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
Hello,I would like to model the propagation of a polarized light beam through a biaxial crystal.While methods for uniaxial crystals seem to be well established, I am unsure how to approach this problem for biaxial crystals.How do I handle this case?T
