Polycapillary-boosted instrument performance in the extreme ultraviolet regime for inverse photoemission spectroscopy: erratum

We correct values and figures for the resolution of the spectrometer, as proposed in [Opt. Express 25, 31840 (2017)]. The new results take into account previously unknown, incoherent phase fluctuations, caused by the polycapillary lens (PCL), and estimate the realistic performance of the instrument.(c) 2022 Optica Publishing Group under the terms of the Optica Open Access Publishing Agreement
