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 everyone!If you have ever tried to find a good reference for modeling a beam splitter in Zemax, you have probably noticed that most examples either go the Non-Sequential mode, which means losing access to aberration metrics, OPD, MTF and all the s
Hi guys!I am working on a tolerancing analysis of an optical system that includes a beam splitter, and I have come across a coupling issue that I would like to understand better.In the nominal configuration, all elements are centered and the system i
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
From this KB it is clear that we can pivot an element about any arbitrary pivot point in space. This is Ok for intermediary optical elements in the optical chain but breaks when you want to pivot either the Object of Image surface.Here is a an exampl
