Figure 1
The different contributions to the spectrometer resolving power for (a) LEG and (b) HEG as a function of photon energy (given in different orders on the abscissa). Variations of source spot size (blue) and CMOS incidence angle (red) are also shown. Note that aberrations (yellow) do not play any role for the LEG and thus do not appear in the shown resolving power range in (a). |
