High resolution tem images
WebElectrons have much a shorter wavelength than visible light, and this allows electron microscopes to produce higher-resolution images than standard light microscopes. Electron microscopes can be used to examine not just whole cells, but also the subcellular structures and compartments within them. WebHigh-resolution TEM requires that Δk be as large as possible, so it is important to understand image contrast in realistic cases where W(Δk) is not small. The waves …
