Microscopy is a set of imaging techniques, therefore, there are different types of microscopes. Each microscope has its own properties, which makes it possible to use them in many scientific disciplines. There are 4 main types of microscopy: Optical microscopy, electron microscopy, probe microscopy, local probe microscopy and metalentil microscopy.

A scanning electron microscope (SEM) is a type of microscope that produces images by scanning a surface with an electron focus. Eligible samples for SEM are typically dehydrated or fixed in the case of cells, and can also be cryogenically fixed for lipid observation.
A transmission electron microscope (TEM) is a type of microscope in which an electron beam is transmitted through a sample to form an image. The sample is typically a section of tissue or cell. The main advantage of the MET is the resolution of the generated images.
Fluorescence microscopy refers to any microscope that uses fluorescence to generate an image.
Confocal microscopy is a type of fluorescence microscopy used to improve optical resolution and contrast, compared to the use of epifluorescence. Collecting images is typically slower than for other types of microscopy, however the scanning method is ideal for generating 3D images.
