Speedy Spectroscopy of Single Nanoparticles
Nanoparticles present distinct research problems. Because of variations among production batches, investigators tend to choose to study individual particles. Doing so, however, is technically challenging, and it is difficult to generate meaningful data. By using an LCD at the entrance of the spectrometer as an electronically addressable shutter, researchers created a single-particle spectroscopy setup that is at least 10 times faster than other methods for studying large numbers of...

Getting the ‘Hole’ Picture Up Close
Plasmons — local electron oscillations in metal films — hold great promise as the basis for sensors and optical switches. A challenge with such substrates has been pinpointing the location of the highest plasmonic signal -- knowledge of which could...

Gigabit Ethernet Cameras Inspect Paper and Steel
Paper and steel manufacturing pose a variety of challenges for inspection systems. Endless streams of material must be checked for flaws early on before the material is packaged, bundled or processed further. Material movement, surface texture and...

Hyperlens Achieves 130-nm Resolution
Because metamaterial-based lenses can overcome the diffraction limit of light waves, they may enable optical imaging of objects much smaller than typical lenses can resolve. Researchers from the University of California, Berkeley, achieved 130-nm...

Integrated Wavelength Control for Diode-Pumped Lasers
Diode-pumped solid-state laser systems are replacing flashlamp-pumped lasers in many applications because diode pumping results in better overall wall-plug efficiency and beam quality than lamp pumping. Furthermore, diode pumping is the only...

Interlaced Goes Digital
Although industrial digital cameras for the machine vision market were introduced nearly 20 years ago, about 65 percent of all camera units sold in North America are still analog, according to the Automated Imaging Association. The main reason is...

Microscope Slide Enables ~70-nm Resolution
Conventional optical microscopes can resolve objects on the order of only 200 nm because they are limited by the diffraction of light waves, meaning that small things such as DNA and viruses cannot be seen. Although both scanning probe and electron...

Photonics for Art’s Sake
Art may be for art’s sake, but that doesn’t mean that paintings and other works of art can’t benefit from photonic-based tools and equipment. For example, the challenge of preserving and restoring artwork from the past and present is made easier by...

Are Quantum Dots on the Brink of Their Big Break?
The period at the end of this sentence would be colossal next to a quantum dot — like a flea clinging to a good-size dog. As many as a million quantum dots could perhaps fit within the narrow confines of this circle: o. In other words, quantum...

Eye Safety in the Laser Lab
Thinking about installing a laser safety interlock on the door to your Class 4 laser lab? If so, you might want to give that decision some careful consideration. A safety interlock that stops the laser or blocks the laser beam (with a shutter) if...
