ISO 18516:2006 PDF

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.
