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.
Compound microscopes first appeared in Europe around 1620. [2] [3] The actual inventor of the compound microscope is unknown although many claims have been made over the years. These include a dubious claim that Dutch spectacle-maker Zacharias Janssen invented the compound microscope and the telescope as early as 1590.
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 ...

The company of Carl Zeiss exploited this discovery and becomes the dominant microscope manufacturer of its era. 1928: Edward Hutchinson Synge publishes theory underlying the near-field scanning optical microscope; 1931: Max Knoll and Ernst Ruska start to build the first electron microscope. It is a transmission electron microscope (TEM).
The Campani compound microscope is a microscope on exhibit at the Museo Galileo in Italy, thought to have been built by optical instrument maker Giuseppe Campani in the second half 17th century. For a time it was thought to have been built by Italian scientist Galileo Galilei but no longer bares that attribution.
5. The rays travel through the objective lens and are focused for the second Nomarski-modified Wollaston prism. 6. The second prism recombines the two rays into one polarised at 135°. The combination of the rays leads to interference, brightening or darkening the image at that point according to the optical path difference.
Biological systems exist as a complex interplay of countless cellular components interacting across four dimensions to produce the phenomenon called life. While it is common to reduce living organisms to non-living samples to accommodate traditional static imaging tools, the further the sample deviates from the native conditions, the more likely the delicate processes in question will exhibit ...
