What does microscopy mean?
Microscopy is the use of a microscope to examine objects, tissues, cells, microorganisms, or other features that are too small to be seen clearly with the unaided eye. In a scientific context, the word can refer either to the practical technique—using different kinds of microscopes to observe specimens—or to the wider field of study that develops and applies microscopic methods. Light microscopy uses visible light and lenses, while electron microscopy uses a beam of electrons to achieve much greater magnification. The term is common in medicine, biology, chemistry, materials science, and geology. It is also used more broadly to describe careful investigation of minute details. Related words include microscope, the instrument used for observation; microscopic, meaning too small to be seen clearly or involving minute detail; and microscopist, a specialist who studies or uses microscopic techniques.
nounThe technique or practice of examining objects or specimens using a microscope, especially objects too small to be seen clearly with the naked eye. It can also refer to the scientific study of microscopic structures and organisms.
- The technique or practice of examining specimens using a microscope.
- The scientific study of objects and organisms too small to be observed directly with the naked eye.
"The sample was examined under high-power microscopy to identify the cause of the contamination."
"The new microscope enabled researchers to study the cells in greater detail."
"Her lecture in medical microscopy explained how clinicians identify disease-causing organisms."
Usually used as an uncountable noun; the plural is rare and may refer to separate microscopic examinations.
"The research involved several detailed microscopies of the preserved specimens."
Microscopy turns the invisible into a world of cells, crystals, and microorganisms—all revealed by enlarging what the naked eye cannot see.

Where does microscopy come from?
Microscopy was formed in the 19th century from the combining form micro-, meaning small, and the Greek-derived suffix -scopy, meaning examination or observation. The related word microscope combines micro- with the Greek skopos, meaning watcher or observer. The same roots also underlie microscopic, microcosm, and microorganism, all of which refer broadly to small things or the observation of small things.

How microscopy is actually used
The term is used in scientific, medical, and technical contexts. In general use, it often means the process of examining something with a microscope; in academic writing, it may refer more broadly to the field of microscopic investigation.
Easily confused with microscopy
A microscope is the instrument used to view tiny specimens, whereas microscopy is the technique or scientific practice of examining them.
