Correspondence between achievable diffraction efficiency and related diffraction-broadened spectral resolving power. The points present the achievable diffraction efficiency for off-plane diffraction according to Fig. 2(b)[link] from the tested grating for a photon energy of E = 124 eV for the first three diffraction orders m as a function of the achievable spectral resolving power RP according to Fig. 2(d)[link]. The line presents the same aspect for in-plane diffraction, in which case the groove density can also be varied. Thus for a given spectral resolving power the presented diffraction efficiency is the ultimately possible diffraction efficiency for in-plane diffraction.
