The light-warping structures known as metamaterials have a new trick in their ever-expanding repertoire. Researchers at the National Institute of Standards and Technology (NIST) have built a silver, glass and chromium nanostructure that can all but stop visible light cold in one direction while giving it a pass in the other.
First-day attendees at SPIE Photonics West heard talks on new developments for imaging the brain at the cellular level, technologies to bring healthcare to remote, under-served areas of the world, and more, as the week-long event opened at Moscone Center in San Francisco Saturday.
Broadband Transformational Optics Lens, Described in Applied Physics Letters, May Lead to Antenna Dishes that are Flat or Conform to Any Surface
No one has ever been so close to the ideal laser. In theory, a laser has exactly one color (frequency or wavelength). In reality, however, there is always a certain line width. The laser, the researcher of the Physikalisch-Technische Bundesanstalt (PTB) has now developed together with US researchers from the JILA, a joint institute of the American National Institute of Standards and Technology (NIST) and the University of Boulder, Colorado Of only 10 mHz a new world record.
Multiphoton confocal microscopes from Carl Zeiss now permit the simultaneous use of two NLO lasers or one laser with an optical parametric oscillator (OPO). Both components are fully integrated and expand the functionality of the multiphoton systems.
Newport Corporation, a worldwide leader in photonics solutions, is introducing convenient spherical lens kits for popular plano-convex or bi-convex lenses.
A new series of Sapphire™ lasers from Coherent, Inc. (Santa Clara, CA) (Nasdaq: COHR) offer orange output, which is particularly well matched for exciting a number of fluorescent dyes used in bioimaging. Specifically, the new Sapphire models deliver 20 mW, 50 mW, 75 mW or 100 mW at 588 nm.
