Hi everyone! My name is Leonid, I am new to zemax and I have a following task:To use a model of the eye in zemax in sequential mode (found in the internet) To model a contact lense which I should “wear” on the eye and to see what our eye would see if I wore this contact lense. The lower surface should be fixed and have a radius of cornea. The higher surface is arbitrary. Contact lense should focus rays on two distances from the source of light - 20mm and infinityHow can I make an optimisation for the higher surface of the contact lense. So, it would both at the distance of 20 mm and at infinity? Now I can only do optimisation for one focus values. How to do optimisation for multifocus system is not clear for me :(
Hi everybody,i am trying to export an ISO Drawing of my lens, which consists of two biconic zernike elements. But the Drawing Element in the ISO graph shows the lens as two surfaces even i choose “show as: Singlet”. Is there any solution to get the lens drawing as shown in 3D layout or it is the zernike surface Bug/problem in Zemax? best regards,Ata
Hi all.I want to get the interference pattern of the beam homogenizer using lens arrays and focusing lens in Non-sequential mode. When we use the beam homogenizer, we can observe the interference pattern on the illuminated field easIly.Gratefully, zemax offers an example file of the beam homogenizer which is illuminated by an ellipsoidal volume source.(https://support.zemax.com/hc/en-us/articles/1500005489121-Fly-s-eye-arrays-for-uniform-illumination-in-digital-projector-optics)However, in this example, the illuminated field is a very 'pretty' flat-top beam.Of course, probably because it is assumed as a non-coherent beam.If so, what if I want to simulate the beam homogenizing system with a real laser source that is coherent or partially coherent?How can I get the interference pattern in this example? Thanks in advance.
Goodmorning everyone.I’m a new user of Zemax.I have a simple mirror system composed by two elements: the first is flat while the second spherical or parabolic. The object is set at 3400mm from the pinhole and it is 1180 mm x 1180 mm. The system works in visible range.Link files Can you suggest a way to define the resolution of the system or suggest papers or discussion about this topic ?
Hi everyone,I am completely new to ZEMAX, I am supposed to simulate a refraction grating with asymmetric gap distances.To be exact, my system should look like this: A laser with 0.5mm diameter illuminates a refraction grating with the 2 alternating slit distances (5 and 10um) and fixed slit width (5um). After the grating, an intensity pattern is created by the interference of the light. I would like to calculate this interference pattern.Is this possible with Zemax and does anyone have tips and ideas how to start something like this?If someone can help me, I would be super thankfulBest, Annika
Hi!I am trying to set a system made of two Fresnel lenses (that I don’t know anything about), capable of accepting +/- 45 deg of source incident angle. I am working in non sequential and I am getting familiar with the optimization wizard. For this specific application I have run an optimization (orthogonal descent algorithm), in order to minimze the RMS on the detector and to have a minimum power of 0.08 W (see Local Optimization Viewer pic attached). The variables are:Thickness of both lenses Radius of curvature of both lenses Coeff r2 of both lenses Frequency of both lenses Conic constant of both lenses z1, z2 (distance between lenses, distance between second lens and detector)This optimization yielded a 25 h process, leading to the results I attach here in the format of pics as well (Merit function editor, Detector viewer and System view).How should I interpret these results? Should I think it is not possible then? Can I trust this system? Thank you for your precious help,best,Giuli
Hi everyone!I’m new to Zemax and this community and I hope someone here can help!I am trying to design an Acousto-Optic Modulator for an experiment in our lab. The idea was to model a rectangular volume with a grating in the center that would output different orders of light where the output angles of each order are dependent on laser wavelength, crystal index of refraction, and wavelength of acoustics. I believe I can create a script that varies each of those parameters through the integrated programming functions. What I’m not sure about is how to go about modelling this. Does Zemax have any built in models for this or has anyone tried this before? I’m assuming sequential mode is the way to go, but if not, please enlighten me. Any help would be much appreciated. -Michael
Hi everyone,I want to do a Flye´s Eye simulation with a non-ideal array of orthogonal lenses.The ideal shape as it is provided as zemax object has 0 curvature between the lenses.What I want to simulate looks like this (concave curvatures between single elements - see document attached).Since I did not found a way to design such an object with my CAD program, I would like to know if it would be possible to create it with OS. Thanks in advance.Stefan
Hello everyone,I am trying to measure my model’s Field of View in sequential mode. My model involves reflective surfaces , absorbing surfaces and Transparent surfaces, the function of this model is to view surrounding. In Analyzing tab → biocular systems → field of view: I can not display any reasonable value. Can you help me out with this?
Dear Sir/Madam,I am getting the geometric error when I am running the Ray Trace Tool. Light is going from fiber (illuminating fiber) to Mirror, and after reflection form mirror it is again going back to same fiber(illuminating fiber), I think this is creating error while ray tracing, Is it? I want reflected light in receiving fiber only.I am attaching the screenshot for your reference. How to overcome this error, please help me out, or else Can I gnore this error?Thank you.
Hi all,I am wondering if it is possible to model the stacked holograms in which each hologram has its own construction wavelength and sensitive angles like the Figure 1(each color represents different holograms and their corresponding incident and diffracted light beam) shown below? I have tried to make one model in Zemax non-sequential mode(the file attached below), however, it doesn’t work as I expected. I am really appreciated for any help or comments! Thank you!--Kaden
I'm practicing optimization using a few operands.The lens performance deteriorates significantly after optimization than before optimization.I will attach the zemax file and PPT file.Please understand that this is an old zemax version. How can I make the optimization process go well?I don't know what my fault is.Please help. Thanks
Dear community,I’m working on a system that contains a simple SV lens and a human eye model (taken from Zemax library, with small changes).A co-worker wrote a code in Matlab with the exact same system and we wanted to compare the images sizes that was received on the retina.We’re receiving a huge difference (two orders difference) between the result from Zemax and the results from Matlab, and we suspect that something in the Zemax system is wrong, or the calculation in Zemax may be wrong. I’m attaching my Zemax system, hoping someone here could help me understand if I did something wrong. Also the value of the image size that we received from Matlab is: 3.58 x10^-1 µm both in X and Y direction Thank you
Hi Hui Chen ‘I do a tolerance run for an afocal optical system, I would like to know how much the centroid move or deviates from the center . I was thinking of to use merit function criteria with operand CENR: X & Y instead the footprint data. Thank you for your reference
Hi everyone, I am trying to design a dispersive system which requires that the image points of certain wavelengths at certain field positions coincide on a surface, i.e. are focussed on the same spot.To be more precise: If have 3 field positions (in the plane of dispersion) and 3 wavelengths. In the system, which is de facto a mirrored spectrometer, 400 nm at field 2, 550 nm at field 1 and 700 nm at field 3 must coincide on the image plane.How can I include this requirement in the optimization function?I couldn’t find any solutions here or optimization parameters in the help screen.
Hi,is there a way to specify the surface imperfections in the ISO drawing as per the visibility method (40-20 scratch-dig for example), instead of just the dimensional method (NxA, CN’xA’...)?The ISO 10110 standard has been updated (in 2017) to include both methods.I am using Zemax 20.3.1.Thanks,Audrey
Hello everyone, I bought Optical System Design Learning Plan , however I can not reach the course plan in my account. I followed the instructions as explained in the link https://opticsacademy.zemax.com/page/faq That still didn’t solve my issue. Have any of you come across anything similar to this? Any help is extremely welcomed.
Hi,I am new to straylight analysis in OpticStudio, and would like some recommendation on which module(s) on the “Illumination & Stray Light Learning Plan” to take:https://www.zemax.com/collections/illumination-stray-lightI will likely be doing ghost and straylight analysis on small refracting and catadrioptric objectives for Earth-observation cameras. I will also need to design baffling systems.I am pretty sure I won’t need the “Illumination systems: optimization and tolerancing” module but I am not sure if I would need all the other modules to fully understand the last one, “Stray light”, which will be definitely the most useful to me.Thanks for any comment on this.Alba
Hello everyone. I am interested in optimizing an optical system that contains a micro-lens array. I am aware of the user defined surface type and the "US_ARRAY.C" objects. I understand that this would help me build the optical system, but now I am interested in optimization. Since the MLA will generate multiple spots/wavefronts, how can I include this information into the Merit function?Also, in order to diagnose the performance of the system I would like to know the MTF for each lenslet. Is it possible to build an analysis plot that only considers rays from a specific region of the image?Thanks very much in advanced for any help.John.
