During school you may often use a microscope in a lab school to see objects that are very small in size which can not be seen by the eye, but do you know the history of the microscope?
The microscope is an optical instrument that can be used to see or observe objects that have a very small size. The microscope was first discovered in 1590 by Zacharias Jansen. Through the invention of this microscope, everyone can see objects that are very small.
Along with the advancement of technology, in 1665 a British scientist named Robert Hooke designed the compound microscope and has its own light source. Robert Hooke’s microscope design has the capability of objects up to 30 times magnification. Homemade through a microscope, Robert Hooke can find a cell on a wooden cork observed.
But at the same time, ie 1668 to 1677, a Dutch scientist named Antonie Van Leeuwenhoek develops single-lens microscope with a magnification power of objects up to 270 times larger than actual size. Antonie Van Leeuwenhoek succeeded in observing the red cells, yeast, bacteria and protozoa under a microscope design. Thanks to its findings, the unwitting Van Leeuwenhoek became the first person to see the bacteria.
Modern microscopes are the simplest and is used today is a light microscope. Light microscope can make objects up to 1,000 times magnification. The microscope works by passing light is also being observed. Furthermore, the light will be deflected by the lens so as to form a shadow image of an object larger than the original. Then the shadow projected onto the eye of the observer, so the observer can see the object clearly observed. In addition it can be observed directly, the observations using a microscope can be printed. The printed picture is called micrograph.
Along with the continued development of science in the field of technology, even the more developed microscope with magnification capability resulting increase. So that in 1933, a physicist from the Germans, Ernst Ruska, managed to create the first electron microscope. In contrast to light microscopy, electron microscopy does not use light, but it uses electrons to look at the structure of small objects.
TEM microscope magnification of the object can reach 500,000 Mirkoskop TEM can create an image by sending electrons in extremely thin slices of the specimen. So that the microscope can be used to look inside the cell structure.
Similarly, a review of the history of the invention of the microscope and its usefulness in the world of science, hopefully this article can be useful for you all in science, thanks.
