All about Microscopes . Microscopes can be defined as instruments which are used to see a small object or particals by magnifying it. There are many types including optical, electron and x-ray. The most common type is the optical version which forms images from visible light by using lenses.
The most common microscope (and the first to be invented) is the optical microscope, which uses light to pass through a sample to produce an image. Other major types of microscopes are the fluorescence microscope, the electron microscope (both the transmission electron microscope and the scanning electron microscope
All the microscopes described so far produce black and white images. To observe color in cells, scientists use polarizing microscopes. The microscope aligns the vibrations of a light wave by directing it through a specially cut prism. If two beams of polarized light are transmitted through the cell, as in a differential polarization microscope ...
Molecular Expressions: Images from the Microscope The Molecular Expressions Website features hundreds of photomicrographs photographs through the microscope of everything from superconductors and high-tech materials to ice cream and beer.
5 Things You Should Know About Microscopes. The magnification power of a light microscope is achieved by multiplying the power of the eyepieces by the power of the respective objective lens. There are two broad categories of light microscope: Stereo and Compound. Stereo are Low Power or Dissecting microscopes.

Interesting Microscope Facts. 1. As is the case with many other technological devices, microscopes have a very long history. By the 1st century, glass had been invented and the Romans had started experimenting with different sizes and shapes to observe objects.
In this lesson, you'll learn about the history and key parts of an essential scientific tool: the microscope. Microscopes have been around for centuries, but they continue to be updated, allowing ...
Microscope: Microscope, instrument that produces enlarged images of small objects, allowing the observer an exceedingly close view of minute structures at a scale convenient for examination and analysis. It may provide a dynamic image (as with optical instruments) or one that is static (as with scanning electron microscopes).
