title: A crystalline test specimen for checking the performance of high-resolution electron microscopes.
abstract: A thin single crystal (001) film of gold with a favourable perforation is described. Examples of its versatile applications to test procedures and calibrations in high-resolution electron microscopy are illustrated. The advantage of such gold films mainly results from the good visibility of dark-field/bright-field image displacements at perforation edges in well defined crystallographic orientations.
