Antonie van Leeuwenhoek (1632–1723). The field of microscopy (optical microscopy) dates back to at least the 17th-century.Earlier microscopes, single lens magnifying glasses with limited magnification, date at least as far back as the wide spread use of lenses in eyeglasses in the 13th century [2] but more advanced compound microscopes first appeared in Europe around 1620 [3] [4] The ...
A microscope is an instrument used to see objects that are too small to be seen by the naked eye. Types of microscope include: Optical microscope; Stereo microscope; Digital microscope. USB microscope; Electron microscope. Scanning electron microscope; Microscope may also refer to:
Subsequently, the word was used in Frank Scully's puzzle book Bedside Manna, after which time, members of the N.P.L. campaigned to include the word in major dictionaries. [9] [10] This 45-letter word, referred to as "p45", [11] first appeared in the 1939 supplement to the Merriam-Webster New International Dictionary, Second Edition. [12]
An unpaired word is one that, according to the usual rules of the language, would appear to have a related word but does not. [1] Such words usually have a prefix or suffix that would imply that there is an antonym , with the prefix or suffix being absent or opposite.
The optical microscope, also referred to as a light microscope, is a type of microscope that commonly uses visible light and a system of lenses to generate magnified images of small objects. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century.
A comparison microscope is a device used to analyze side-by-side specimens. It consists of two microscopes connected by an optical bridge, which results in a split view window enabling two separate objects to be viewed simultaneously. This avoids the observer having to rely on memory when comparing two objects under a conventional microscope.

The stereo, stereoscopic or dissecting microscope is an optical microscope variant designed for low magnification observation of a sample, typically using light reflected from the surface of an object rather than transmitted through it. The instrument uses two separate optical paths with two objectives and eyepieces to provide slightly ...
