WebTransmission electron microscopy (TEM) is a high-resolution technique used to reveal structural details, size distribution, and morphology of nanoparticles made up of lipids and proteins and hard nanoparticles composed of metallic particles, carbon, or plastics. TEM is based on the interaction between a high-energy electron beam and a thin 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.
