Export ray trace in non sequential mode

Good afternoon, I have some questions regarding the export of Zemax non-sequential mode ray trace into Catia. To trace rays, I use Analyse>Ray Trace with 10millions layout rays. At the end, I have a .zrd file. Is it possible to directly convert this file into a file readable by Catia ? Or is it possible to export directly the design with the layout into a .stp file or again a file readalbe by Catia ? Do not hesitate if you have any questions, Thank you in advance for your reply, Best regards, Nicolas Letort

How to optimize Binary 1 phase to be like a prism function?

I'd like to set a field angle in object space,e.g., 10 deg.  After Binary 1, the rays would be 0 deg.  What merit function can we apply for this work? Best wishes,  CM tsai

Source TE Polarization

Hello together, how can I model a TE polarized Source Diode? Short to the background: I want to hit an object with the light beam and than I change the angle of incident. So normally you should see the Brewster angle, don't you? My problem is, that I can not see the Brewster angle. Thank you very much for your help. Best Christian

Analysis of plastic material according to temperature (within the range of -40 to 80 degrees)

Hi, i have some questions.   From what I understand, it is possible to analyze the absolute refractive index as a function of temperature if a thermal dispersion coefficient is provided. For plastic materials and in the range of -40 to 80 degrees, is the simulation accurate when all of the thermal dispersion coefficient is provided ? And for some plastic materials, it is confirmed that only one thermal dispersion coefficient(D0) is provided. I wonder if it would be accurate to simulate with this material within the same temperature range as above.   Thanks for reading my Post.

Aborting a Computation

Hello,  I have an issue where if I open up a file, Zemax will run all the analysis that I previously had open. Usually, this is not an issue, but sometimes I might have something time intensive open, such as Physical Optics Propagators. I know that I can set auto-analysis off, but If I open I file up, where this is not already set, all I can do it wait.  Is there a hot key that aborts all current analysis ? Hitting Terminate on it does not work in the case of just opening up the program.  Thanks

Fixing Bugs - Saving Plots/Files with Period Characters in Them

Probably 1.5 years ago I submitted a bug report for Zemax to fix a bug where the filename would be cutoff at the first dot/period in the filename. For example, saving a plot as 'def=1.35_xxx.png' will only save a file as 'def=1.png' Come on, it's not that hard to fix!

optimization in nonsequential mode

I want to design a collimating optic and I have a model of my extended source in nonsequential mode. When I optimize, the lens gets unreasonably thick. Is there a way to put a limit on this thickness in the nonsequential mode? I am familiar with how to do it in sequential mode, but I don't see the same features in the Optimization Wizard in nonsequential mode. Thanks!

Layingout zoom lens

Hello everyone, I am trying to warm myself up on trying to layout zoom lens. In my practice example I am trying to make a number of lens to have 3 zoom locations.  For the beginning I started with 7 lenses, I am taking effort on making the lens layout applicable for 3 configurations having 3 different focal distances for zooming purpose. Although my initial configuration come out pretty well -not hard to have an initial configuration- when it is the turn to determine the rest of the other zoom configurations that might become painstaking. I make use of Multi-Configuration Editor for 3 different configurations. I haven't got a confident clear workflow on making zoom configurations yet. Any suggestions are welcome. Best Wishes

Filter in NSQ

Hi, how do I creat in NSQ a RG squer Filter? I created a proper coating (T depends on wavelenght). Like in 'How to define metal materials in OpticStudio'. And I stuck with creating a simple squer volume with customed size where I can put the coating on. Thank you for help in advance.

Feature Request: don't save ZOF/SAB extension in ZMX models for CAD files

ZOF and SAB files are used to speed up model loading when using large CAD (e.g. STEP) files. According to the user manual, the original STEP files should be shared with the model, and ZOS will automatically pick up the ZOF/SAB file, if present, to speed up loading. Makes sense. However, in the ZMX file, the ZOF / SAB file is referenced. For ZOF files, it doesn't hurt: if ZOF file is missing, ZOS will still use the STEP file. However, if the newer SAB file is used, and my colleague is not using one of the recent ZOS releases (common in corporate environment), their ZOS doesn't know what to do with the SAB extension and doesn't understand that it should read the STEP file instead. Since saving the filename in ZMX with this extension shouldn't, by design, have any impact on the loading speed, the proposal is to use the original file extension (STP in this case) always. It is a future-proof solution. Am I correct in this thinking, and can we have such feature please? P

Non-sequential Modelling of an Acousto-Optic Modulator (AOM)

Hello Zemax-Community, I want to model an Acousto-Optic Modulator (AOM) in the non-sequential mode as precisely as possible with OpticStudio. I want to simulate multiple diffraction orders as well as the effects of the refractive index of the AOM, the parallity of input and output surface and thermal lensing effects. Looking through the non-sequential objects in OpticStudio the Rectangular Volume Grating was the closest match I found. The Rectangular Volume Grating adds a linear diffraction grating on four faces of the object: the top, bottom, left, and right faces. This leads, however, to a simulation error since it is typically assumed that the 'effective grating' in the AOM is located in the center of the AOM. Are there better or other ways to model an AOM in OpticStudio? Has anyone solved this problem by writing a user-defined DLL?   Steffen Erhard

How to set up the coating

Hi Zemax users I want to set up the coating. I know the refractive index, thickness, reflectivity, and wavelength of the coating material. I wrote the following in the coating file. But I couldn't record the reflectance when using the COAT command. And, when using the IDEAL command, the thickness could not be set. How do I set up a coating material with 0.1mm thickness, 98% reflectivity, and 1.64 refractive index ---------------------------------- MATE BASO1 0.42 1.64 0 COAT BASO4 BASO1 .1 ! IDEAL BaSO4 0.00 0.93 -----------------------------------   NAME Thickness refractive index reflectivity WAVELENGTH BASO4 0.1 1.64 98% 0.42   Suhwan Kim

Surface roughness tolerance analysis

Hello! I am trying to performe a tolerance analysis in a secuential systems with some mirrors. I want to analyse the impact of the surface roughness on it but I don´t know how to relate the scrach/dig parameter with the parameters that appear on the tolerance wizard or with the tolerance operands. Do you know how this can be done? Best regards, Jose

Maximum Number of NSC Editor objects

Is there a maximum number of objects that can be added to the Non-Sequential Component Editor? I'm looking to programatically add an extremely large number of objects to the editor (>2500) using ZOS-API. The vast majority of these objects (~2100) will be arrays referencing another object or objects, and as such will not take up as much memory. Thanks!

TOLR KA-01370

Hi Zemax team,      I've been studying the tolerancing, and I read the KA-01370 written by Mark, which is very helpful. I have a question about this paper : in the merit function editor of the Doublet_Starting_Point_with_TOLR.zmx, there are no TRAC operands  ,whereas there is 'the default merit fuction:RMS spot radius centroid GQ 4 rings  6 arms'. can anybody help me with that?

surface not showing on shaded model but does show on layout view

Hello, I am trying to model an on-axis reflector telescope with two mirrors.  The second mirror surface shows in the 2D layout window but does not show in the shaded model.  Why the discrepency and how do I fix it?  I am not sure if the reason why the second surface does not show is because after the second surface, the rays go through the first surface (but I haven't figured out how to make a hole in it, yet, so realistically nothing would go through, yet).

Is there a way to plot symmetrical rays in non-sequential mode?

I want to make a presentation and need to include some NSC 3D layout plots from non-sequential mode. I know the rays displayed are randomly chosen, but is there a way to choose symmetrical rays, so as to have a similar effect as the plots produced in sequential mode?   Thank you.

Tolerance analysys in multiconf

Dear All, Sorry for this potential stupid question, I'm relatively a new optics studio user. I have an optical system with several configurations (several channels, to optimize pupil and image). I would like to perform a tolerance analysis and need to implement in the process a compensator to keep the collimation of my first optics. What is the easiest way for that ? - I though to create a new configuration and implement a paraxial lens and use the object frontal distance as a compensator. Problem: I didn't see how to change the surface type in the multi config area to implement a paraxial lens. - is it better to use a tolerancing script using the CMCO operand ? Other point, if I want to make a sequentlial analysis reprodcing my alignment procedure, is the best way to use the ZOS-API function for that ? Thank a lot in advance for your help

Silicon Window

Hello, I'm implementing a SWIR sensor package in an optical design. The latter is composed of the sensor and a Silicon entrance window. I'm looking using the Silicon material from the Infrared.AGF material file, the problem is that an error message is returned: the material is valid from 1.36 micron, while my design considers wavelengths down to 0.9 micron. What would be the best workaround for this? (since the material is not defined over the complete spectral range, optimization, and analysis wont work properly) Thanks much for your feedback
