Photomicrograph
Photomicrograph
A Photomicrograph (/ˌfoʊtoʊˈmaɪkrəˌɡræf/; from the Greek words for "light" and "small," and "to write") is a photograph or digital image taken through a microscope or similar device to show a magnified image of an item not visible to the naked eye.
Etymology
The term "Photomicrograph" is derived from three Greek words: "photos" (light), "mikros" (small), and "graphé" (to write). It was first used in the late 19th century to describe the process of using light to magnify small objects and capture their images on film.
Usage
Photomicrographs are used extensively in microbiology, metallurgy, chemistry, and biology for studying the detailed structure of biological or inorganic specimens. They are also used in the forensic science field for identifying minute evidence such as fibers, hair, and other trace materials.
