Zacharias Janssen; also Zacharias Jansen or Sacharias Jansen; 1585 – pre-1632 [1]) was a Dutch spectacle-maker who lived most of his life in Middelburg.He is associated with the invention of the first optical telescope and/or the first truly compound microscope, but these claims (made 20 years after his death) may be fabrications put forward by his son.
In the 1670s, he started to explore microbial life with his microscope. Using single-lensed microscopes of his own design and make, Van Leeuwenhoek was the first to observe and to experiment with microbes, which he originally referred to as dierkens, diertgens or diertjes. [note 3] He was the first to relatively determine their size.
Optical microscope – Microscope that uses visible light; Reticle – Aim markings in optical devices, e.g. crosshairs; Sash window – Window made of one or more movable panels; Savart wheel – Acoustical device to generate a pitch; Shadowgraph – Optical method to reveal non-uniformity; Universal joint – Mechanism with bendable rotation axis
Scientist using an optical microscope in a laboratory. 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 ...
Heisenberg's microscope is a thought experiment proposed by Werner Heisenberg that has served as the nucleus of some commonly held ideas about quantum mechanics. In particular, it provides an argument for the uncertainty principle on the basis of the principles of classical optics .
1957: Marvin Minsky, a professor at MIT, invents the confocal microscope, an optical imaging technique for increasing optical resolution and contrast of a micrograph by means of using a spatial pinhole to block out-of-focus light in image formation. This technology is a predecessor to today's widely used confocal laser scanning microscope.
Scientists have used a food coloring dye used in Doritos and other products to create mice with see-through skin, a low-cost way to assess the body's internal operations.
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 ...
