Electron Microscope Offers Detailed Specimen Information
By Cedric B Georges
An electron microscope offers many things that other
microscopes do not. For example, items that are placed
on a microscope slide for electron microscopes are able
to be seen with an amazing depth of field, since they
can be magnified up to two million times their normal
size.
These are things that cannot be seen with a light microscope.
Electron microscopes come in a variety of types that
anyone can use if they are looking for a special type
of microscope.
Three Types Of Electron Microscope
Three types of electron microscopes exist. They are
the transmission electron microscope, the scanning electron
microscope, and the scanning-tunneling electron microscope.
The original of all of these types of microscopes is
the transmission electron.
The TEM, as it is commonly called, transmits electrons
through a small slice of a specimen in order for the
image to be seen. These types of microscopes are great
for seeing inside the cells of beings on the planet.
Much has been learned by using these microscopes for
seeing all types of various cells.
The Greater Depth Of Field With Scanning Microscopes
The other electron microscope types that are used are
the scanning electron microscopes and the scanning tunneling
microscope. The SEMs, or the scanning microscopes, have
a greater depth of field because of the difference of
how they work.
Because the specimens are covered with atoms, when
the electron beam is scanned over the item to be looked
at, the electrons on the surface become excited and
thus an image is created. These images can be 3-d and
can allow a person to see the image in depth.
The scanning tunneling microscope or STM, can show
the tiniest of atoms on a surface because the electrons
actually jump between the tip of the microscope and
the specimen. This tunneling current will then create
an image. These images are also very in depth and can
allow a scientist to see atoms that previously could
not be viewed.
Specimens Can Be Viewed In Three Dimensions
Various types of the electron microscope are available
for people to view specimens. These types of microscopes
are great to view items, such as cells that people once
thought would never be seen by humans.
Thanks to great technology, these specimens can be
viewed in three dimensions, which can offer people more
wiggle room in order to study and learn the in’s and
outs of these specimens. Making strides in helping people
has never been more simple thanks to the invention of
the many types of the electron microscope that are on
the market today.

More Microscope Facts....
If you have ever had a science class in the course
of your education then you know how important microscopes
are to the world. It helps us identify subatomic particles,
cells and even helps create electronic components.
There is a plethora of websites on the internet that
can direct you towards where you need to go in order
to purchase a microscope for your own personal use or
for laboratory use. All you have to do is know where
to look. That part is made simple for you.
