Microscope and types of Microscope
Microscope and types of Microscope: Microscopes are a branch of science in which microscopic and non-microscopic organisms are enlarged through microscopes. It is not possible to see such organisms with ordinary eyes, in which reflection of light, refraction, diffraction and electromagnetic radiation are used.
Microscopy is used for the control of diseases and the discovery of new drugs in the world, optical, electron, and scanning probe microscopes are included in three popular branches of microscopy.
The invention of microscopes z. Janssen (Netherlands) did in the year 1590.
The microscope is believed to date from the beginning of the 17th century when scientists and engineers discovered lenses in physics. It was only after the invention of the lens that it became possible to see objects in their original form.
The Italian scientist Galileo first created simple microscopes in 1610, followed by two men who make the magnum opus for reading in the Netherlands, named “Hans Lippersche” and “Zacharias Jansson”, together they designed the telescope. Is considered the inventor of.
The first optical microscope was invented where is also known as Light Microscope, it is used to look at the organs of animals.
There are two types of microscopes.
- Simple microscope and
- Combined microscope
- Simple Microscope: A simple microscope is a convex lens of short focus distance, which is mounted in a circular frame with a handle.
Simple microscope principle
By placing an object between the center of light and the focus of a convex lens, its virtual, straight, and a large image is made towards the object, here the convex lens acts like a magnifier.
- Combined Microscopes: The combination of two lenses to achieve magnification, whereby superfluous particles are seen clearly, is called a combined microscope.
History of microscopes
The history of the microscope is about 400 years old, it was discovered in Netherland. The laws of reflection, refraction and linear transmission of light were known to Greek philosophers a few centuries before Christ, but the Sine’s law of incidence angle and angle of refraction was not invented until the late 17th century.
Snell of Holland and Dekart of France (1551–1650 AD) invented it differently. Alhazen, the Arabian astrologer of about 1000 CE, formulated the laws of reflection and refraction, but they were not in sine but in the perpendicular distance.
It is said that he had a large lens. The microscope starts from here. The creation of the microscope is attributed to Zecharios Jonemides, a botanist. According to Heinz, the invention is attributed to Cornelius Drabble.
