Microscope
was discovered during the historic period known
as the Renaissance, after the "dark"
middle Ages. Microscope is an instrument that
enables the human eye, by means of a lens or
combinations of lenses, to see expanded images
of very tiny objects that cannot be seen with
naked eyes.
Microscope was
invented someone picked up a piece of transparent
crystal thicker in the middle than at the edges,
looked through it, and discovered that it made
things look larger.
Development
of microscope went through many stages the first
microscope was a tube with a plate for the object
at one end and, at the other, a lens which gave
a magnification less than ten diameters -- ten
times the actual size. In 1609, Galileo, worked
out the principles of lenses, and made a much
better instrument with a focusing device.
Then Anton van
Leeuwenhoek of Holland (1632-1723) recognized
that it can see and describe bacteria, yeast
plants, the teeming life in a drop of water,
and the circulation of blood corpuscles in capillaries.
After this many improvement were made then several
European countries began to manufacture fine
optical equipment Present day instruments, changed
but little, give magnifications up to 1250 diameters
with ordinary light and up to 5000 with blue
light.
Then the introduction
of today’s microscope happened, it was
an electron microscope If pushed to the limit,
electron microscopes can make it possible to
view objects as small as the diameter of an
atom.
This is the
history of microscopes in brief.
