WebThe TEM has allowed us to see individual atoms and structure of cell nuclei. The scanning electron microscope (SEM) provides images by using secondary electrons produced by the primary beam interacting with the surface of the sample (see Figure 2). The SEM also uses magnetic lenses to focus the beam onto the sample. Web1) The light from your sample enters the microscope through a condenser lens, reducing its numerical aperture (NA). The objective lens then moves closer to the model to collect more light. In this case, you will see an increase in magnification because more light is coming into your field of view and less going out.
