Synonyms Histology; Histopathology; Optical microscopy Description The light microscope, recognized as one of man's greatest inventions, is the gold standard for diagnosing cancer and other diseases. Even in this "molecular age," tumor treatment is rarely undertaken without a "tissue diagnosis." ...
History of the Microscope During that historic period known as the Renaissance, after the "dark" Middle Ages, there occurred the inventions of printing, gunpowder and the mariner's compass, followed by the discovery of America. Equally remarkable was the invention of the light microscope: an ...
A light microscope, even one with perfect lenses and perfect illumination, simply cannot be used to distinguish objects that are smaller than half the wavelength of light. White light has an average wavelength of 0.55 micrometers, half of which is 0.275 micrometers. (One micrometer is a ...
摘要: The purpose of this work is to probe deeply enough to define the microelectronic technology and, having done so, to try to identify its beginnings and trace its developments by marking the major events in easily understandable chronological sequence....
The first electron microscope was developed in the 1930’s by Max Knoll and Ernst Ruska. Electron microscopes can provide pictures of the smallest particles but they cannot be used to study living things. Its magnification and resolution is unmatched by a light microscope. ...

found a way to achieve a resolution greater than that of light. They stopped using light, instead realizing they could transmit electrons through a specimen to form an image. This discovery led to the first transmission electron microscope (TEM), where the electrons are pointed directly at the ...
In 1665, Robert Hooker published the book "Microscope," in which he coined the term "cell." Robert Hook had a major argument with Newton, the great scientific master of the day, about the nature of light. Light, according to Newton, is a particle, while according to Robert, it is a ...
