What is Microscope definition/concept

The small reality , whether inert or alive, is imperceptible to the human eye. However, the microscope is an optical instrument that allows you to know everything that exists, however small it may be. This is possible because this device has lenses that enhance the image making it possible to observe everything that is beyond the reach of the human eye. In this way, a sperm, a mite or a hair can be fully visible under a microscope.

Even so, for something to be visible by this instrument it must be very thin and diffused for light to pass through and allow you to observe its image. In addition to the lens system , it must incorporate a mechanical system to articulate the lens, focus the object and measure light intensity.

Obviously, every microscope includes an illumination mechanism with connection to a light system, a condenser and a diaphragm.

Different types and most frequent uses

The compound microscope magnifies the image of objects under observation up to a thousand times and is what is most used in basic research. Electronics provide magnifications in excess of a thousand and are generally employed by specialists in specific fields.

Microscopes are most used in the scientific field . In addition, they are used in the teaching and practice of medicine, biology, forensic investigation and bacteriology. Also, they are essential tools to carry out cultures of microorganisms or parts of organisms .

A historical brushstroke

The invention of the microscope is not without controversy. For some, its real inventor was Galileo Galilei, who called his first device the ochiollino, which in Italian means small eye. Other historians of science claim that it was the Dutch Janssen brothers who invented it. In any case, the first microscopes consisted of a combination of two unique crystals that multiplied the size of objects tenfold. Dutchman Anton van Leeuwenhog incorporated new technical elements, enlarging the images 300 times.

Since its origins, the term microscope was used to oppose another invention of the same period, the telescope. This new invention led to the emergence of a new scientific discipline , microbiology . This discipline is divided into three areas: virology, parasitology and bacteriology. All of them study microorganisms that are visible only through a microscope.
