points than center because path length for beam increase for beam as shown in spot diagrams. But paraxial gaussian beam data shows similar value for configuration 1 and 9(in fact for all). I would be gratef
Hi!I am a student learning Zemax and optics as a field. I have been working on designing an Ellipsoidal Reflector Spotlight (ERS) in OpticStudio and am having trouble creating an ellipsoidal surface to serve as the reflector. I have tried using standard surfaces and searching online to find any information that would help me to do so, yet I have found very little. What would be the easiest/most efficient way to create this object?Thank you for your help in advance!
Hi,I am a student of Optics.I am trying to simulate Lenticular sheet (cylindrical lens arrays in a sheet form) based model.I am able to create a similar model in non-sequential mode (see attached file) but I am NOT able to create or configure the effect of Lenticular sheet of making things INVISIBLE in near vicinity while allowing the distant background to be visible, through simulation.Please suggest & advice as how to simulate the object alongwith background & subsequent effect from the view plane.RegardsGaurav
