Microbeam analysis. Analytical electron microscopy. Methods for calibrating image magnification by using reference materials with periodic structures Ingestion-build-107062 The specifications for welding filters1 Scope This document specifies a calibration procedure applicable to images recorded over a wide magnification range in a transmission electron microscope (TEM). The reference materials used for calibration possess a periodic structure, such as a diffraction grating replica, a super lattice structure of semiconductor or an analysing crystal for X ray analysis, and a crystal lattice image of carbon, gold or silicon.
