1. Different definitions

The application of electron microscope technology is based on the optical microscope. The resolution of the optical microscope is {{0}}.2μm, and the resolution of the transmission electron microscope is 0.2nm. That is to say, the transmission electron microscope is magnified 1000 times on the basis of the optical microscope.

2. Different categories
According to the number of eyepieces used, it can be divided into trinocular, binocular and monocular microscopes; according to whether the image has a stereoscopic effect, it can be divided into stereo vision and non-stereo vision microscopes; according to the object of observation, it can be divided into biological and metallographic microscopes; according to the optical principle, it can be divided into polarization, phase contrast and differential interference contrast microscopes.
