A microscope is an an optical
instrument used for viewing very
small objects,
such as mineral samples or animal or
plant cells, typically magnified several
hundred times.

During the 1st century AD (year
100), glass had been invented by
the Romans.

5. Once the glass had been invented, the Romans
started experimenting with it and testing it.
They found that if the glass is thick in the middle and
thin on the edges and If we hold one of these
“lenses” over an object, the object would look larger.

6. During the 1590s, two Dutch spectacle
producers further experimented with these
early lenses.
Zaccharias Janssen and his father Hans
started experimenting with these lenses.
They had invented the compound
microscope (which is a microscope that uses
two or more lenses), but they could achieve
a magnification of 9x only.

HISTORY OF MICROSCOPE
In the late 17th Century, Anthony von
Leeuwenhoek from Holland invented a single
lens, hand-held microscope that could achieve a
magnification of 270x.

10. STEREO MICROSCOPE
STEREO MICROSCOPE
A stereo microscope is used for
low-magnification applications
and for 3D observation of
subjects that are normally visible
to the naked eye.
12. INVERTED MICROSCOPE
INVERTED MICROSCOPE
An inverted microscope is a
microscope with its light source
and condenser on the top, It was
invented in 1850 by J. Lawrence
Smith, a faculty member of
Tulane University
14. POLARIZING MICROSCOPE
POLARIZING MICROSCOPE
The polarizing microscope is
particularly useful in the study of
birefringent materials such as
crystals and strained non-
crystalline substances. It is widely
used for chemical microscopy and
optical mineralogy.
