Simulating PTFE Integrating Sphere

Hello,I’m trying to simulate a PTFE Integrating Sphere using the predefined macro that we can find in sample files ...\Zemax\Samples\Non-sequentional\Miscellaneous\Integrating Sphere.zmxI was able to change dimension of sphere and port but im finding the following problem:1. How can I change the material MIRROR in PTFE?2. Can I inserti a material inside the sphere?3. How Can I calculate the number of refraction inside the sphere and the number of photons that reach the detector?4. How Can I simulate the Homogeity inside the Sphere?5. The detector viewer doesnt work, how me always the same results….Why?A guide about simulating an integrating sphere can help me so much...Thanks for the support.The code is as attachments.Best Regards.

How to use the GETTEXTFILE function with an NSC detector

Is there a way to to use the GETTEXTFILE function with an NSC detector? I’m running into the same issue, and couldn’t figure it out from the help page of the function. I’m currently using SAVEWINDOW from a detector window opened to the text tab and getting the same message.[Mod note: moved the post to a new forum thread.]

Total power and total flux

Hi! I’m calculating the energy inside a surface with LEDS with different detectors: volume detector, sphere as detector, volume pipe as detector… but I can’t get the same values across them… I don’t know why if I hace the same system…From objects as a detector I get total power, but from volume detector total flux (all of them in mW); is this the same?When I take a value from the matrix in volume detector, what is this? flux, power¿?This is my file, I calculate the three detectors individuallyThanks in advance,Carmen

ZPL Nuances & Best Practices

Hey Community,I’m starting this thread as a place to document some of the “pitfalls” of the ZPL language.  The ZPL is extremely powerful but since OpticStudio is trying to create a new language, the parsing is sometimes problematic.Variable NamesYou can actually assign a value to a number (the ZPL treats the number as a variable name).  So while OpticStudio won’t throw an error, you should be very careful when picking variable names:PRINT 1 + 2 # answer is 31 = 2PRINT 1 + 2 # answer is 4FOR LoopsThere is always round-off when dealing with decimals and this becomes especially true when trying to use a decimal step size in a FOR loop.  Rather than using decimals as either the start, end or step size, you should keep these as integers and convert to decimals inside the FOR loop:RecommendedFOR i = 0, 10, 1 px = i / 10NEXT Not RecommendedFOR i = 0, 1, 0.1 px = iNEXTSpeed Up CalculationsAll calculations via the ZPL force an update to both the GUI and the core code.  Pushing data to t

ZPL get FICL

Dear Experts,I am trying to read FICL in ZPL. Being new to ZPL I have simply tried this: vec1(1) = 1vec1(2) = 1vec1(3)=1vec1(4)=1vec1(5)=0vec1(6)=0.0366vec1(7)=0vec1(8)=0vec1(9)=0vec1(10)=0vec1(11)=0vec1(12)=0vec1(13)=0vec1(14)=0vec1(15)=0vec1(16)=0vec1(17)=0vec1(18)=0vec1(19)=1f=FICL(1)PRINT "FICL=",f, However, this returns always zero. I could not find any example or any more detailed explanation of ZPL FICL. Are there also several values returned by FICL, like SYSTEM and RECEIVER Efficiency? Can I set the specific configuration to return FICL?Many thanks for some explanation or a hint to an example file.Markus

Quickfocus in ZPL

Hi, I’m a bit confused that when I run the quickfocus command in ZPL, Zemax doesn’t always give me the same value, somehow I had to run my macro twice to get to the correct back focal length (my macro also changed wavelength and field setting). Is it normal to have this? Also, what would be a solution to fix this in the macro? I tried having quickfocus command twice inside the macro but it doesn’t help. Thank you very much.[Mod note: moved to more appropriate forum for ZPL related discussions.]

How to define a fiber output for a source Gaussian

I have a very simple question. How could I define a source Gaussian out from a single mode fiber, which core size is 4 micro, NA =0.12. I know the beam size (diameter) should be set to be MFD, how to put the parameter for position? should I put the parameter of the position as  Rayleigh distance Zr? or should I use MFD/(2*NA)? Thanks for your answer in advance.

How to change settings in Ima for GETTEXTFILE

Hi, I am  trying to calculate multimode fiber coupling efficiency by using Geometric Image Analysis through GETTEXTFILE, and I want to do this for different fields and wavelengths. I am trying to change field# and wavelength# by MODIFYSETTINGS, but looks like these two parameters are not allowed to be changed. Following is the list of parameters that MODIFYSETTINGS provides:  I wonder if anyone knows how to make the changes so I can do this calculation using ZPL. Thanks!Jizuo

How to iteratively change the clear semi-diameter of a component and save the resulting wavefront map to a file?

Hi everyone, I’ve recently started using OpticStudio. Currently, I’m trying to incrementally change the clear semi-diameter of a surface within my system. I know this can easily be achieved with a FOR loop.However, for each iteration, I hope to save the resulting wavefront map. Unfortunately, using GETTEXTFILE within a loop does not appear to work as intended, as the FOR loop seems to run as normal, but does not create the required files. I’ve attached my code. If there’s any mistakes or changes that need to be made so that the solver iterates over the semi-diameter values and saves the wavefront map at each step, just let me know. ! Setting the desired format.FORMAT 1 INTFOR i, 0, 6, 1    ! Reducing the clear semi-diameter by 5 lens units per iteration.    CLR_SEMI_DIAM = 52 - i*5    ! Returning the new clear semi-diameter to the editor.    SOLVERETURN CLR_SEMI_DIAM    ! Setting the output filename.    FLNM$ = "F:\LGS_104_Wavefront_Map_" + $STR(i) + ".txt"    !

Ray intensity sequential mode Apodization

Hello,How can I obtain the intensity of single rays (either using ZPL or API) when the apodization is part of a user-defined surface?I used the “us_filt1.dll” example provided with the Zemax distribution and set G>0. The APOI(x,0) operand returns 1.0 for all positions of the pupil (0<x<1), despite the apodization applied in the dll. Thanks!

Rounding numeric values when creating a ZPL macro

Good afternoon.I have a question about working with numeric variables when writing an ZPL macro. Is it possible to round the values assigned to variables with the required accuracy? I'm looking for functions similar to (FLOOR.MATH) and (CEILING.MATH) in Microsoft Excel. I understand that i can create a loop that allows me to sequentially compare the value of interest with i and i+1 value. I would like to create an ZPLM operand using rounding, so it seems to me that this way will slow down the optimization, especially with a high degree of rounding accuracy.As an example, we can discuss the case where the value 24.432 needs to be rounded up to 24.0 or 24.5.

Optimization operand name in ZPL code

Good afternoon! I am studying the ZPL macro language in order to simplify the analysis of data in the optimization process. In the macro being developed, I would like to implement the function of sorting optimization operands by their contribution. I know that such information is in the "" section, but I'm interested in the implementation in the ZPL language. There are no problems with the sort itself, I use the IF-THEN conditions in sequence, however, I cannot find a way to display the name of the operand by its ID code. Initially, I thought that the numerical function OPER(…,1) could give me the name of the operand in the string, however, as it turns out, this numeric function returns the ID code of the operand. Could you help me? Thanks

How to modify the POPD beam setting using ZPL macro

I had a post in Chinese but maybe this helps more people who wants to simulate the tolerance of their systems using ZPL. 如何使用ZPL改变POP中的beam和fiber数据 | Zemax CommunityThe MODIFYSETTING can be applied on the .CFG which has the same name of your design file and locates under the same directory of your file. This is the file that the POPD reads. You have to manually click the SAVE button to generate this file first. If we modify the POP.CFG, it does not work.Here is the sample ZPL code.popCFG$ = "C:\Users\Desktop\Fiber Coupling.CFG"MODIFYSETTINGS popCFG$, POP_FPARAM1, 0.005MODIFYSETTINGS popCFG$, POP_FPARAM2, 0.005OPENANALYSISWINDOW POP, popCFG$PRINT MFCN()The OPENANALYSISWINDOW may not be necessary for certain users. When I run the test, I need this line to activate the modification on this CFG file.
