POP simulation using Toroidal lens

I’m using a lens that on both sides is Toroidal. When making Physical optics propagation, what are the things I need to be aware of in order to make a correct propagation? One thing I noticed is the ‘Separate X-Y’ , any other issues?

Tolerance data visualization - Histogram and Yield icons grayed out and non-functional

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?

TEZI tolerance operand error message

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

Faster way to "Clear & Trace" in OpticStudio

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

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,...).

Universal_Plot value not matching with operand value

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!

Quadrant Detector

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.

Homogenizer

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.

The new Composite Surface is out!

With the new Composite surface it’s now possible to tolerance the irregularity of almost all surfaces in OpticStudio! TIRR, TEZI and TEXI tolerancing operands have been expanded to allow for irregularity simulations of surfaces other than the previously supported Standard, Even Aspheric, Toroidal and Zernike Fringe Sag. Simply use the desired tolerancing operand on any surface that can be used as Composite, and run a Tolerancing analysis as usual. OpticStudio will automatically add the appropriate Composite Add-on to the surface being tolerance and assess the effect of the perturbation against the chosen tolerancing criterion. For more information, check Introduction to Composite Surface.

Can't Open File

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

Non sequential mode: Black box

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.

What factors should be considered to compare two cameras?

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

How to specify adjustment surface for Surface Thickness tolerancing using Python ZOS-API

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

Paraxial gaussian beam data

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
