The optical microscope came to mark a before and after in the history of technological advances. This device allows you to observe in an enlarged image objects that would be impossible to observe with the naked eye. Learn below which are the most powerful optical microscopes in the world
The optical microscope is considered one of the most important technological inventions of all time. It is believed that his arrival in the world marked a before and after in the history of science, especially in the area of biology and medicine. From its first creation to the present, there have been many modifications that this device has undergone.
When we talk about an optical microscope, we basically refer to a device by which it is possible to observe in an enlarged size objects that would be practically impossible to analyze with the naked eye. Thanks to the light microscope, many scientists and researchers around the world have been able to start studies on topics that previously could not be analyzed.
Today there are some models of optical microscopes and each of them has special characteristics and qualities. In this opportunity, you will be able to learn about the most powerful optical microscopes in the world and their positive impact on sciences such as biology and medicine.
It is said that the optical microscope was in charge of starting the era of microscopy in the world, specifically during the 17th century. It is described as the most basic type of microscope of all and its function consists mainly of a set of lenses and the use of visible light to raise the size of a certain objective.
Light microscopes have advanced over the years. Today there are much more powerful models than those created at first. It is believed that the highest power optical microscopes in the world were created in 2011, after research carried out by a group of scientists in the United Kingdom, especially in Manchester.
One of the most attractive innovations of this new light microscope is the glass beads used. The glass spheres collect the evanescent waves from the samples, gathering the light and redirecting it onto a standard microscope lens. The most powerful optical microscope in the world allows to observe elements of 50 nanometers (0.00000005) in size, increasing its original size up to 20 times.
Thanks to this new invention, it is now possible to more accurately detect elements that were previously not possible, for example, human cells, live viruses, bacteria and biomolecules. There are many models of optical microscopes that offer great advantages and functions. Here are some of the most popular models on the market:
- Telmu 40-1000X Lead: A model that offers multiple eyepieces and objectives that can be adjusted in the best way. It also has a dual-color light source, meaning you can adjust the brightness.
- Uscamel 40-400X: A model created especially for children
- Maxlapter 1000X
- Bresser Biolux NV 20x-1280x
History of the light microscope
The arrival of the optical microscope marked a historical precedent in the technological development of the world. Although it is true before the invention of the microscope, it was already common to use lenses in order to observe a certain element in an enlarged way, the arrival of the microscope brought further progress to important sciences such as biology and medicine.
Before the microscope there was what is known today as magnifying glasses. They were very useful tools that allowed us to appreciate different smaller objects in an enlarged way.Each of the advantages of the magnifying glass was extensively analyzed by various scientists, including Roger Bacon during the 13th century
However, it was at the end of the 16th century that the first microscope invented in the world was known. It was an invention developed by the Dutchman Zacharias Janssen, a renowned manufacturer of glasses at the time. He is credited with the invention of the first compound microscope in history.
Janssen's invention consisted of a tuba-shaped apparatus that had two lenses on its structure (hence the name microscope). Through this device it was possible to expand the vision of different objects. It was even said that this first microscope invented had the power to increase up to nine times the original size of the objects observed.
Years later the Italian Galileo Galilei also created his own version of the microscope by combining a convex and a concave lens. Galileo's invention occurred practically during the same dates that Janssen created his model, for that reason it is that until today there continues to be much confusion as to who was the true inventor of the microscope.

The only thing clear so far is that Giovanni Faber was the first man in history to make use of the term microscope for the first time. He did it in the 1625s with the intention of referring to this type of apparatus. P>
During the 17th century, many scientific works developed from the use of the microscope emerged. One of them was the work "Micrographia", by Robert Hooke in 1665 and where there are illustrations of plants and insects observed through the microscope.
Function of the optical microscope
Since its creation, the optical microscope has been characterized by having countless advantages and uses, which have been adjusted over time until a perfect and efficient model has been achieved. The main function of the microscope is to increase the image of objects that seem impossible to detect to the naked eye, but how does it do it?
The operation of a microscope is based on the property of some materials that allow changing the direction of light rays, which allows manufacturing lenses capable of converging or diverging light rays. After the combination of these lenses, an enlarged image of any object can be produced.
The production of an enlarged image with the use of the optical microscope is possible, firstly, through the use of different lenses. Some of them mounted on the microscope object and others on the eyepiece..
