Hi, All surfaces have some amount of particulate contamination (i.e., dust) that increases their BSDF above the level predicted by their surface roughness. It happened in a clean room when we are aligning a optical system.I would like to simulate this scattering using a MIE model, for that I need to give mie properties to each optical surfaces (mirrors in our system).is possible to give mie properties to each mirror and evaluate particulate contamination?Best regardsMiguel
Hi all,I need to define the transmittance of a material and I have as input the emission of the source in terms of CIE 1931 x, y and as output the measurement with the same standard.Inserted the values in the Source Spectrum Plot of OS, I obtained the spectrum for 100 wavelengths of both the source and the target.How can I combine the weight of each wavelength to generate the absorption values to be included in the material catalog?I attach the Excel file used for the calculation. Thanks in advance.
Hi everybody,i put an turning mirror (==like fold mirror in SC) in my optical system in NSC. I realized this with rectangle object ant mirror material under 225° tilt about x. But the following optical parts( 2x lenses) after turning mirror now are off axis and parallel to turning mirror. I corrected that again with 45° tilt of next following lens. Only problem is now, that all optical parts after turning mirror are all off axis. Is there any option like fold mirror (in SC) in NSC?thank you in advance.
Hi all, I am exploring designing a microscope tube lens and I am not sure the best way to setup the idealized output from an infinite conjugate objective lens to match the parameters of an off the shelf objective. The information provided on the objective is magnification,NA, working distance, and field number. Can I convert these to field angles somehow? What is the best way to set this up? Thanks!
I want to understand how the OPDC built-in function in ZEMAX is calculated, and I hope to reproduce the OPDC calculation through ray tracing and programming or other methods.The focus of the question is the specific operation method. I already know that opdc is the subtraction of the reference sphere and the backward tracking distance.I would be very grateful if you could answer!Sincerely，Nancy
I have a question about simulating integrating spheres. There are 2 configurations:Integrating sphere attached to monochromator with QTH light bulb where only the output light from the integrating sphere is of interest, how it comes out from an X inch diameter sphere with Y inch port aperture. It doesn’t matter how the light gets into the integrating sphere, as long as the output light is uniform. The goal is to use the output light in further simulations such as what the light pattern would be after light passes through pin holes and such. An LED light source with filter wheel is attached to integrating sphere, it is important to calculate system efficiency so input light needs to be tracked as well as output light. The goal is to better approximate system efficiency by accounting for light that goes in and out (desired output as well as the input port where LEDs are) of the integrating sphere before it escapes or is absorbed.Does anyone have recommendations or examples in non-sequent
Hi,I would like to measure the beam diameter after focusing lens. My requirement to measure the beam diameter at different location along the focusing length. As shown in image, I am using measurement tool , it does not look precise, some time with minor mouse movement value is changing. Please suggest correct procedure.
Microlens ArrayHi,I am research student at University of Virginia, I am making micro lens using laser processing and was wondering if Optics studio can be used to simulate light propagation/ray tracing through the micro lens. We have an array of microlens, each being 40 microns in diameter. We also want to know about the sequential and non-sequential.My university email is firstname.lastname@example.org, if anyone from technical side from Zemax can provide some contact my research advisor and my colleagues have some more questions regarding capabilities. We are willing to get a license for Zemax as we work with a lot of optical device and applications.Best,Raju Gottumukkala
Hello,I'm trying to simulate the image quality of a 3D printed optical lens, so I experimentally used a USAF 1951 test target as an object. To compare the results I'm trying to implement this optical system in sequential mode in zemax, so I needed the same object that is the USAF-Target image, but I don't know how to add an external image in zemax.Could someone tell me if there is a way to add an external image for image simulation?Thank you very much in advance!
I am a student trying to make use of OSRAM’s manufacturing LED data.I downloaded 5 different coloured LED bulbs and tried to use them on a single file after saving all the manufacturer files (e.g. DAT) into the appropriate folders.However, when I open the NSC model/Ray Trace the LEDs do not appear nor are any rays traced.
Can someone point me to a model using a VIPA (Virtually Imaged Phase Array)? I keep getting tangled up in transitions from pupil to line focus to image, and I think someone must have figured out a better way. For reference, https://lightmachinery.com/optics/custom-optics/vipas/.Thanks,Eric MentzellNASA Goddard Optics
I import a CAD assembly SolidWorks and explode it(SAB format) but when do the ray tracing and make the opacity of the CAD files to lower , I set all faces of the CAD files to the mirror and after ray tracing I see that rays are reflected internally inside the CAD file. like it is a shell and not a solid!! but it is solid. how can I solve this issue?
Good evening.I’m investigating whether it would be possible to optimize the optical axis direction of a birefringent material which forms part of a non sequential geometry object. Does anybody know if there is some way to indicate these fields as optimization variables? May be using the ZOSApi if it is not directly accessible through the graphical user interface?I’ve seen that material optimization is not supported in NS mode but maybe the optical axis direction can be optimized, since I’m not changing the material through the optimization, but a continuous property of always the same materialThank you very muchRegards
I’m getting Error 194 with zero information about why. After some digging, I discovered that this is the error I was getting when running in Mixed Mode and it couldn’t find a glass I entered in the non-sequential spreadsheet. Please correct this so that the same error message is displayed whether the missing glass is in the sequential or non-sequential spreadsheets.Getting any error in Zemax without at least the courtesy of even a brief diagnostic message is not the mark of a truly finished, professional, costly software product. Please review all error messages and add some brief text for each that will help users diagnose and fix the errors. Error 194 tells us nothing.
Hello everyone, While I have been searching on cartesian oval on the web, I have encountered that Descartes discovered the cross-section curve of the perfect lens, assumed to be a surface of revolution, is a fourth degree curve known today as the cartesian oval. The paper can be reached via the link below:https://www.semanticscholar.org/paper/Decartes%27-Perfect-Lens-Villarino/049deec93a061162436f0ee7e0d5767d3a92e83eHere is my question; if the perfect shape of a lens that will focus all rays from one radiant point source to one single image point, and that perfect shape is a surface of revolution with a fourth degree curve; why does ZOS aspheric terms are available more than a fourth degre? Or otherwise, isn’t a fourth degree surface sufficient to make a perfect focus? Best regards,
Hi all, I hope everyone is still doing well. Following on from my last post (see “Related topics”) I have been trying to model an imperfect axicon tip for a 20 degree axicon from Thorlabs (AX2520-B). I have been using the standard surface within the lens data editor to do so.From the instructions within the help function for the standard surface, I have calculated the conic term to be -8.54 and have estimated the radius of the tip curvature to be approximately 30 micron (as the help function states that this value is not too important as long as it is significantly smaller than the total aperture of the lens, which it is in this case).Having placed surfaces at every 0.1 mm from the (now imperfect) conical tip across its approximately 7.5 mm Bessel zone length for the 2.6 mm 1/e^2 input beam diameter (giving a total of 82 surfaces in the attached files), I only observe miniscule oscillations in the peak irradiance on axis, contrary to my experimental observations (as well as that from v
I have a problem modelling the transmission of different materials in Non-Sequential mode . To solve the problem I have set up a simplified model. I uses a Source Gaussian, a Detector Rectangel and placed a Cylinder Volumen with different Materials between source and detector. However, the material did not show any loss of total power in the Detectorviewer.Any ideas?Thanks Jannis
