Electron Microscope

Charmain McNulty

An electron microscope has many uses today, mainly to do with scientific study. The electron microscope has been developed to look at the tiniest structures, arrangements and components; it can magnify an object two million times.

It works by using electrons instead of light. The electrons can fit through smaller gaps in specimens creating a clearer magnified image. There are two types of electron microscope, a scanning electron microscope and a transmission electron microscope. A SEM creates a magnified image of the surface of an object, and a TEM produces a magnified image of a specimen.

biopsies, to find diseases such as cancer. And as the electron microscope has improved, so has the health of the world’s population with diseases being diagnosed faster and more medicines and cures being made. Immunology and virology are other sciences linked with this.

Cytology, study of cells and their components uses the electron microscope to see entire structures or systems. Great developments, in this field, have been made due to the electron microscope. Morphology is similar to this study also.

Another science, genetics, has made great leaps and bounds in its findings thanks to the electron microscope. Diseases can now be

, has been aided with the electron microscope by botanists being able to find out more about ecology and therefore helping improve agriculture and horticulture.

Along with the above, the electron microscope is used in the study of many elements, for example crystallography, metallography and metallurgy.

The study of crystals looks at the actual arrangements of atoms in crystals, which in turn looks at the arrangement of atoms and molecules in many more substances and elements.

Metallography looks at the crystalline structure of metals and their alloys. This links to metallurgy, the science and art of adapting and processing metals to satisfy human demand. With the electron microscope, it can see defects caused and therefore repair and restore them to be the best for human consumption.

    The history, development and use of the light and electron microscope

    3 star(s)

    This is because Electron Microscope uses beam of electrons to focus the specimen rather that focusing light, this illuminates the specimen. Electron microscope has given us a great understanding of cellular structure because it provides us with great images which can be seen clearly compared to light microscope.

  2. Optical and Electron Microscopy

    Varying the current passing through this magnetic coil focuses the specimen. The final magnetic coils, also known as the projector lenses, enlarge the image, projecting it onto a fluorescent screen so that the human eye, which is insensitive to electrons, can see the image, as the fluorescent screen is sensitive to electrons.
