Python Multithreading with POP

I’m working on running multiple POP simulations and they each take about 30 minutes. I’m debating trying out the python package “threading” to try and run multiple runs at the same time in order to save some computing time. Are there going to be any limitations on the Zemax side of this equation?

Help with POP Python

Hello,I am having some difficulty finding answers on this elsewhere online and have not found any helpful forum posts on this either so here I am. I am trying to communicate with the POP with the python ZOSAPI with the program in interactive mode. Currently I have tried this little code snippit to set the surface desired to 2 and pull the irradiance with not much luck. Python more or less yells at me with an error saying “IAS_ object has no attribute ‘EndSurface’ I am not having the best of luck finding a solution to this problem in the help document. Please Help! :)FYI: See code snippit below # initialize analysis toolsTheAnalyses = TheSystem.AnalysesPOP = TheAnalyses.New_Analysis(ZOSAPI.Analysis.AnalysisIDM.PhysicalOpticsPropagation)POP_set = POP.GetSettings()POP_set.DataType = ZOSAPI.Analysis.PhysicalOptics.POPDataTypes.IrradiancePOP_set.EndSurface.SetSurfaceNumber(2)POP.ApplyAndWaitForCompletion()POP_result = POP.GetResults()Irr = float(POP_result.DataGrids(1).Values) Cheers,Armand

Remove unused glass from lens

In the system represented in the attached figure, the second lens has a significant ammount of volume which is never transversed by any ray. An improved design would make the second lens shorter, by a vertical cut that would remove the two circled regions in the figure.How can I implement such structure by tuning the lens parameters?I´ve tried playing with the diameter and mechanical diameter, without a result. Kind regards,

Geometric image analysis ZPL API incomplete

Hello! A feature request -- could you please complete the ZPL API for geometric image analysis? It would be handy to be able to modify parameters available in the GUI that aren’t included in the API yet like the “use polarization” check box & the reference dropdown menu. Thanks!Liz

Structural constraints for the off-axis three-mirror system

Hi everyone, I have a question for you.I want to design an off-axis three-mirror imaging system (in sequential mode) but I don't understand how to control the five distances pictured in the image below.I'm looking for a way to avoid light obscuration and prevent surface interference when optimizing.Until now, I tried to control the distances using the global vertex coordinates MFE operands without success. Any suggestion would be really appreciated.Thank you.

Fiber coupling and wavelength

Hi,I’m trying to investigate the effect of different parameters on fiber coupling (receiving fiber only), such as focal length of the injection lens, wavefront aberrations, fiber NA, etc…The system is a 19mm parallel beam, a paraxial lens, and a single mode fiber at the focal plane.It seems that the wavelength value has no effect on the fiber coupling efficiency (FICL operand). This seems not physical to me…Any idea?Thanks

Circular polarization transformed into linear polarization

Hello everyoneWhen I input horizontally polarized light (in the x-direction) into a 1/4-wave plate oriented at a 135-degree angle relative to the x-axis, it should generate clockwise circularly polarized light. Subsequently, after reflecting this light using a mirror, it should become counterclockwise circularly polarized. When this reflected light encounters a 1/4-wave plate, theoretically, it should result in vertically polarized light (in the y-direction). However, what I observed in the polarization pupil map is horizontally polarized light in the x-direction. Have I overlooked something, or have I misunderstood a certain definition?Thanksshun

Why we do not need a core diameter in calculating coupling efficiencies for a single mode fiber?

Hi all,In oder to calculate coupling efficiencies for a single mode fiber (Anlysis>Fiber Coupling>Single Mode Coupling) in the sequential mode, required specifications for fibers are numerical apertures and relative positions/angles to light sources. To my knowledge, a calculation of the fiber coupling requires a core radius and/or mode field diameter (MFD) as well as numerical apertures. I was wondering if we could get the coupling efficiency even without knowing the core radius or MFD values of single mode fibers in OpticStudio. Please correct me if I’m wrong.Your help would be highly appreciated.Thanks.

Reverse a HUD system

This post provides a potentially working method for reversing an off-axial sysetm such like a HUD. It may not work with all systems, but have been proved to be useful for some systems.Turn off RA. Clear all fields. This is becuase RA will throw erorrs during the following tweaking. And the field data is unlikely to be unchnaged so let's just remove it and re-add them later. If the number of mirrors is odd, add one more mirror after object, using the Add Mirror Tool. Add a dummy surface after object and before image. Select all surface and reverse. After reversing it, multiply all decenter/tilt by -1 and set Order flag to opposite. Remember to adjust image and object distance. and turn on the RA again. You can remove the dummy mirror if you add it at step 2.In the attached video, we showed an example of using this process with the following example in the KBA. Note in the video, I forgot to do the final step to turn on the Ray Aiming.https://support.zemax.com/hc/en-us/articles/150000557

Zoom System

Hi everyone,I am in the process of designing a continuous zoom system with magnifications ranging from 3x to 5x. However, I have encountered some challenges in meeting the desired specifications.Here are the basic requirements for the system:Working Distance: 500mm Field of View (FOV): 80 - 100 mm Total Optical Tube Length Requirement (TOTR): 50-60 mm (for the lens system) Objective Diameter: 18 mm Eyepiece Diameter: 12 mmI have initiated the design, but I'm facing issues such as achieving the required FOV and encountering image blurring.I have attached my initial design for your reference.I would greatly appreciate any guidance, suggestions, or insights on how to proceed with this design. Your expertise and advice will be invaluable in helping me overcome these challenges and achieve the desired performance for the continuous zoom system. Thanks.

Very Slow Parameter Setting in ZOS-API

I am writing a program where I need to make several changes to values in the Lens Data Editor (e.g. parameters of a coordinate break surface) and evaluate merit function operands after each set of changes. The problem is this is extremely slow, to the point that setting the parameters dominates runtime far beyond the time spent raytracing. For example, this function averages about 1 second per call:def set_offset(oss, surface_number, x, y, about_x, about_y): oss.LDE.GetSurfaceAt(surface_number).SurfaceData.Decenter_X = x oss.LDE.GetSurfaceAt(surface_number).SurfaceData.Decenter_Y = y oss.LDE.GetSurfaceAt(surface_number).SurfaceData.TiltAbout_X = about_x oss.LDE.GetSurfaceAt(surface_number).SurfaceData.TiltAbout_Y = about_y I’m sure there are some minor optimizations I can make, but at its core, setting a single variable in memory shouldn’t take anywhere near 0.25 seconds.Am I doing something wildly wrong, or is there a far more efficient way to modify LDE entries? Is ther

Phase Mask

Is there a way to import an image into OpticStudio and have that incorporated into the light path? For example, I’d like to import an PNG file (Example: a white background with a black rectangular outline) and have light passing through it and observe the wavefront distortions that result. How can I do this?

Listing the Q-bfs Polynomials

OpticStudio supports Q-type aspheres. Type 0 indicates Qbfs polynomials, and Type 1 indicates Qcon polynomials. The functional forms of the Q-type polynomials are fairly complex due to the requirement that the polynomials be orthonormal for a circular aperture. Occasionally, it is convenient to know the functional form of the polynomials for testing and comparison purposes. Below, we list the first 10 Qbfs polynomials, and also share how to calculate them in the Mathematica file GenerateQbfsPolynomials.nb. The .nb files for Mathematica can be used by downloading the free Wolfram Player: https://www.wolfram.com/player/.Important equations for the Q-bfs polynomialsThe equations used below come from Shape specification for axially symmetric optical surfaces, G.W. Forbes, Optics Express 5218, Vol. 15, No. 8, 16 Apr 2007. Forbes watned to find a function whose slopes are orthogonal. So the slope equations must obey:where u is the radial coordinate in the aperture of an optical surface

How to model the oblique incidence onto polarization optics like Jones Matrix in Zemax?

Hi all, For Jones Matrix in Zemax, according to the definition, I think it is only designed for normal incidence. However, what if I want to model the oblique incidence onto the half-wave plate (HWP) which I use Jones Matrix in Zemax non-sequential mode? I tried it and found the energy is not conserved. Does that mean we have to design some new HWP by ourself or is there any other avaiable surface can be modeled as HWP for oblique incidence in Zemax? Kaden
