Settings for the FFT Through Focus MTF analysis.

For an in depth explanation of the parameters, see the OpticStudio user manual.

Attributes:

samplingstr | int: The pupil sampling, either string (e.g. “64x64”) or int. Integers will be treated as a ZOSAPI Constants integer and must be greater than or equal to 0. Defaults to “64x64”.
delta_focusfloat: The Z-axis range or optical power range, depending on the optical system. Defaults to 0.1.
frequencyfloat: The spatial frequency for which the MTF is calculated. Defaults to 0.
number_of_stepsint: The number of steps in the focus range. Defaults to 5.
wavelengthint | str: The wavelength to use in the MTF. Either ‘All’ or an integer specifying the wavelength number.
fieldstr | int: The field to use in the MTF. Either ‘All’ or an integer specifying the field number.
mtf_typezospy.constants.Analysis.Settings.Mtf.MtfTypes.Modulation: The MTF type (e.g. Modulation) that is calculated.
use_polarizationbool: Use polarization. Defaults to False.
use_dashesbool: Use dashes. Defaults to False.
