Scanning objective lens magnification
WebMay 9, 2024 · Because of the difficulties of focusing secondary electrons, which have a wide range of emission energies, the most practical way of forming a SE image is to use a scanned-probe method, as in the scanning electron microscope (SEM) or STEM. The image resolution is then largely determined by the properties of the probe-forming objective lens.
