The Microscope
Summary
Ever wondered how “magnification” was
born? Well, in this presentation one can see
who exactly invented the microscope, how it
works, and when the magnificent tool came
about.
Founders of The
Microscope
Antony Van
Leeuwenhoek was the
first man to make and
use a real microscope.
Digges of England and
Hans and Zcharias
Janssen of Holland were
the first pioneers in the
history of the
microscope.
What? When? How?
The light microscope
Discovered in 1674
Leeuwenhoek was working one day as
a glass grounder and he found out that
by placing glass lenses at certain
distances he could enlarge objects.
Using a Microscope
First a slide containing an
organism is placed on the
stage.
According to the size of the
organism, select the proper
objective lens.
Place the eye over the
eyepiece.
Later, commence focusing
with the coarse focus, then
the fine focus until you are
able to see the organism
properly.
Comments
Many objects too small to be seen with
the unaided eye can be viewed through
a microscope. The development of the
microscope greatly affected human life.
Before it was invented, little was known
about tiny creatures, bacteria, and
viruses. Today the microscope is widely
used by a variety of scientists around
the world.
