Haptic optical tweezers let us ‘feel’ microstructures
PARIS – 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 feedback micromanipulation of biological samples and nano- and microassembly parts,” said Dr. Cécile Pacoret of Université Pierre et Marie Curie (UPMC), a co-author of the study. Designing optical tweezers to incorporate

Ultrafast spectroscopy reveals new uses for flawed gems
TUCSON, Ariz. – Ultrafast laser pulses have provided the first detailed observation of how energy travels through diamonds with specific flaws that provide interesting optical and electronic properties. A team led by University of Arizona assistant professor...
Well-rounded molecules make better light emitters
SALT LAKE CITY – The more well-rounded the organic molecule, the better – at least when it comes to maximizing light emission. A team led by the University of Utah working to develop more efficient OLEDs believes it has solved a major problem with...
Schreck Awarded €2M ERC Grant
INNSBRUCK, Austria, Nov. 26, 2013 — Florian Schreck, an experimental physicist at the University of Innsbruck’s Institute of Quantum Optics and Quantum Information, has received a grant from the European Research Council (ERC) worth up to €2 million (about $2.7 million) to...
Monroe Joins Vision Engineering
NEW MILFORD, Conn., Nov. 25, 2013 — Scott Monroe has joined Vision Engineering Inc. as vice president of sales and marketing, the ergonomic microscope manufacturer announced recently. Monroe, who previously held sales positions in the Microscopy and Digital Imaging markets at Nikon,...
Geodesy Applications Pursued for Atom Optics
GREENBELT, Md., Nov. 12, 2013 — An atom interferometer under development to measure gravitational ripples in space-time with picometer-level sensitivity could also advance geodesy, the science of measuring the Earth’s size, shape and gravitational field. Technologists...
Shad-o-Box 688, 1548 X-Ray Detection
WATERLOO, Ontario, Canada, Nov. 12, 2013 — Teledyne Dalsa has added models 688 and 1548 to its Shad-o-Box HS digital x-ray detector product line. They are suitable for industrial, biomedical and scientific imaging and for applications including electronics inspection and computed tomography....
ILX Donates Laser Diode Instruments to UCSB
BOZEMAN, Mont., Nov. 2, 2013 — ILX Lightwave donated $12,000 worth of laser diode instrumentation to the Weld research group at the University of California at Santa Barbara last month. Laser diode instrumentation is used to precisely control a laser diode’s optical output...
Big Photonics Advances Build and Power Big Telescopes
Nov 1, 2013 — Bigger aspheric mirrors enable astronomers to see farther into space – but they require special designs. For astronomers, bigger is better: In general, the scientific value of a telescope scales to the fourth power of its diameter. So,...
