Hi Daniel,

Thank you for discussion. Unfortuantely, this script only works with uncompressed ZRD. The format in the compressed ZRD is IP that cannot be shared publicly.

I suggest you read the compressed ZRD using ZOS-API. You can find a good example in the Zemax installation in \Documents\Zemax\ZOS-API Sample Code\Python\PythonStandalone_05_Read_ZRD_File.py.

I hope this helps.

Please let me know if you have any questions.

Thank you.

Hi Jimmy,

Thank you for checking!

Unfortunately I don’t have an example for MATLAB. I think the key point is you need to know how to read/write a binary file and parse it as double or string in MATLAB. I just had a quick search and can see corresponded tutorial. With this reference, I think it’s possible to convert the code in Python to MATLAB.

I’m sorry for inconvenience. Please let me know if you have any further question. Thank you!

Best regards,

Michael

Hi Jimmy,

Please do not hesitate to let me know if still have any question.

Thank you.

I have an active license, do I need to open a support ticket? 

 

Hi Jimmy,

Yes, that’s a little weird if you are End User of a supoprted license but cannot use the following link.

Please feel free to send a support ticket so that we can help to see if there is any issue in your account and send the file directly to you in the meantime.

Thank you.

Hi Michael,

This is great!  Thank you for making this.  However, for reading the ZBF files, it looks like there’s just header information.  Have you done any work to extract the actual E-field data?
