Microscopy (mi-kros-kuh-pee)

Microscopy is the technical field of using microscopes to view objects and areas of objects that cannot be seen with the naked eye.

Etymology

The term "Microscopy" comes from the Greek words mikros meaning "small" and skopein meaning "to look or see".

History

Microscopy has been a fundamental tool in many scientific disciplines, especially in biology and medicine. It was first developed in the 17th century by Antonie van Leeuwenhoek and Robert Hooke.

Types of Microscopy

There are several types of microscopy techniques, each used for different purposes. These include:

  • Light Microscopy: This is the oldest form of microscopy, where light is passed through a specimen and then through glass lenses to produce a magnified image.
  • Electron Microscopy: This type of microscopy uses a beam of electrons instead of light to create an image of the specimen. It has a much higher resolution than light microscopy.
  • Scanning Probe Microscopy: This form of microscopy measures the interaction between a probe and a specimen surface to form an image.
  • Fluorescence Microscopy: This technique uses fluorescence and phosphorescence instead of, or in addition to, reflection and absorption to study properties of organic or inorganic substances.

Related Terms

  • Microscope: An instrument used to see objects that are too small to be seen by the naked eye.
  • Magnification: The process of enlarging the appearance, not physical size, of something.
  • Resolution (microscopy): The smallest distance between two points on a specimen that can still be distinguished as two separate entities.
  • Specimen: An individual object or organism being examined under the microscope.
  • Slide: A small flat rectangular piece of glass on which specimens can be mounted for microscopic study.
