Overview of Microscopes

The phrase microscope derives from the Greek, namely the term micron = small and scopos = purpose. General, it is a tool used to view items that are too small to be seen by the naked eye. It really is known that the producers of the microscope for the first time were two German scientists, particularly Hans Janssen and Zacharias Janssen (father-son) in 1590.

This finding encouraged other scientists, including Galileo Galilei (Italy), to help make the same tool. Galileo completed it in the year 1609, the fantastic microscope was known by the name Galileo. This kind of microscope used optic lenses, so it was called optical microscope. To get more details about microscope browser https://www.einstinc.com/wpcproduct/eclipse-lv100-polarizing-microscope/

Certainly, microscopes that had been assembled from optical lenses had limited ability in growing the size of the target. Theoretically, the wavelength of light was only up to about two hundred nanometers. Therefore, this optic lens-based microscope could hardly see the size below 2 hundred nanometers.

To see the object size less than 200 nanometers, you needed a microscope with a short wavelength. From this idea, in 1932, there was an electron microscopic lens. For that reason, it had a zoom lens capable of a subject (resolution) that was higher than the optical microscopic lens.

Actually, in the magnifying function of the target, the electron microscope also used lenses, although not from the sort of glass as you could see in the optical microscope, it was from the sort of magnets.
