Hello ZEMAX I am designing in non-sequential mode. My ZEMAX version is 11 (very old) I designed three hexahedral lenses and there is air between the lenses. And there is a Source Point in LENS1. The Cone Angle of the Source Point is 180.0. From now on, I will explain the problem. When the light generated from the source point in LENS1 escapes, no refraction occurs on the LENS1 surface. However, when the light enters LENS2 or LENS3, refraction occurs. (If LENS1 is excluded, refraction occurs) If there is a point source in lens 2, no refraction occurs in LENS2 surface. On the other hand, refraction occurs on the surface except LENS2. Is the space with the source always considered air? I have attached the NSC 3D Layout. Thanks Suhwan Kim
I have a non-sequential component model with two configurations. The wavelength bands in the two configurations are different as is the aperture size. Everything else is otherwise the same. If I 'Ray Trace' with analysis rays, do both configurations get traced and, if so, is there a way to filter out one of the configuration's ray traces via the filter string?
I want to give a customer access to a Zemax model, while hiding our proprietary optimizations. I have previously used the Black Box feature to do this with no issues, with other clients and with similar models. The customer does not have access to Optics Studio 20, so I downgraded my installation to version 16 and created the black box. The file that Zemax generates to hold the black box gives the error 'Pupil Ray TIR' and will not update. The model only has reflective optics, so there is no refraction at all. I was able to successfully create the black box and open it in Optics Studio 20, but this will not work for the client. Are there any suggestions for solving this problem?
I am using Zemax for spectrograph Stray Light analysis, but I got some issues with the grating model. I used two objects (the front object is rectangular Volume, the rear one is Diffraction Grating). When I tried to find the strongest scatterings, one path is shown as the below figure. The light bumps several times within grating. It seems the reflection happens on the inside surfaces of grating, which is not reasonable in the real world. I am not sure the grating model is correct in NSC. Please give me some suggestions about this. Thanks.
Hello, I want to optimize my system by calculating the optical path length between to surfaces in non-sequential mode, similar to what PLEN does in sequential mode. Is there a way to do this? My goal in this is that the beam travels an exact distance before it hits an off-axis mirror. Thanks!
Here is the discussion space for the OpticsTalk: Peak Nano GRIN Optics, which was hosted by Dr. Rich Lepkowicz, Senior Vice President, and Dr. Guy Beadie, Director of Optical Technologies at Peak Nano Optics. In the talk, Rich and Guy presented a background on GRIN optics, reviewed the principles and capabilities of their layered gradient index (LGRIN) elements, and shared insights in applying LGRIN elements into existing optical designs, including considerations of the metrology and tolerancing of their LGRIN optics. Please find the slides attached to this post! Have questions or comments? Post them here to keep the conversation going!
Hello, SOME of our users are currently having issues checking out network licenses because they simply don't show up in the ZeMax License Manager, however it does for some clients. All clients are configured 100% the same in the Sentinel License Manager, and I've attached screenshots of a client who can access the licenses (ava-cmurphy) and a client who can't (ava-dwebberd). Additionally, all clients are using the exact same firewall and have all the same Group Policies. I've spent hours troubleshooting this today and I'm out of ideas as it's working for some folks and not for others even though they're all configured the same. Here are some of the troubleshooting steps I've taken: Tried using various names/IPs for the server (FQDN, local IP, hostname) Confirmed all clients can ping server whether they can retrieve license or not Uninstalled and re-installed the License Manager on the server Compared configurations on server, broken client, a
Hi support team, Is it possible in OpticsStudio 21.1 to set the structure of Data Lens Layout? The problem is that the order and the width of the columns change every time I open a new file. i.e is it possible to set the order of the columns and their width in the layout, permanent? Thank you for your help, Tali M.
Here we will introduce some FAQs about Relative Illumination in 4 topcis:* How is Relative Illumination calculated* Considering Fresnel loss* Situations that Relative Illumination cannot calculate* Relative Illumination in systems with FOV > 90 degrees* Cosine fourth Law It's suggested to see also this forum post:
I have a question about the correct way to simulate relative illumination in an imaging lens. The lens is designed to work with apertures between the lens elements which introduce some vignetting towards the edge of the field. The apertures are defined explicitly as 'Circular Apertures' at each surface in addition to a user defined 'Semi-Diameter' at the same value. The lens semi-diameters are defined in the same way using surface 'Circular Apertures' in addition to setting the same aperture semi-diameter as user-defined in the 'Semi-Diameter' column. Think of a kind of mobile phone lens -- the basic structure is similar as is the maximum field angle of about +/-37deg. The company that does manufacturing claims that for the proper calculation of RI it is necessary to set vignetting factors (and not to set 'Remove Vignetting Factors' in the relative illumination settings) and to use polarization. In my opinion if I have defined at all surfaces surface apertures then I need not use vigne
I have a question. The lens of (A) is BK7. The lens of (B) is SF3. I designed the (B) lens inside the (A) lens. That is my mistake. At this time, which of the (A) and (B) lenses affects the light rays? (I am curious which lens affects the refraction of light rays.) I have attached the image.
I am an educator. I have a ZEMAX optic studio academic licence. I reinstalled my pc and when I try to install the software again, I get a license error. My license is used and I can't activate it again. Transfer code had to be created for the license, but I didn't know that. What do I have to do now? How can ı create a transfer code for my licence? The Best Regards...
I am using non-sequential mode. I want to do surface treatment of various shapes. I will attach an image. 1. Can only one surface be set for diffuse reflection? 2. Is it possible to treat only the center part of the surface as a diffuse reflection surface as shown in Figure (4)?
Hello, I want to tilt the last part of my system, but I want to tilt the image plane with it. For example, I hav 3 lenses and want to tilt the last two, with the image plane having the same tilt as the last two elements (see image). Is this possible? (I am working in sequential mode.) Or is there another way to solve the problem I have? L1 is a collimator, sending collimated light to L2 and L3, and I want to see the effect of sending collimated light to L2 & L3 under different angles. I have done it already using different fields, leaving L1 out and using obj distance infinity, but I want to know if there is a way if I can do it with L1 in the setup.
I want to know about magnifications of each lens groups in entire optical system. Especially, I wonder whether there are optimization operands about magnifications of each lens groups (defined surface to surface like operands EFLX, EFLY), or how to calculate the each magnifications of lens groups in entire optical system. Sincerely
Hi I want to model a Gaussian beam source in SQ mode. The laser specs are, - wavelength: 532 nm - 2theta: 0.7 mrad (FW)(1/e^2) - 2w0: 1 mm (FW)(1/e^2) - w0 position: laser head output position - M2 < 1.1 In this situation, the beam waist cannot be a point source. Then, what should I set(aperture type, object position, etc.. ) for the modeling in the SQ mode? Thanks in advance
Hi support team I tried to simulate 'How to model holograms in OpticStudio' as described in: https://my.zemax.com/en-US/Knowledge-Base/kb-article/?ka=KA-01795. The article talks about two files: construction_1.zmx & construction_2.zmx needed in order to simulate OFH.zmx file. However, I can't find these 2 files in the zar. files you attached to the article: So, where can I find them? Are they needed? Thanks, Tali M.
I have measured the surface deviations of a 16mm diameter lens with a Zygo running on MetroPro and have exported a 37 term Zernike Fringe Sag data table. When I enter the Zernike Fringe Sag coefficients directly into OpticStudio the magnitude of the resulting transmitted wavefront error is appropriate to the expectation based on the surface error but the Normalization Radius was left defaulted to 100 in OpticStudio and was not set to match any corresponding radius value in MetroPro. If the Norm. Radius is changed the resulting wavefront changes but not in any way that makes sense with regards to the Zygo measurements or expectation. Is there a method to set the Normalization Radius in OpticStudio such that Zernike Fringe Sag data imported from MetroPro can be correctly used to model an as-built lens? Could the MetroPro output also assume a Normalization Radius of 100?
Hello, I have a rectanular field type and need to determine focus position of each field on the microdisplay. For example, if I take microdisplay wth 15,5mm*8,7mm so the field [19;7] need to be focused in position of the microdisplay wih coordinates [7,75mm; 4,35mm]. What operand should I use to determine position of the field focus on the microdisplay (for each field)? Thank you in advance!
Hi I am trying to work out the irradiance at different distances from a given light source. I was supplied with actual values from empirical testing, and I thought OpticStudio would corroborate that. However, I found that I got very different answers. I have since found out that the results that the Ray Trace gives (peak irradiance for each detector) can give greatly different results depending on the # X Pixels and # Y Pixels that I set for the detectors, and also for the number of analysis rays for the source. All I want is an accurate value for the peak irradiance at certain distances from a source. Is there an easy way of setting this up? Thanks in advance Jo Ling
Hello, I ould be really thankful for clarification how to achieve a paraxial Magnification. So I have system of two paraxial lenses with focuses 100 and 200. And I need to determince distance beween lenses and distances from lenses to the object and image. The magnification is M=-1.1x and total length of the system is 800mm. So what I did. I definedthe obeject height 1mm in Fields and in merit function determined operand REAY with Py=1 and target=-1.1 to receive Magnification -1.1. But afer the optimization Paraxial Magnification less or higher than desired -1.1x. So how is it possible to achieve the exact magnification M=-1.1x? Thank you in advance!
