The development of microscope has gone through three stages (/kloc-composite microscope in the 7th century) (/kloc-optical microscope in the 9th century) (electron microscope in the 20th century).
I. Optical microscope
The optical microscope was invented by Zhan Sen and his son in the Netherlands in 1590. Nowadays, optical microscopes can magnify objects by 1600 times, and the lowest resolution reaches 1/2 wavelength.
Second, the electron microscope

2. 193 1 year, Ernst ruska invented an electron microscope, which completely changed biology. This enables scientists to observe objects as small as a millionth of a millimeter. 1986 won the Nobel Prize.

Historical evolution of microscope;
In 1590, Z. Zhan Sen of the Netherlands (Zhan Sen) and Italian glasses manufacturers have made magnifying glasses similar to microscopes.
1833, Brown: Observe violets under a microscope, and then publish his detailed discussion on the nucleus.
1876, Abbe: Analyze the diffraction effect of the image when it is imaged in the microscope, and try to design the most ideal microscope.
Zeiss (1886): It broke the theoretical limit of general visible light, and his invention-Abbey Type and a series of lenses opened up a new world for microscopists to interpret images.
1930, lebedev: The first interference microscope was designed and matched. In addition, the phase contrast microscope was invented by zernike in 1932.
1952, Nomarski: the optical system of interference phase difference was invented. This invention is not only patented, but also named after the inventor himself.
