GENERAL HISTOLOGY

Detailed explanation-1: -The main difference between SEM and TEM is that SEM creates an image by detecting reflected or knocked-off electrons, while TEM uses transmitted electrons (electrons that are passing through the sample) to create an image.

Detailed explanation-2: -Today there are two major types of electron microscopes used in clinical and biomedical research settings: the transmission electron microscope (TEM) and the scanning electron microscope (SEM); sometimes the TEM and SEM are combined in one instrument, the scanning transmission electron microscope (STEM):

Detailed explanation-3: -There are two types of microscopes i.e. Simple microscope and Compound microscope, where simple microscope is made up of single lens, compound microscope comprises of combination of lens.

Detailed explanation-4: -There are two main types of electron microscope – the transmission EM (TEM) and the scanning EM (SEM).

Detailed explanation-5: -The two main types of electron microscopes are the transmission electron microscope (TEM) and the scanning electron microscope (SEM).
