Surface chemical analysis -- Auger electron spectroscopy and X-ray photoelectron spectroscopy -- Determination of lateral resolution
This standard has been revised by ISO 18516:2019
ISO 18516:2006 describes three methods for measuring the lateral resolution achievable in Auger electron spectrometers and X-ray photoelectron spectrometers under defined settings. The straight-edge method is suitable for instruments where the lateral resolution is expected to be larger than 1 micrometre. The grid method is suitable if the lateral resolution is expected to be less than 1 micrometre but more than 20 nm. The gold-island method is suitable for instruments where the lateral resolution is expected to be smaller than 50 nm.
Annexes A, B and C provide illustrative examples of the measurement of lateral resolution.
