Using Extended Scene Analysis > image simulation, settings:pixel size=0.02X pixels=3000Y pixels=1000After Save as, we can get the picture as below,but this image simulation result is limited by screen size. Could I get a 3000x1000 pixels image(bmp)?Thank you~
Hi! I try to optimize an human eye model and I am not sure what is going on… The RMS of spot diagram of normal model is a little bit over 3um and after the optimization it is over 17um, and the Seidel coefficients are higher than before optimization.Can anyone help me understand what is the problem of worse RMS and how can I prevent it? I tried to use different Image Quality types and it didn’t work.Thank you very much!
Hey Zemax team,I was running a Global Optimization today when Malwarebytes decided to quarantine OpticStudio.exe and the link on my desktop to it:I simply restored them from Malwarebytes’ quarantine, but you should register this as a false positive with Malwarebytes to prevent this happening. Lots of organizations won’t simply release files from quarantine as easily as I can.Mark
I was trying to run the ‘Interference Example 2: A Mach-Zehnder interferometer’ simulation file from the Zemax Opticstudio directory (non-sequential mode), but I couldn’t see any power redistribution between the two output arms of interferometer. The intensity pattern distribution in one arm should be complimentary (negative) to the other one. But it is not happening in simulation. In a perfectly parallel beams with zero divergence, I would expect change in power splitting in output arms with phase difference. That is not happening in the given sample simulation. Please share your comments/explanations for this issue.
Good afternoon, dear colleagues. I’m working with optical testing of the convex aspheric mirror. In the interferogram simulation I’ve got stripes like it is shown at the picture. There is a strange white circle at the edge of interference pattern. On the Optical Path figure you can see something like a break of the plot. Is it possible to fix this wavefront break?I use Binary 2 surface to model diffractive optical element (corrector of spherical aberration). Perhaps, it’s an approximation error of the wavefront, because this surface use polynomials to set a phase shift. Thank you for the future answers!
Hi Zemax I recently implement the Lidar system simulation successfully by referring to the tutorial below.https://support.zemax.com/hc/en-us/articles/4408930472467-Modeling-a-Flash-Lidar-System-Part-1 These days, we are discussing with lens manufacturers to realize our Lidat system.However, it is said that they can provide lens data only in the form of a zemax black box lens. Is there any way for me to analysis the Lidar system using black box lens data?Although many attempts have been made, the NCS mode could not use a black box lens. Best regards,
Hello,I am currently trying to use a flat-field concave-gratings in an optical spectrometer setup.The latter has improved shape and design so that the grooves are neither parallel nor equidistant. The main purpose is to minimize astigmatism and coma.(typically: https://www.ssioptics.com/product-category/diffraction-gratings/flat-field-concave-gratings/)I am wondering which procedure I should follow in Zemax to create this type of Grating shape and/or if anybody else worked using this king of gratings using Zemax?I am working in sequential mode since it is the one which I am feeling the most confortable with. I used the surface type diffractive grating to create my gratings combined with a concave curvature. However I am quite sure it is not the best way to simulate it, and I will certainly not have a proper estimation of my astigmatism and coma.I am open to invest time to learn non-sequential mode if it is needed.Thanks a lot in advance for your help and suggestions!
Hi,I am trying use ‘decenter of a lens’ as a compensator in Tolerancing. For that i have made coordinate breaks before and after the lens that i want to decenter. Then used the tolerancing operand CPAR and used the first coordinate break as the surface and parameter as the x and and y decenter. My question is will the pickup solve on the second coordinate break will cause problems when the Sensitivity based tolerancing is carried out.Is there any other method to use element decenter as a compensator in tolerancing analsis. Thanks in advance.
Dear Zemax Team,my optical system is a mixed POP and geometric propagation model, i.e. I have checked “Use Rays to Propagate to Next Surface” in the Lens Data Editor Physical Optics dialog for parts of my optical design, where I don’t expect significant diffraction effects, also improving processing time and avoiding phase aliasing effects.The tolerance analysis adds Dummy surfaces into the design, e.g. for the TEDX operator, which is convenient to see e.g. in the MC_Best.ZMX file.I have noticed that the setting “Use Rays to Propagate to Next Surface” seems to be not set for the dummy surface as in the original lens data (i.e. it is unchecked, althought the original lens data was checked). In my interpretation this means, that the propagation of the dummy surface will be, if I do a physical optics run, as POP propagation, not ray propagation. As my resolution at this Dummy surface is not properly set (or cannot be achieved), the propagation results will be significantly altered if I pr
How to evaluate the a manufacturing difficulty of surface kinoform (binary 2)?
Hello Zemax Support Team, I’m trying to model a volume hologram in a film inside a glass substrate. In particular, I’d like to be able to calculate the diffraction efficiency of the structure. However, the system seems to have an unreasonable polarization dependence which causes energy to not be conserved for some polarization states such that {input_power ≠ diffracted_power (1st order) + transmitted_power (0-order)}. I am using the volume hologram feature (set to 1) in the Hologram Lens object in non-sequential mode. Collimated input laser beam is normal to the glass and the outcoupled beam totally internally reflects inside the glass substrate upon diffraction. I have 2 monitors: 1) color detector capturing the 0-order transmission and, 2) color detector capturing the 1st diffraction order. X-linearly polarized light and Y-linearly polarized light produce different diffraction efficiencies, as expected. However, for linear X polarization the sum of the 1st-order diffraction and 0-ord
My team is currently looking into improving our stock optics features, and we want users’ feedback to help direct our efforts. If you use off-the-shelf optical components in your design, we’d like to hear from you!Please comment below with a summary of how you use stock optics in your design. In particular, I’d like to know your answers to the following:What are the types of systems you design using stock optics? Within those systems, which types of stock optics do you use (e.g. lenses, filters, prisms, splitters, etc.)? Describe your design workflow. At what point in your design do you start considering stock optics, i.e. do you start with specific optic(s) you already have in hand or do you wait until the final design and then search for the optics closest to your specification? After you have identified the optics you need for a system, how do you search for each component (for all types of components, not just lenses)? Do you tend to order from one specific vendor or shop around mu
Hello Zemax users,I started using a Zemax optic studio premium version (21.3). I am from University of Virginia and want to understand the reflection, scattering and transmission through a glossy paint surface (~50 micron thick) after MIR laser irradiation (10 mm collimated beam) on it. I am unable to find the paint (polymeric) material in Zemax catalogue. Also tried to put coating on plane glass but unable to do. Is it possible to simulate scattering data for 2.7 um wavelength on paint? If yes, kindly help me as I am a new user. I am considering Source rays as source, Rectangular volume as a sample and two detector rectangles as detector surfaces. Am I doing correct? Can we change the angle of incidence at 45 degree?
Dear all, How to design a paint materials (thinfilm) incorporated with TiO2 nanoparticles for scattering? In coating catalogue I could not find similar to our material.Thank you.

I want to measure the amount of power on a surface between particular angles. I used a rectangle detector which parameters 12-15, in the user manual it says it work only for radion intensity. Usermanual: The minimum and maximum x and y direction angles in degrees. These settings are used to control the sensitivity of the detector to rays incident upon the detector at an angle when displaying radiant intensity or radiance in angle space. The default setting is -90.0 degrees to +90.0 degrees in both x and y directions, which allows display of angle data for all rays striking the detector. If the angular range is set to cover a subset of the possible incident angles, rays that strike the detector at angles outside the defined range are ignored ONLY for radiant intensity and radiance in angle space displays. So I used the macro function: Ptotal(i) = NSDD(1,17,0,2) Where I should get the total flux in angle space for all pixels. But this still hold the default value of +90° to -90°.
Hi,I am setting up a seq and non-seq mix mode, and using Prism45.POB as object for non-sequential component.it requests prism45 to be 8mm, I don’t know where I can input to set up this specific size.Thanks in advance.Ying
is there a simple way to assign the same scatter model to all surfaces/faces of a CAD object in Non-sequntial mode. My object has 50 faces, if I modfiy it in CAd and re-import I don't want have to re-assign face by face the same scatter model.
Hi! I know Zemax has up to 231 Zernike terms for Zernike Standard sag value but I can’t find the Polynomial formula for terms higher than 37. Is there any way I could find what is the mathematical formula for higher order terms? thanks!
HI community!Actually i was going through the THOR Lab manual for FTIR spectroscopy and got stuck at understanding the relationship between resolution expressed in wavenumbers (R cm^1-) and in nanometer (R(nm). In the Table-2 (link given below) of that manual, can someone explains the conversion formulae used for calculation ? FTIR document reference
Hi,I am doing ray tracing reflected at a TIR prism and faced a problem that beam stops at a certain surface as shown below. Any one can help to solve this ? [Mod update: moved to more appropriate forum]
I know a mirror surface without coating is treated as 10um-thick Al coated. If I apply mirror to a surface in the meanwhile also apply taper coating, how does ZEMAX handle the coating stack. In this case, what would be the substrate? Will POP work for this coating stack? Thank you very much.
Hello,I was wondering if it is possible to have an older version and the newest version installed both on the same computer, and if I then will be able to run them both.This because I experience a bug (already reported) in the newest version, but my colleague does not experience that bug in the 2019 version, so I was thinking of doing this specific design in the older version.Kind regards,Rick
Does OpticStudio have some type of camera view similar to the CAD camera view in SolidWorks? Basically, if I have a non-sequential layout, can I place a camera somewhere in my layout and see what the camera would see? Thanks
