The microscope is one of the most important inventions in history. It is currently used in a wide range of fields, such as medicine or biology, among many others. The inventor of this instrument is considered to have been Zacharias Janssen. Born in Middelburg (Netherlands) in 1588, his family was dedicated to the manufacture of glasses, so that since childhood he had contact with this industry. It is not known for sure what is the origin of the microscope despite the large number research that has been carried out, but today it is considered that it was Zacharias Janssen who invented the compound microscope, which consists of two lenses, most likely with the help of his parents at the end of the 16th century. At that time I was very young, so it is possible that Hans Lippershey made the first microscope, and then Zacharias Janssen took over the production. Legend has it that Zacharias Janssen discovered the microscope by chance. When he was a child he played with another boy whose glasses were broken in his family’s workshop. The little ones saw how, if they held the glasses right in front of them towards the weather vane of the local church, they could see all the details.Now, there are those who believe that it was not really Zacharias Janssen who discovered this instrument. If we take into account the personality of the young man, he had a reputation for being dishonest since he made a great fortune by forging gold, silver and copper coins. Of course, the first microscopes in history were very rudimentary, and they had little to do with those we know today.They consisted solely of a tube 45 centimeters long and 5 centimeters in diameter, which had a convex lens at each end. It had up to nine magnifications, although it depended on the aperture of the diaphragm. What there is no doubt is that, thanks to the first microscope, many things began to be seen that until then were completely unknown. Today, thanks to it, scientists can observe viruses and bacteria in all their splendor. In addition, there are different types of microscopes, each with a specific purpose: ultraviolet light, dark field, probe, force, virtual …
