What are the main differences between a light microscope and an electron microscope?
Light microscope and electron microscope are two different microscopes, both in the definition, classification, composition and structure of the difference.
1,Different definitions
Optical microscope (English Optical Microscope, abbreviated OM) is the use of optical principles, the human eye can not distinguish between the tiny objects magnified imaging, for people to extract the microstructure of the optical instrument information.
The application of electron microscope technology is built on the basis of optical microscope, optical microscope resolution of 0.2μm, transmission electron microscope resolution of 0.2nm, that is to say, the transmission electron microscope in the optical microscope on the basis of the magnification of 1000 times.
2,Different classification
Optical microscope has a variety of classification methods, according to the use of the number of eyepieces can be divided into trinocular, binocular and monocular microscope; according to whether the image has a sense of three-dimensional can be divided into stereoscopic vision and non-stereoscopic visual microscope; according to the observation of the image can be divided into biological and metallurgical microscopy, etc.; according to the principle of optics can be divided into polarised, phase contrast and differential interference contrast microscope.
Electron microscope can be divided into transmission electron microscope, scanning electron microscope, reflection electron microscope and emission electron microscope according to the structure and use.
