What kind of data being included in 22.2 Speos Exporter OPTDistortion file? 

I am modeling some CPC’s in NSC. I know that they are not 100% reflective and I want to assign a coating to the inside surfaces. But in OS, NSC, there is no way to apply a coating to a surface. Why is this? I can think of many reasons I would want a surface with a coating. A simple cubed beam splitter is one example. Define a cube of glass and then put a 45 degree surface inside with a 50/50 coating. Or, make CPC’s objects rather than surfaces. Anyone have any thoughts to a workaround?Thanks,Paul

The article demonstrating how to use an OFH correct for aberrations introduces these operands, but neglects to tell you where they come from or how they're used. When you select Add Hologram Variables, you get an entry for every item in the accompanying 2 files that has been made a variable. Note the entry File # that tells you which hologram file the variable is from: The list will include the same # of variables from both models. If the number of variables is not the same, the excess will be populated with 0s and unchangeable. In the following example, construction file _1 has one more variable than construction file _1, and so variable #3 is a 0 with no V indicator, and modifying it does nothing to the construction model.  Frustratingly, they don't tell you where the Variable # comes from. It is located in the respective construction files under Prescription Data. Scroll to SOLVE AND VARIABLE DATA. The variables are listed in order and s

I got New License for Zemax OpticsViewer.I wont adding new Enduser to it product. So, I wont this user to New Colleague.But at https://www.zemax.com/pages/profile, I can not Add Colleague. I write new colleague profile and click “Add Colleague” button, but not progress so far.

One of the big short comings of Zemax display window is that you can’t display Isolux lines (or any other contour Iso line such as Candela).  IsoLux lines are used in a variety of different industries from Automotive to Street Lighting to show areas meeting a given illumination level but for some reason Zemax think they are either not needed or too difficult to implement.  At the moment I have a display window that in False Colour just looks like it is 90% yellow/green and I need to show my customer the area that will have greater than his specified minimum lux level.  Can anyone recommend a free (or cheap) graphics package that can take the text output from the display window and show IsoLux lines?Thanks,Andrew

Dear community,there are already several questions about that topic and also there are useful support here:https://support.zemax.com/hc/en-us/articles/1500005486701-How-to-simulate-high-resolution-images  However, I am still having some doubts about the following questions.Let consider that I am in the condition in which I have a 1:1 magnification lens, and I am setting the Field Type as Object height at 5 mm as “Max Field Y” and I have set the distribution as “Uniform Y Fields”.  So I am in this condition: In that condition the Full Height of my Object would be 2*5(mm) = 10 (mm). Now I want to simulate, for example, how will appear my image in my system. To make my simulation more real, I want consider my camera sensor that is a 2048 x 2048 pixels with pixel size of 6.5 microns. I want to further optimize my simulation, therefore I am gonna to create a new image with the dimension of the pixels that matches the dimension of the pixel of the sensor.  created imagepixel dimensions of th

Hello! I want to import the data of a rotationally symmetric contact lens to Zemax OpticStudio, and I thought about ding it with the grid sag surface. Does anyone know if it is possible to create a circular grid surface in the grid sag surface type, instead of the square one given by default? It would be much easier for meThank you very much,Alicia

Hi there, I am pretty new on Zemax and I am trying to understand how to optimize some values. I have some issues on that.I am using a lens from the lens catalogs and I want to minimize the Spot radius on the image plane by moving the object in Z. Which is the best merit function I could use to do that? I put the operand variable on the the thickness of the object and I am not sure of the best suitable merit function for that. Thanks in advance for your support. Gianluca

Hi,I noticed that the exit pupil position for an off-axis system with mirrors (eg. a TMA) seems to be off when the STOP is at the curved surface of one of the mirrors and ray aiming is turned on. I understand this to be somehow expected since the pupil solve in the LDE and the EXPP operand work in paraxial approximation, and such system is definitely far from paraxial.Is there another way to approximate the exit pupil position when ray aiming is on? Thanks,Paolo

Hello all,I have a simple system of a source and an object (CAD object checked with “object is a detector”). The CAD object has a coating defined with 80 % reflectance and 20 % absorbtance.I´m trying to get the absorbed energy via ZPL macro with the operand NSDD. However, with the macro shown below, I always get the fully incident energy and not only the absorbed one. temp=NSDD(1,0,0,0)NSTR 1,0,1,1,1,1,15detector1= NSDD(1,2,0,4)PRINT "Absorbed energy:    ",detector1 In the help file (Non-sequential Ray Tracing and Detector Operands) it says:For Object Is A Detector: There are two additional options for data. Data is 4 for absorbed flux and 5 for absorbed flux/area.What am I doing wrong? GreetingsJulian

Dear all,I not clear about “sampling importance” about scatter to method menu. The size is about the size of radious of the sphere that would be placed in target object but the limit ? why “1” is the default value? 1 stereoradian? The difference between power total with or without sampling importance is almost the same. I understood that importante sampling has to do with the scatter effect in the surface. thank you in advanced for your comments

Dear, I am using tolerancing tool and sensitivity analysis base of the merit function. My merit function would be working distance (distance between last surface and image surface). Could you advise me with proper operand in merit function.   Thank you

 RT，I have design a pancake optical system, now, i want to make a tolerance analysys for the system which have the pick up for lens, and the Zemax have a better method for such a system?Thank You!    @Yuan Chen[Mod edit: Moved to appropriate forum (Got a Question?)] 

Hello. I'm trying to simulate a simple imaging system in non sequential mode. My setup consists in a source radial, a 4f telescope, a 1200 lines/mm diffraction grating and a detector color. I would like to insert a reflective grating, but I can't seem to find a way to do it. I was only able to insert a transmission grating by choosing a Diffraction Grating from the Object Type menu. I tried changing the parameters in the Object Properties, varying the 'Diffraction' settings: I selected 'Split by table below', in the 'split' section and set 'Start order:0 , Stop Order:1'. Then, on the 'Reflect' section, I set 0.5 for both orders and left 0 in the 'Transmit' section. I'm going to post a snapshot of this menu. Anyway, nothing of this worked, so instead of 'Split by table below', I chose 'Split by DLL function'. In the DLL section I selected the diff_samp_1.DLL , but for any parameter I insert, the grating still keeps working in transmissive mode.

I’d like to change a general spherical mirror into a off-axis parabolic mirror to avoid astigmatism. In order to do this, I input ‘-1’ as conic 1 parameter as you can see following image.But It doesn’t work at all….  Could you help what did I missed?  

Could anyone share a successful specification sheet example for a Mangin mirror to go out for quote?  I have the toleranced radii and center thickness, edged diameter and clear apertures all defined, calling out wedge across clear aperture to be less than 25µm, polish quality, AR coating on the refractive surface, etc. all complete.  What I don’t know is how best to specify the reflective surface.  I know the desired reflectivity, which will likely either require aluminum or silver, but I’m not familiar with how to specify the protective coat(s) that is/are applied on top of the reflective coating.  Is flat black epoxy paint OK, or can it oxidize the coating and cause delamination?  Does an intermediary non-oxidizing, adherent coating need to be applied over the reflective metal before painting flat black?  Thanks for any advice.  Mike

I’m currently working on a program that is working over a waveband where Zemax won’t or can’t calculate an Abbe tolerance.  The tolerance data editor when using the wizard doesn’t even include the TABB tolerance operands and if inputted manually are ignored in the sensitivity analysis.  Since this is the case, is there a way to check the tolerance sensitivity of the design to variations in index with wavelength?   

Micro lens array (MLA) is a common optical components for illumination system. OpticStudio provides two object types to define MLA in NSC mode, which are “Array” object and “Lenslet Array” object. In the page of “Lenslet Array” in Help file, we can see the following description.“The array aspects of this object are provided for back compatibility with older versions of OpticStudio. A more efficient method that ray-traces more quickly is to make a single lenslet and then create an array using the Array Object - see “Array” for details. “However, at least when the number of lenslet is large, for instance 70 x 70 = 4900 cells, Array object is not always the best choise.The table shows the elapsed time comparison in updating 3D Layout and NSC ray tracing with the NSC mode system having 70 x 70 MLA. MLA is defined by Lenslet Array or Array.  Lenslet Array Array Updating 3D rayout 22 sec 2 sec (faster) NSC ray tracing (5E+5 rays) 1.8 min (faster) 9.1 min  Lenslet Array is 5 ti

Hi, everyone,I’m a student want to produce a line shape illumination and a newbie in Zemax.I use a Xenon lamp with narrow rectangular light source which has NA 0.57, hoping that by two orthogonal cylindrical lenses to concentrate the light to improve the light efficiency first, and then pass through a slit. Later pass through another two orthogonal cylindrical lenses and make the light collimated. However, this is not collimated enough for my f-theta lens. The dimensions are in attached files in detail, hoping who can give me suggestions of my illumination design, thank you very much! my goals:wavelength range: 450-650 umoutput line length: 8.8 mm in diffraction limitvariables: distance between the cylindrical lens or other suggestions for lens substitution is welcome. 

Hello,I am attempting to model a system that has 400 nm light emitting from a fiber, going through a lens, reaching a flat mirror, then retroreflecting back to the fiber. The scale of the system is on the order of a few mm. I am determining whether a GRIN lens or an asphere would work to have a small footprint back at the fiber while having minimal spherical aberration. I am currently modeling the system in sequential mode to keep the model as straightforward as possible until more complexity is required. However, when I am attempting to determine the aberration and footprint properties of the GRIN lens, I get the error message that double pass does not work for gradient surfaces like the GRIN lens I am testing. Is there a work-around to get the GRIN lens modeled properly with a double pass system? I can provide more information/context if needed. I would greatly appreciate any assistance. 

Hello all, I have a micro optical system of source - material (flat lens + coating) - detector for which some optical characterization is need to be done.I am using OLED display having each pixel of size 50x50 um, and I need to create an array of such single pixels with various wavelength and position in a plane of the light source to mimic OLED display.for material, I need to design a flat lens of 6 um having a patterned coating (varied thickness or varied refractive index) of  100 nm. the system is transparent enough to have a transmission function.and I am using a CMOS sensor to record the responses of each illumination of LED sources in OLED display. and each of this is separated by a distance of 1 - 2 mmnow for the challenge, I need to create an exact or close model to this system to know and play with different parameters suggested. I also want to know dispersion and scattering involved in the system. I know for sure we can analyze required parameters on Zemax (either in sequenti

I developed a lens simulation that generates a zernike standard coefficient of up to 37 terms. I use MATLAB to obtain the zenike coefficient for comparison with the real system. So, should I multiply every coeffcient with wavelegth during the extraction process, or should I just extract since it is? Because, Zemax simulation has Concave lens geometry. and when I extract zernike coeffcient and multiply with wavelengths, it become very higher values.[Mod edit: Moved to appropriate forum (Got a question?)]

Hello everyone, in a backlight project of an LCD screen with backlit lighting I would like to use the optimization function by assigning a variable to the x and y positions of each source (6 sources) and I would like to define the max variation range for each variable.It's possible? Thanks to all.

I still haven’t seen evidence of Zemax providing matrix instead of vector configuration mappings.  In other words, if I have five temperatures and five different radii, for example, I still have to have a vector of 25 consecutive configurations rather than having a 2D 5x5 matrix of configurations.  What is the status on providing configuration matrices?Thanks, Mike
