Hello,After following the next article: The easiest way to tolerance an off-axis mirror I have been struggling to manage the tolerances in my system since it has 2 different OAPs and as in the example, I have set one of them as the global coordinate
Is Erin's guide (linked below) still the easiest method? I've just learned about the new nesting feature, but that's not an option for Pro users.https://community.zemax.com/people-pointers-9/the-easiest-way-to-tolerance-an-off-axis-mirror-4756
I have implemented a simple system composed of:Diode Source with 2deg divergence in x and y; Diffuser implemnted with cylinder volume with a single scaterring surface following a gaussian model with sigma = 0.27 Polar detector to monitor the angular
Hi all, Don’t ask me how I got there… but I found a possibly undocumented (or not well documented let’s say) behavior of RemoveWavelength in the ZOSAPI (SystemData.Wavelengths).In the user interface, if you keep removing wavelengths from the system,
I am in non-sequential mode trying to design coupling optics to fiber couple a Lambertian source into a 980um/0.57NA fiber. After completing my design which consists of two even aspheric lenses, I want to perform a tolerance analysis. In sequential
Hi all,First things first, I am still using Zemax 2012, so this may be a limitation. I have a relatively simple setup: input fibre, half ball lens, PCX lens to collimate a beam, the beam passes through a test glass, and is collected onto an output fi
Hi everyone!I've built a user extension called Wavefront Reconstructor for Zemax that reconstructs the wavefront map directly from an NSC ray trace. If you've ever needed wavefront error metrics in Non-Sequential mode and found yourself stuck, this m
The manual states that ISFN returns a paraxial-only f/# and WFNO returns a real-ray f/#. Nothing is said about ISFN accounting for vignetting. WFNO allegedly accounts for vignetting following a SETVIG or SVIG operand. However, I’m not seeing this
Does Zemax have the internal to export the envelope of beam footprints on surfaces to a mechanical engineering file?
HiI am trying to analyze scatter contribution in my imaging system for off axis mirrors using different surface roughness. For example I have calculated the A, B & g values for 10nm surface roughness and used those values to create an ABg file in
I am using us_array.dll to represent the lenslet array in sequential mode. Is there any way to rotate the lenslet array by an angle?
And also, how do I know which one to use when comparing against real life lenses and optical systems?
Hi All,I am currently designing a low‑cost imaging lens for a sports application. In my lens model I use the REAY operand to control image height, the RAID operand to control chief‑ray angle (CRA), DIMX to control f‑theta distortion, LACL for lateral
Hi all, unfortunately, I have a serious problem using Zemax. Since two days, Zemax (2026 R01.1) freezes completely after opening. I am currently in close contact with my IT department, however the problem has not been found so far. It seems that oth
