SIMPLE
MICROSCOPE
A simple microscope is a
type of microscope that
uses a single lens to
magnify the object. A
simple microscope is
made out of a convex lens
with a short focal length.
COMPOUND
MICROSCOPE
A compound microscope
is a type of microscope
with more than one lens. It
is made up of lenses as
well as two optical
elements known as an
objective lens and an
eyepiece or ocular lens.
ELECTRON
MICROSCOPE
An electron microscope is a
type of microscope in which
the source of illumination is an
accelerated electron beam. It
is a type of microscope with
great image resolution since
the images can be amplified
in nanometers.
STEREO MICROSCOPE
A stereo microscope is a type of
microscope that allows you to see a
specimen in three dimensions.
A dissecting microscope is another
name for it.
A stereo microscope has distinct
objective lenses and eyepieces,
resulting in two different optical
channels for each eye.
SCANNING PROBE
MICROSCOPE
The scanning probe microscope is a
type of microscope that finds uses in
industries where specimens are
examined at nanoscale levels.
A scanning probe microscope can be
used to investigate a specimen's
characteristics, reaction time, and
behavior when stimulated.

There are 5 different types of microscopes and each of
these has different purposes of use. These five types of

WHAT MICROSCOPES CAN DO?
What Are The Different Types Of
Microscope?
The magnification capability of microscopes allows us to view
numerous things that are too small to see with our naked eyes.
Microscopes are mostly used in scientific study. In truth,
microscopes are capable of much more. Here are a couple such
examples:
Microbiology - Microscopes enable us to see things we couldn't
previously. In the late 1600s, Antonie van Leeuwenhoek
performed just this to make the first observations of bacteria
and protozoa. We can discover microorganisms that cause
diseases using microscopy and specific stain techniques such as
Gram stains.
Cell Biology- Microscopy is the primary instrument used to
explore how organelles and the cytoskeleton function in cells.
Many studies shed light on the mechanisms of disease.
Human Physiology and Medicine - Histological examination of
tissue organ slices and blood smears aids in the diagnosis of
numerous disorders.
Reproductive medicine - In vitro fertilization (IVF) is impossible
without accurate injection under the microscope.
Forensic Science- Microscopes are commonly employed in
forensic science to identify small criminal evidence such as
hairs.
Environmental monitoring - Several critical planktons, such as
algae, euglena, and rotifers, are important indicators that can be
observed under a field microscope to monitor the aquatic
ecosystem.

Agriculture - A microscope can help with soil validation and
insect management, among other things.
Art and jewelry appraisal - Portable microscopes are necessary
equipment for determining the worth of artworks.
Metallurgy and Manufacturing - Metallographic microscopes are
used to detect flaws in metal surfaces, assess the quality of
metal alloys, and investigate rocks, ceramics, and minerals.
Microscopy is used to uncover small evidence in flight crashes
caused by metal fatigue.
Semiconductor- Microscopes are significantly used in
microelectronics and semiconductor manufacturing to provide
quality control.
NanotechnologyWithout
electron
microscopes,
the
development of nanomaterials such as carbon nanotubes and
graphene would be impossible.

An Overview of
Microscopes
What is a microscope? A laboratory
equipment called a Miscroscope is used to
see things that are too small to be seen
with the naked eye. In science labs and
schools, microscopes are frequently used to
view a variety of tiny objects, including
cells, bacteria, tissue structures, materials
and electronics. Magnification (enlarging
the image) and contrast are provided by
microscopes (making them stand out of the
background). To do this, microscopes are
composed of a few magnification lenses,
each with a different level of magnification
and focusing power.

History of Microscope
FIRST SIMPLE MICROSCOPES (OR MAGNIFYING GLASSES)
Simple microscopes or magnifying glasses with only one convex lens
were first used in the 13th century, according to historical records.
Italians started wearing lenses in their spectacles at that time, which
may have contributed to the widespread use of inexpensive
microscopes. These single-lens magnifying glasses, however, only
possessed a very little magnification.
VAN LEEUWENHOEK’S MICROSCOPES
Antonie Van Leeuwenhoek (1632-1723) was
a Dutch businessman and scientist. He is
often regarded as "The Father of
Microbiology" and was among the first
microscopists and microbiologists. He also
built at least 25 different varieties of
single-lens microscopes. Leeuwenhoek
updated his microscopes so that they could
magnify up to 275 times. Leeuwenhoek
reported the first finding of protists (named
infusoria) in 1674 and bacteria (called
"small animals" or animalcules) in 1783
using his microscopes. He also noticed the
vacuole inside the cells, sperm motility, and
the banded pattern on muscle fibers.

FIGURE 1
The name “microscope” came from two
words – “micro” and “scope”. “Micro” means
small or tiny. “Scope” means to view or to
observe. Therefore, a microscope can be
understood as an instrument to see tiny things.

FIRST COMPOUND MICROSCOPES
Although various claims have been made
throughout the years, the true inventor of
the compound microscope is unknown.
Among these claims is that Zacharias
Janssen invented the first compound
microscope in the early 1600s. Janssen's
compound microscope was made up of
two convex lenses that were aligned in
series: an object-glass (objective) that
was closer to the object or specimen, and
an eyepiece (ocular) that was closer to
the observer's eye.
