Web25 Feb 2024 · In TEM, the sample is placed in the middle of the microscope and electrons pass through the sample before being collected. TEM offers information on ultrathin samples' inner structure, while SEM records information about a sample's surface. The below table summarizes the differences between SEMs and TEMs. Scanning Electron … WebThe transmission electron microscope (TEM) operates on many of the same optical principles as the light microscope. The TEM has the added advantage of greater resolution. This increased resolution allows us to study ultrastructure of organelles, viruses and macromolecules. Specially prepared materials samples may also be viewed in the TEM. new member aaa offer
