Detailed explanation-1: -Electron microscope has a high resolution power.
Detailed explanation-2: -Out of all types of microscopes, the electron microscope has the greatest capability in achieving high magnification and resolution levels, enabling us to look at things right down to each individual atom.
Detailed explanation-3: -TEM users can magnify their samples by more than 50 million times, while for the SEM, this is limited to 1–2 million times. However, the maximum field of view (FOV) that SEMs can achieve is far larger than TEMs, meaning TEM users can only image a very small part of their sample.
Detailed explanation-4: -The TEM offers higher resolution ( 0.2 nm) than SEM, and can even reach near-atomic resolution for HR-TEM. Additionally, TEM provides information on both element and compound structure (i.e., crystal structure, elemental information and morphology).
Detailed explanation-5: -Electron microscopes have a high resolving power, 250 times that of light microscopes, and magnify objects by 100, 000 to 300, 000 times.
