Diffractive macro DOESAG.zpl is not available

Hi,I am unable to find DOESAG.zpl macro for getting the sag values for the diffractive aspheric surface. Earlier it was available in the knowledge base but now that is also not there. Can I get this macro as it is very useful to view the steps of diffractive surface and surface sag dataRegardsJ Himavanth kumar

IMAE runs slow

I’m changing four different parameters to find the highest efficency in an optical system.For this I have build a four layer loop that runs the comand IMAE and do some calculations using the returned value and the pramaters. Hovever zemax doesn’t seem to use the full processor capacity only about 7%.If I instead use the comand IMA to run the geometric image analyze the processor runs at full speed and the command runs more than 10x faster. Hovever I cant find any way to read out the data “Total flux”

Export detector data as text of a CAD Part as detector

I have defined a CAD part as a detector in NSC. In the text tab of the detector viewer I am able to see the Irradiance and the position (XYZ) of each pixel. I want to export this text file with a macro in ZPL. When I do this, I get a .txt-file but always with ‘Detector Viewer Summary’ and not with ‘Detector Viewer Listing’ data inside. I have tried to select the correct detector with ‘MODIFYSETTINGS’, ‘DVW_DETECTOR’ but it looks like, I cannot select the correct object. How can I export the correct text file with ZPL?

DLL (Surface Scatter) Non-Sequential Lambertian Depolarizer

This Surface Scatter DLL models a Lambertian scattering and contains a depolarization fraction parameter to depolarize part of the scattered rays. That DLL is a good example to demonstrate how to control the electric field and how to implement importance sampling. The code is based on "{Zemax}\DLL\SurfaceScatter\Lambertian.DLL".

MilothMonochrome

Hi, I used Rust to build a very simple DLL, inspired by the examples in C and C++ provided with Zemax. The source code can be found here. I compiled it from Windows and a Unix machine with cross compiling. Both versions were as fast as the C alternative I wrote. The compilation method is pretty straightforward and documented in the repo README.It was quite easy to implement similar workflows and structures for some of the other types of DLLs used in Zemax.Yet, I would like to do the same with the 2D version of the diffraction grating. I could only find mentions to the 1D grating in the Zemax docs. The provided code sample covers only a portion of the elements of the pointer and not all of them are fully documented. Does anyone have that piece of information?

User-defined Operand: Modulo operator

Hi all, I’m not going to create a repository for this, but if you quickly need a modulo operator in your Merit Function, there you have it. Hx and Hy are the operand numbers (integer) that will be used as the numerator and denominator respectively.The relevant part of the code is self-explanatory (hopefully):int numerator = (int)TheApplication.OperandArgument1;int denominator = (int)TheApplication.OperandArgument2;...double numerator_value = TheSystem.MFE.GetOperandAt(numerator).Value;double denominator_value = TheSystem.MFE.GetOperandAt(denominator).Value;operandResults[0] = numerator_value % denominator_value;To install, download the ZIP file, extract it, and move UDOC12.exe to yourDocuments/Zemax/ZOS-API/Operandsfolder. Then, in the MFE you can do:The rest of the division of 5.00 by 2.00 is 1.00.In case you are wondering why I made this. I needed to have a linear polarization without caring about the orientation. I noticed that using CODA with data=110 (phase difference), some linea

ZOSPy run FFT MTF

Hello,A comment on ZOSPy. I did already spent countless hours on my own python wrapper and I am very happy to see a team of skilled programmers working on that. Just getting rid of tons of boilerplate code is worth the effort!Getting connected to Zemax from my jupyter-lab to zemax as “Interactive Extension” works with ZOSPy or with the pasting several lines of boilerplate and directly acessing ZOS-API via pythonnet 3.x.Via ZOSPy I can add lenses, changes become visible in zemax. So I assume there is no general problem with library loading, connecting, etc..However, I cannot figure how to run a FFT MTF using ZOSPy. With the bare pythonnet this looks like this (Boilerplat-part from example 04 skipped)# Create analysisTheAnalyses = TheSystem.AnalysesnewWin = TheAnalyses.New_FftMtf()# SettingsnewWin_Settings = newWin.GetSettings()newWin_Settings.MaximumFrequency = 50newWin_Settings.SampleSize = ZOSAPI.Analysis.SampleSizes.S_256x256FFT MFT Window appears.And afterwards# Run AnalysisnewWin.
