Raman Scattering Sped Up for Microscopy
GARCHING, Germany, Oct. 18, 2013 — Improvements to Raman spectroscopy using laser frequency combs allow multiple signals from different parts of a molecule — or even different molecules — to be monitored simultaneously using a single detector. The advance is seen as a major step toward the holy grail of real-time, label-free biomolecular imaging. For decades, biologists have attached fluorescent dye labels to certain proteins to distinguish them under a microscope. But such labels can alter the cell’s...
Spinning-disk Microscope Peers into the Heart of a Cell
LONDON, Oct. 10, 2013 — A new microscopy technique with unprecedented focusing ability will allow structures deep within cells, including viruses and bacteria, to be investigated for the first time.
Judges Named for Olympus BioScapes Competition
CENTER VALLEY, Pa., Oct. 8, 2013 — Four widely respected researchers in the fields of microscopy and imaging have joined the judging panel for the 10th annual BioScapes International Digital Imaging Competition, Olympus announced last week. A panel including James E. Bear, Ph.D., of...
Seeing Cells Through Silicon
ARLINGTON, Texas, & CAMBRIDGE, Mass., Oct. 4, 2013 — A new type of near-infrared microscopy can image cells through a silicon wafer, providing more information about diseased or infected cells flowing through microfluidic devices. “This has the potential to merge research in cellular...

GDD Measurements Boost Ultrafast Laser Performance
Oct 1, 2013 — Easy group delay dispersion measurements improve results in applications such as laser amplifiers, optical coatings, harmonic generation, bioimaging and microscopy. “Dude, where’s my pulse width?!” Anybody working with an ultrafast...
Photonics firm a finalist in Nokia sensing contest
Oct 1, 2013 — A firm founded by University of California, Los Angeles, professor Aydogan Ozcan and his students has made it to the final round of a $2.25 million international competition for companies improving health care by developing consumer-friendly sensing...
Deadline Extended for Photonics Prism Awards
BELLINGHAM, Wash., and PITTSFIELD, Mass., Sept. 23, 2013 — Entries are now being accepted through Oct. 11 for the prestigious 2014 Prism Awards for Photonics Innovation. The new extended deadline reflects a permanent change in the annual awards program, responding to requests to move the date out of the...
Human/Insect Lens Adds Depth to Wide-Angle Views
COLUMBUS, Ohio, Sept. 19, 2013 — A new lens that combines the focusing ability of the human eye with an insect’s wide-angle view could help make a confocal microscope with no moving parts, or improve surgical imaging. "Our eye can change focus. An insect eye is made of many...
Haptic Optical Tweezers Let Us ‘Feel’ Microstructures
PARIS, Sept. 16, 2013 — A new technology called haptic optical tweezers allows microscope users to manipulate samples by sight and touch, which could improve dexterity of micromanipulation and microassembly. The tweezers “will become an invaluable tool for force...
Bruker Acquires Prairie Technologies
BILLERICA, Mass., Sept. 13, 2013 — Scientific instruments provider Bruker Corp. has acquired Prairie Technologies Inc., a provider of fluorescence microscopy products. Specific terms were not disclosed. Madison, Wis.-based Prairie generated revenues of approximately $11 million in...
Sculpted Light Captures Brain Activity
VIENNA, Sept. 9, 2013 — A high-speed imaging technique that “sculpts” the 3-D distribution of light in a sample can resolve a single neuron in a living worm, opening possibilities for studying the function of the organism’s nervous system and pairing...
Laser-Based Tool Tells Normal Tissue From Tumors
ANN ARBOR, Mich., & CAMBRIDGE, Mass., Sept. 5, 2013 — A new laser tool can microscopically distinguish between normal and cancerous brain tissue in real time. Since it doesn’t miss cells that could trigger new tumor growth, the method could make brain cancer surgery much more effective.
Edmund Optics Awards Higher Education Grants
BARRINGTON, N.J., Sept. 4, 2013 — A novel approach to imaging protein-protein interactions, a holography-based technique to studying disease, and a new kind of instrument for improving the largest ground-based optical telescopes were announced Wednesday by Edmund Optics as the first...
Superbright Nanocrystals Advance Biosensing
SYDNEY & ADELAIDE, Australia, Sept. 3, 2013 — The combination of a special kind of nanocrystal known as a SuperDot™ and a unique optical fiber that enables light to interact with nanoscale volumes of liquid has allowed the detection of a single nanoparticle from a distance using light. These...
Decoration deciphered on Stradivari violin
Sep 1, 2013 — Historians, artists and music lovers have long debated the merits of a Stradivari violin: Are the materials or the methods responsible for the unsurpassed sound quality, or did the 17th-century master just have a sixth sense that told him how best...
Fluorescent fingerprint tag IDs ‘hidden’ prints
LEICESTER, England – Criminals might want to think twice before touching anything, now that a new fluorescent tagging technique could yield more usable results from latent fingerprints on metal surfaces. The odds that any two people have identical fingerprints are 64...
Microscopy technique could help make 3-D components
GAITHERSBURG, Md. – A technique developed several years ago to improve optical microscopes has now been applied to monitoring the next generation of computer chip circuit components, providing a crucial tool for developing 3-D components. Through-focus scanning optical...
Optical chip enables affordable holographic displays
CAMBRIDGE, Mass. – When Daniel Smalley saw the Mark II holographic video display at MIT, he had to have one. And he will, thanks to a new approach he devised that could produce reasonably priced standard-definition, full-color holograms. “I had to come up with...
Optical microphone listens with light
OSLO, Norway – A nearly 1-mm-thick optical sensor that measures minute movements and extremely quiet sounds could improve the sensitivity of microphones and give them a sense of direction. The technology could enable microphones to “see where the sound comes...
For Phasing Nanocrystals, Size Really Matters
BERKELEY, Calif., Aug. 27, 2013 — Size is of much greater importance than previously believed in metal nanocrystals undergoing phase transformations, a finding that has important implications for the future design of hydrogen storage systems, catalysts, fuel cells and batteries.
Lab Combines Light, Electron Microscopy Devices
WARSAW, Poland, Aug. 21, 2013 — Nencki Institute’s new Neurobiology Centre has installed a combination of light and electron microscopy devices to help researchers better understand the structure, function and capabilities of the human brain. The center’s Laboratory of...
Nanostructured Holograms Control Light’s Intensity, Phase, Polarization
CAMBRIDGE, Mass., Aug. 21, 2013 — By combining cutting-edge nanotechnology with holograms, applied physicists at Harvard demonstrated a novel way for changing the intensity, phase and polarization of light rays.
