US 9,417,341 B2 · Device and method for determining the energetic composition of electromagnetic waves

Abstract

The present invention relates to a method and device for determining the energetic composition of electromagnetic waves. It is the object of the present invention to provide a method and device for X-ray spectroscopy that allows simultaneous detection of the individual energies at a comparatively higher resolution and/or across a comparatively wider energy range. According to the invention, at least one reflective zone plate (12) is used that comprises a multitude of predefined wavelength-selective regions (14) arranged next to one another, wherein the wavelength-selective regions (14) each include a multitude of reflecting arched portions (20), which extend exclusively and continuously across the respective wavelength-selective region (14).
