ZPL to save geometric image analysis images in a loop

Hi, I’m trying to use ZPL to run a couple of loops and save geometric image analysis. This loops aim to change the field and wavelength in the settings of the image, but I cannot make it work. If I go for the text-only saving option, it doesn’t change either. To guide you into the code, first I define the x and y of the fields:DECLARE setxfields, DOUBLE, 1, 9DECLARE setyfields, DOUBLE, 1, 9setxfields(1) = 0.0setxfields(2)=9.68938        …setyfields(1)=-0.0    setyfields(2)=-0.034… Then define the folders and filenames and then start the loopFOR wave2, 1, 9, 1    FOR field, 1, 9, 1    field_x = setxfields(field)    field_y = setyfields(field)    SETSYSTEMPROPERTY 101, 9    SYSP 102, 1, FLDX(field)    SYSP 103, 1, FLDY(field)    SYSP 202,1,WAVL(wave2)    window=WINL()    OPENANALYSISWINDOW "IMA"    UPDATE ALL    filename$ = arm$+"_"+mode$+"_"+"test_wave_"+$str(WAVL(wave2))+"_field_"+$str(field)+".bim"    filename2$ = arm$+"_"+mode$+"_"+"test_wave_"+$str(WAVL(wave2))+"_field_"+$str(field)

how to get peak irrandiance from NSC detector through ZPL Macro

Hi Sir/Madam,I am trying to get the peak irrandiance through ZPL language, but seems do not have command fit my purpose.I am thinkging if I could use NSDD to get flux value in position space for each pixel# and compare each value with a command like “maximun” to get the peak one in a array, then I still could reach my purpose. But is there any command for me could do it to get maximun value? and how should I use it? SincerelyDavis

A question about create automatically optimization wizard table by ZPL

HiI'm trying coding a ZPL script to create an automatic optimization wizard table.My target optimization wizard table was show as below picture.   Here is producing optimization wizard table by running my ZPL script.Unfortunately, they have three differences by comparing the two created optimization wizard tables and making numbers on the above pictures. Here is a list of the parameter value for differences. This is show the partial screenshot of my ZPL script, the code also attached to set Merit Function.zip. What kind the command settings/paraments were missing in this ZPL script? That can be fixed for the three differences.

"GetNSCPosition" is not recoganize in ZPL

I applied a solve on position z by 'SOLVETYPE'. Then I need to refer to the result of solve, i.e. the position os z.  I am trying to using 'GETNSCPOSITION'. According to the EXTENSION DATA ITEMS, this should return the object position and angle and material. However, the viewer shows 'Unknown symbol GETNSCPOSITION.' The similar command 'SETNSCPOSITION' works fine. But not the GETNSCPOSITION. It seems in the editor, it does not recoganize it as a legal command Can anyone help something is wrong? Thanks.

Suppress Zemax Message during macro execution

Hi, I'm running Zemax Optic Studio Professional, version 20.2.2. Whenever I'm working with large pixel arrays, or high (> 1024 x 1024) sampling in physical optics propagation, and my detector viewer/beam file viewer is set to text view, I get a message box saying 'Text is too long to display. Use Copy All or Save As' to retrieve the entire file'.  This message box doesn't cause a problem as I'm exporting the data in a macro anyway, but it means that during a long macro where I'm running POP multiple times, I have to constantly watch OpticStudio as it pauses the macro until I dismiss the message box, which is obviously impractical.  Is there a way to either  a) Increase the maximum allowed text file to be displayed within OpticStudio, or b) Suppress the message box, as the data export is absolutely fine Thank you!

How to get the column number calling a ZPL macro?

Hi,In a ZPL macro one can get the object number that’s calling the macro as solve with SOSO(1), but how do I get which column that’s calling the ZPL macro?I want to use the same macro for solving both the Z and the Y position of an object so I don’t need maintain two separate macros.Regards,Hans

Geometric ESF vs FFT ESF

In otpicstudion I am using, there are two way to get edge spread function. One is gemetric ESF, and the other is FFT ESF. I guess that FFT ESF are based on FFT, but don't know how the geometric ESF is calculated. Is it based on raytrace method rather than wave property of light?

SETNSCPOSITION/ SETNSCPARAMETER In ZPLM

Hello, I want to push into my model an input file with data regarding new position/ parameters.When I execute the ZPL code through the GUI (Programing>Edit/Run, F9) it works just fine, but when I try to execute it through the merit function with a ZPLM row it seems that the SETNSCPARAMETER/ SETNSCPOSITION just isn’t working.I know the MFE is executing the ZPLM since I made a debug output which looks just fine, feels like I’m missing something very basic.Code snippet:OPEN INPUT_FILENAMEOUTPUT OUTPUT_FILENAMEREAD NUM_OF_PARAMS NUM_OBJPRINT NUM_OF_PARAMS, " ", NUM_OBJFOR II, 1, NUM_OF_PARAMS, 1 READ PARAM_NUMBER PARAM_VALUE PRINT PARAM_NUMBER, " ", PARAM_VALUE SETNSCPARAMETER 1, NUM_OBJ, PARAM_NUMBER, PARAM_VALUENEXTCLOSE An input/output example of the code above:## INPUT ##3 181 50 2 50000.0 3 0.005## OUTPUT ##3.0000 18.00001.0000 50.00002.0000 50000.00003.0000 0.0050 Edit: Wanted to point out that my ZPL files are located in Zemax/Macros

Saving elements of a vector in ZPL is very slow!

Hi, I made a ZPL macro that uses GETPSF to retrieve a PSF to a vector and then saves the vector to a file with a FOR loop on the vector elements. The saving part is extremely low! Is there a better way to save the results? I tried doing the same thing with GETTEXTFILE but the speed is similar, and I lose control on file format and can't seem to find a file to set the parameters such as sampling size. Any help really appreciated! Thanks, Paolo

Surface Property Updating, but results not changing without manual refresh

Hello,   I am doing a polarizaiton analysis and am running into an issue when it comes to updating my surfaces. I have a short macro that updates the tilt about x for a coordinate break before a mirror, and the tilt about x for a coordinate break after a mirror. Then, I am using the OPEV function to get the transmission of a surface further in the system. The problem is, when I use the macro to udpate the tilts, the results don't show in the OPEV function unless I manually refresh the results. This will not work for me as I am working with a very large data set and thus need to be able to do it without manually refreshing. Just a simple example of the setup is given below.    SETSURFACEPROPERTY 8, 10, 3, 3 # sets the tilt about x before the mirror (surface 9) SETSURFACEPROPERTY 10, 10, -3, 3 # resents the tilt about x for the whole system, esentially just tilting the mirror in the whole system code_coda = OCOD('CODA') # defining the merit function code used to get th

Ignore errors in ZPL

Is there a way to ignore errors while running a ZPL, and keep it running? I have a ZPL that opens files and some files come up with the following error.   Zemax Error Message Cannot determine object coordinates! OK I select OK and the ZPL can continue running. But since I am running through many files this comes up often and doesn't continue until I select OK. Is there a way to ignore these errors and allow a ZPL to continue running? Without having to select OK each time? Thank you,

how to force an analysis window to read a changed/modified config file

I have a lens file open, with some analysis windows open.  Using ZPL, I want to loop through and change the .CFG file (this is for a detector window in non-sequential.).   I haven't done it yet, but I think this will change the settings:           ModifySettings (filename,DVW_FILTER, ‘new_filter_string”, ‘DVR’) , or something like that, once I get the quotes straightened out.     However, my question is:  How do I force the open analysis window to update with the new .cfg file? In ZPL Macro, there does not seem to be any command like:  LoadNewConfig(Filename, WindowNumber).    I know I might be able to open a new analysis window, but for reasons of being able to see what is going on, I'll save that for Option B. thanks for your time.    John

Calling a .ZPL macro from a tolerance script

Hello!TLDR: Is there a way to run a .ZPL macro from within a tolerance script? I’m trying to add and remove fields during the tolerance script used in my Monte Carlo simulation because I suspect this could make things run a little faster but so I made an “add_fields.ZPL” and a  “remove_fields.ZPL”. Context: Have a tolerance script that has a few optimizations and a final performance evaluation merit function is called. I don’t need all the fields for the optimization but I do for the final performance evaluation. So two questions…1)  I’m assuming more fields (especially with ray aiming) will slow down my nested optimizations even if I’m not calling all of the fields in the merit function, is this true? 2)  Any way to call the macros I made “add_fields.ZPL” and a  “remove_fields.ZPL”? Or alternatively, can I play around with SYSP during a tolerance script?

EFNO gives different result to that calclated in relative illumination analysis

Hello,I have a system with a non-circular aperture and therefore try to calculate its effective f number using the operand EFNO(effective f number). However, I get different results when using the operand EFNO, in comparison to the result given in the relative illumination analysis, despite the same setting is applied on both calculation. (wavelength 3 is 0.555µm, and field 1 corresponds to 0 y field)     As can be seen above, one gives a value of 4.13(EFNO), while the other gives a value of 3.85. I think the latter one should be correct, but the question is why does one get different results here, do these two use different algorithms for calculation? How can I calculate this value in a Zemax macro conveniently if the result provided by EFNO is not trustworthy….  Thanks a lot in advance!

Adding easing to animations

Hello everyone, I just wanted to share some work I’ve been doing today with adding easing to animations for OpticStudio.In March 2021, Dan Hill published his fine article: How do I create presentation quality graphics and animations? At the end of the article, Dan demonstrates how to produce a 360 degree animated GIF using ZPL.However, one may want to rotate an object over a smaller angular range, and go back and forth from the original position. If you were to do so naively using Dan’s approach, every frame would be at a fixed angular position from the previous one, and you would obtain a “linear” GIF. However, you can obtain a slightly different result if you apply an easing function. There’s an outstanding website, called https://easings.net/, that demonstrates how to make use of such easing functions and the website also includes the formulas necessary to calculate these easing functions.Let me demonstrate the result with an example first, and then show you the workflow I used.I wa

Why does the merit function have different values than when I run ray trace?

So I’m trying to optimize a design in Zemax non-sequential. However I’m noticing that there is a discrepancy between what the MF editor reports, and what I see from running ray trace and running detector viewer. My MF looks like the following: And I see that the total flux (line 7) is 0.619 out of .75. This is a very good number. So then I cancel the optimization, and perform a ray trace, and when I take a look at the detector viewer, I get the following:How can the MF editor be displaying 0.619, yet the total power, which I think is the same metric on the detector viewer is indicating 0.422?
