Electron Microscopes use electrons and not photons (light rays) for visualization. Disadvantage: Light microscopes can be used only in the presence of light and are costly. These processes can not be observed in real time using electron microscopes, as the specimen has to be fixed, and completely dehydrated (and is therefore dead). Though this is a significant amount of magnification, it is dwarfed by the electron microscopes ability to achieve a magnification of up to 250,000x. what is the differents between an electrick microscope and a non-electric microscope. confocal uses 1 photon to illuminate 1 specimen at a time with view only up to 100 mm while TPM uses 2 photon so you can view up to 1000 mm. This beam is focused with the help of electromagnets, employing the negative charge on electrons. The objective lenses can be rotated in order to change the magnification of the microscope. Not be be confused with electron microscopes. Illuminating source is the beam of electrons. SEM focuses on the samples surface and its composition, so SEM shows only the morphology of samples. Electrons have much a shorter wavelength than visible light and this allows electron microscopes to produce higher-resolution images than standard light microscopes. This beam is focused with the help of electromagnets, employing the negative charge on electrons. The light microscope is an instrument for visualizing fine detail of an object. Both living and dead organisms are seen through it. The key difference between light and electron microscope is that a beam of electrons is employed for magnifying the image of an object while visible light is used in the light microscope to magnify images of spotted areas of materials or biological specimens.
