Web12 de abr. de 2024 · Bright field, annular dark field (ADF), and high-angle annular dark field (HAADF) STEM imaging are primarily used for sample navigation and feature size measurement. STEM images up to one gigapixel can be acquired quickly (up to 10 Mpixels/sec) with the integrated scintillator-based bright field and ADF/HAADF detectors. WebDark-field microscopy(also called dark-ground microscopy) describes microscopymethods, in both lightand electron microscopy, which exclude the unscattered beam from the image. As a result, the field around the specimen (i.e., where there is no specimen to scatterthe beam) is generally dark.
