I have a macro calling GETPSF for various thicknesses to the focal plane, and I am getting np = -3, 'General Error' returned when I use Gaussian apodization.
I have checked that the FFT PSF is calcualting without error for the same thicknesses as are in my macro.
What else can cause a 'General Error' in response to a call to GETPSF?
A General Error is when the PSF cannot be computed by OpticStudio.
For example, when you get this error, it will return np=-3.
So would you mind sharing your examle with us? Feel free to open a case or send us an email at support@zemax.com to share it.
Thank you!
