- STED Microscope Inventor to Receive Springer Prize
This year’s recipient of the Julius Springer Prize for Applied Physics is Göttingen, Germany-based researcher Stefan W. Hell for his revolutionary discovery that resolutions far below the diffraction limit can be achieved in a fluorescence microscope using conventionally focused light, Springer announced. The STED (stimulated emission depletion) microscope Hell invented is the first optical microscope to show details at the nanoscale, in resolutions far below the light wavelength using conventional lenses. This technique opens up new possibilities in the life sciences because it allows noninvasive imaging of the inside of cells. Hell has been a researcher at the Max Planck Institute for Biophysical Chemistry since 1997. He is a scientific member of the Max Planck Society, adjunct professor of physics at the University of Heidelberg, honorary professor of experimental physics at the University of Göttingen and a member of the Göttingen Academy of Sciences. He has received numerous research prizes, including the Prize of the International Commission for Optics (2000), the Carl Zeiss Research Award (2002) and last year's German Innovation Award. The Springer Prize is awarded by the editors-in-chief of the Springer journals Applied Physics A-Materials Science & Processing and Applied Physics B-Lasers and Optics. Hell will receive the prize and $5000 during a plenary session at LASER.World of Photonics 2007 in Munich on June 19.
- The emission of light or other electromagnetic radiation of longer wavelengths by a substance as a result of the absorption of some other radiation of shorter wavelengths, provided the emission continues only as long as the stimulus producing it is maintained. In other words, fluorescence is the luminescence that persists for less than about 10-8 s after excitation.
- An instrument consisting essentially of a tube 160 mm long, with an objective lens at the distant end and an eyepiece at the near end. The objective forms a real aerial image of the object in the focal plane of the eyepiece where it is observed by the eye. The overall magnifying power is equal to the linear magnification of the objective multiplied by the magnifying power of the eyepiece. The eyepiece can be replaced by a film to photograph the primary image, or a positive or negative relay...
- Pertaining to optics and the phenomena of light.
- The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
- 1. In optics, the ability of a lens system to reproduce the points, lines and surfaces in an object as separate entities in the image. 2. The minimum adjustment increment effectively achievable by a positioning mechanism. 3. In image processing, the accuracy with which brightness, spatial parameters and frame rate are divided into discrete levels.
