Microscopes are important tools. But do you know the difference between there microscopes and when to use each type? The compound light microscope combines the power of lenses and light to enlarge the subject being viewed.

The stereo microscope allows an object to be viewed three-dimensionally under the lenses.

Very small, live cells, like bacterial cells should be viewed using a scanning electron microscope.

The scanning electro microscope produces high-resolution, sharp, black and white 3D images.

If your task was to dissect the mouth parts of a grasshopper, you would use a compound light microscope to assist you.

Electron microscopes differ from light microscopes in that they produce an image of a specimen by using a beam of electrons rather than a beam of light.

The light compound microscope is composed by two groups of lenses. In the first one, the lens projects a real intermediate image which is enlarged and inverted to the focal plane of the eyepiece. In the second group, the eyepiece that behaves like a magnifying glass, gives an image of the intermediate image which is enlarged and inverted again.

The transmission electron microscope is an electron microscope for viewing objects much smaller than cells.

The transmission electron microscope (TEM or TEM) uses a high-voltage electron beam emitted by an electron gun.

If sample preparation is longer and more demanding than for optical microscopy, the resolution offers an incomparable view of the structures. Transmission electron microscopy allows to visualize intracellular organelles, viruses, crystals ...

A microscope that has lower magnifying power ==> Stereoscope (dissecting microscope).

The stereomicroscope is a special type of magnifying glass, often called a binocular loupe.

It is a device intended primarily for observation at low magnification with lighting overhead. It allows especially stereoscopic perception, in relief, of small subjects.

The stereomicroscope should not be confused with a microscope equipped with a binocular head. The latter only provides two identical images, with a "flat" rendering.

A microscope which magnifies from magnification ranging from 20X to 30.000X... ==> Scanning electron microscope

Scanning electron microscopy (SEM) is an electron microscopy technique capable of producing high resolution images of the surface of a sample using the principle of electron-matter interactions.

This microscope consists of an electron beam scanning the surface of the sample to be analyzed which, in response, reemits certain particles. These particles are analyzed by different detectors that reconstruct a three-dimensional image of the surface.

Explanation:

thermophiles, notice the prefix thermo.

lizards have adapted to life in the desert. some desert lizards have toes with spiny scales to them run across the sand without sinking. some use the sand to hide from predators, or to search for small animals that they prey upon.
