Light microscopes become a very powerful tool Today, the family of microscopes was significantly expanded.Microscopes had become an essential instrument in modem technology, research, and industry.In the family
In 1611, Johannes Kepler discovered total internal reflection and described the small angle approximation to the law of refraction. In 1621, Willebrord Snell made a major discovery: the law of refraction; the formulation of this law in terms of sines was later published by Ren´e ...

Physics dictates light microscopes are limited to magnification of 500x to 1000x and a resolution of 0.2 micrometers (2,000 angstroms). Four years later, Carl Zeiss overcame this limitation and introduced the first commercial UV microscope, which had resolution twice as powerful as a visible ...

In the Netherlands, around 1590, Hans Janssen and his son invented a compound microscope—constructed of two convex lenses. In the early 1600s (about 1610), the great Galileo Galilei (1564–1642) constructed several simple microscopes and telescopes, which he called as “occhialino.” The term...
discovery of factual entities. This paper examines historical and philosophical aspects of the experimental discovery by Carl Woese of archaea, prokaryotes that comprise one of the three principal domains of the phylogenetic tree. Borrowing Kuhn’s terminology, this discovery of a major biological ...
Although often amusing to many modern biologists, serious scientific debate surrounded preformationism until the late 1700s.Peering through early light microscopes, some naturalists believed they could see entire miniature humans elegantly packaged into sperm and eggs. According to theory, once fertilized...
cameras. It is ideal for visual inspections of semiconductor wafers and electronics components, and can detect microscopic scratches and surface irregularities, which are difficult to confirm with the naked eye. It can also identify materials that are difficult to distinguish under visible light. ...
