EnergyFilter

class marxs.optics.EnergyFilter(**kwargs)

Bases: FlatOpticalElement

Energy dependent filter with position, size etc.

Parameters:

filterfunccallable

A function that calculates the probability for each photon to pass through the filter based on the photon energy in keV. The function signature should be p = func(en), where p, en are 1-d arrays of floats with the same number of elements.

Examples

>>> from scipy.interpolate import interp1d
>>> from marxs.optics import EnergyFilter
>>> energygrid = [.1, .5, 1., 2., 5.]
>>> filtercurve = [.1, .5, .9, .9, .5]
>>> f = interp1d(energygrid, filtercurve)
>>> blockingfilter = EnergyFilter(filterfunc=f, position=[4, 1, 0], zoom=4)
