Leeuwenhoek microscope

Leeuwenhoek microscopeSince ancient times people were dividing the Universe into macro- and microcosm.Macrocosm is the world of large bodies, stars, and planets.Microcosm is the world of elements of which everything animate and inanimate consists. Macrocosm objects can be seen by merely raising your head to the sky, or not raising it at all.But how can one see the objects of microcosm? The first optical device for examining small objects with great magnifying power was created in the Netherlands by optician Jansen in 1590.The microcosm turned out to be so attractive that Galileo himself was captured by it. He used his telescope as a microscope although it was very uncomfortable for such examinations as it had big sizes and low magnifying power.But real creation of a microscope is usually associated with the name of Dutch scientist Antonie van Leeuwenhoek who lived in 1632-1723. There was a “classic” microscope in the shape of a compact spyglass but Leeuwenhoek designed a single-lens microscope. Its design is very simple but at the same time very efficient.Leeuwenhoek microscope is a metal plate with a small orifice in the middle. A bead-lens is inserted into this orifice. Due to high-quality glass processing Leeuwenhoek managed to achieve a great magnifying capacity – up to 150 times. Leeuwenhoek later enhanced his design by doubling magnifying capacity up to 300 times. Leeuwenhoek microscope was the device which started actual scientific microscopy.
