Gravitational Lensing
A gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer that is capable of bending the light from the source as the light travels toward the observer. This effect is known as gravitational lensing, and the amount of bending is one of the predictions of Albert Einstein's general theory of relativity. Treating light as corpuscles travelling at the speed of light, Newtonian physics also predicts the bending of light, but only half of that predicted by general relativity. Although Einstein made unpublished calculations on the subject in 1912, Orest Khvolson (1924) and Frantisek Link (1936) are generally credited with being the first to discuss the effect in print. However, this effect is more commonly associated with Einstein, who published an article on the subject in 1936. Fritz Zwicky posited in 1937 that the effect could allow galaxy clusters to act as gravitational lenses. It was not until 1979 that thi ...

Wilhelmina Elisabeth Lensing
Wilhelmina Drucker (née ''Wilhelmina Elizabeth Lensing''; Amsterdam, 30 September 1847 – Amsterdam, 5 December 1925) was a Dutch politician and writer. One of the first Dutch feminists, she was also known under her pseudonyms Gipsy, Gitano, and E. Prezcier. Life Drucker was one of two daughters born to the seamstress Constantia Christina Lensing and the German-Jewish banker Louis Drucker. Her father refused to marry her mother or to legally recognise their children, meaning Wilhelmina grew up in difficult circumstances. She received a Catholic education took up the same profession as her mother and from 1886 onwards attended meetings of the Sociaal-Democratische Bond, the De Unie union, the Nederlandsche Bond voor Algemeen Kies- en Stemrecht (Dutch League for General Suffrage) and the freethinkers' association De Dageraad. In the following years socialism had a major formative influence on her. She argued from her personal experience against a wider background, analysing and u ...

Lens (optics)
A lens is a transmissive optical device which focuses or disperses a light beam by means of refraction. A simple lens consists of a single piece of transparent material, while a compound lens consists of several simple lenses (''elements''), usually arranged along a common axis. Lenses are made from materials such as glass or plastic, and are ground and polished or molded to a desired shape. A lens can focus light to form an image, unlike a prism, which refracts light without focusing. Devices that similarly focus or disperse waves and radiation other than visible light are also called lenses, such as microwave lenses, electron lenses, acoustic lenses, or explosive lenses. Lenses are used in various imaging devices like telescopes, binoculars and cameras. They are also used as visual aids in glasses to correct defects of vision such as myopia and hypermetropia. History The word '' lens'' comes from '' lēns'', the Latin name of the lentil (a seed of a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Thermal Lensing
Thermal blooming, also known as thermal lensing, is an atmospheric effect, seen in high energy laser beams; It is the result of the nonlinear interaction of laser radiation with the propagation medium (e.g. air or glass), which is heated by the absorption of a fraction of the radiation, causing a "thermal lens" to form, with a dioptric power related to the intensity of the laser, among other factors. The amount of energy absorbed is a function of the laser wavelength In physics, the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats. It is the distance between consecutive corresponding points of the same phase on the wave, such as two adjacent crests, tr .... The term "thermal blooming" is often used to describe any type of self-induced "thermal distortion" of laser radiation.
