The attachment is my design. I am trying to use Physical optics propagation to find out the output beam size, but POP result is weird when I include a paraxial lens (surface 1) into the propagation and set the gaussian beam waist to be the beam size of the input fiber waist. But when I exclude the paraxial lens(start propagation from surface 2) and set the gaussian beam waist to be the beam width after the paraxial lens, the result becomes more reasonable. Does POP accept paraxial surface? When I define the gaussian beam waist in POP, is the waist location always assume to be at the starting surface? Thanks!
I am trying to optimize illumination lens, which function in merit function editor should I use to control the parameters? not x,y,z, but the curvatures and polymonial coefficients? Is there something like PMGT in sequencial mode? Thanks a lot.
Hi I am designing the microlens using two photon polymerization, showing below: I attached the zar file. I have two questions: 1.How to change the material now with PMMA to IP-S and LLF2 to ITO? The index of IP-S is showing in the next table 2.After finishing the sequential mode design, I will then do the non-sequential mode design. I am planning to use the Even Asphere lens. But in the microlens SEM showing above, there is two things I am not sure how to do: a)How to export 3/4 lens as the CAD file? b) How to make the surrounding structure? That would be great if you could give us an example file. Thank you!
Is there a way to customize the aperture type so the apodization type could be a combination of multiple Laguerre-Gaussian modes. Basically I want to model the output from a multi-mode VCSEL and couple it to a multi-mode fiber (so I define object space NA and apodization type as Gaussian, and use Geometric image analysis for coupling efficiency calculation, but I am wondering whether there is more accurate way to model since the output from VCSEL is not Gaussian). Thanks.
Dear OpticStudio Team, I have a professional softkey license installed on a desktop and I would like to understand if: - the license needs internet connection to work - the same license can be installed on another laptop and used as well there of course with the same number of parellel sessions limitation, e.g. 1 session running on the desktop and one on the laptop Thanks for your help. Best regards Gabriele
I'm trying to simulate a large size but high resolution detector in non-sequential mode. So I need both large number of rays and small pixel detector. But OS is capping my maximum number of pixels at 6000 and maximum number of rays to 1e9. Is there a way to increase those? computation, speed and time are not an issue. It can take as much time needed or the memory. Lemme know if I can change those settings some where to push to higher resolution. Thanks
Hi there, I was just wondering if OpticStudio or OpticsBuilder trial will show in the 'License Manager' on MyZemax? I am currently trying to access OpticStudio over my works VPN and having some issues. So just trying to detemine if the trial has eneded or if its just network connection issues. Thank you!
Hi all. 1. How to locate the stop surface to the focal point of the object telecentric system? There is the only article for the telecentric in image space. (https://support.zemax.com/hc/en-us/articles/1500005488201-Modeling-a-lens-that-is-telecentric-in-image-space) 2. When is the recommended step to enabling 'Telecentric object space' mode when I design the telecentric system? Thanks in advance.
I have spectral flux and angular emission patterns for a unique led source that does not exisit in any libraries. What is the best way to model this source in zemax? My current plan is to use the radial source type and then enter the wavelengths with weighting manually on the system explorer with weightings relative to the spectral flux. Will this achieve what I think it will and combine the data to make an appropriate model of the source? Is there a way to import a file for the wavelengths to avoid manual entry?
Hi, In the opticstudio user manual, we can find some optimization operands,just like DSAG, DSLP. Options for tha data input will be :1-RMS xx value over the surface, blabla.... I'm confused what's the difference and what situation should I use. Thank you in advance!
Hi there, My name is Bin Wang, and I am a graduate student at University of Colorado Boulder. My Zemax key serial number is L116967 and I'm on premium subscription. The problems that I'm trying to solve is to simulate a K-mirror system [wiki page: https://en.wikipedia.org/wiki/K-Mirror_(Optics)], and verify its property, i.e., when you rotate the K mirror by 20 degrees, the output beam rotates by twice of that. In particular, I'm having problems with: 1. I defined 3 reflective surfaces in the K mirror system individually, but how to combine them into one subsystem, so that I can rotate them without changing the relative positions and orientations? 2. I do not want to move/rotate the detector plane when I'm rotating the K mirror system. How to achieve that? Best regards!
Hi, I had the 2020 version of OpticsStudio but recently I started getting some errors while working. These errors did not prevent me from doing my project, but they were constantly annoyingly warning me, so I deleted OpticsStudio from my computer with all of its files. When I install the new version and try to run OpticsStudio, it says the files such as 'ABg_Data, Coatings, BulkScatter etc.' I deleted are missing. And it does not working. Is there any way I can completely uninstall and reinstall OpticsStudio? I attached one of the error examples. It says the file is not in the place.
Hi Everyone, I am currently working on a fiber coupling efficiency problem. I have a .zbf that I got from Lumerical as an input mode of my system. I want to propagate this mode onto a lambertian surface and then importance sample the rays that goes to another lens.As an ouput, I want to generate the mode and save it to open it in lumerical and calculate the overlap. I guess there are two differents problem here, first the lambertian surface and the importance sampling. Second, save the ouput mode to calculate the overlap in Lumerical. Thanks for your help. Best regards, Martin
I work in the design of ground based optical systems used in Astrophysics. One effect we frequently have to correct for is atmospheric dispersion. This is relatively straightforward, and in many cases the current atmospheric model built into Zemax is sufficient. However, when working at extremely high resolution (for example in Adaptive Optics) the current implementation in Zemax is not good - the data used to calculated atmospheric dispersion is using data which is out of date - the data from Hohenkerk and Sinclair underestimates the dispersion. Is there any likelihood this will be updated to more recent data?
Hi all, I am trying to simulate beam splitter , and i am using the file at zemax/samples/non-seq/ray splitting as reference. I am intrested mostly in finding the ratio between the transmitted intensity through one of the ports to the initial intensity . How i relate the transmitted data in the detector viewer to the initial intensity? (I_t/I_i) Thanks, Nadav
