What distinguishes an electron microscope from an optical microscope
The definition, categorization, and composition of an optical microscope and an electron microscope are different from one another.
1. various definitions
An optical device known as an optical microscope (abbreviated as OM in English) is used to magnify and picture minute things that are invisible to the human eye so that individuals can gather information about their microstructure.
The optical microscope serves as the foundation for the application of electron microscopy technologies. Both the optical and transmission electron microscopes have resolutions of 0.2 nm and 0.2 m, respectively. In other words, the transmission electron microscope is 1000 times more powerful than an optical microscope.
2. Different categories
The classification of optical microscopes can be done in a variety of ways. They can be divided into trinocular, binocular, and monocular microscopes depending on the number of eyepieces used; stereoscopic vision and non-stereoscopic vision microscopes depending on whether the image has a stereoscopic effect; biological and metallographic microscopes depending on the object of observation; and polarized light, phase contrast, and diffractive optical microscopes depending on the optical principle
According to their constructions and applications, electron microscopes can be classified as transmission electron microscopes, scanning electron microscopes, reflection electron microscopes, and emission electron microscopes.
3. A distinct composition structure is used.
The objective lens, eyepiece, mirror, and condenser are the four essential components of the microscope's optical system. In a wide sense, it also comprises slides, coverslips, lighting sources, and filters.
Three components make up an electron microscope: a lens barrel, a vacuum, and a power supply cabinet.
