Being the delicate optical instruments that they are, spectrometers are pretty picky about light.
A new light source based on fiber-optic technology promises to improve the inspection of food, produce, paper, currency, recyclables and other products.
Researchers using nanotechnology have taken a step toward creating an "optical cloaking" device that could render objects invisible by guiding light around anything placed inside this "cloak."
Analyzing human blood for a very low virus concentration or a sample of water for a bioterrorism agent has always been a time-consuming and difficult process.
University of Arkansas researchers have examined the mechanisms underlying the synthesis of three-dimensional nanocrystals in solution and have created a systematic method for the directed synthesis of such nanocrystals.
Harnessing its influence as a national center of research in space technology, the University of Arkansas will host the Advanced Microelectronics and Photonics for Space Conference and Small Business Innovation Research Forum this week at the Arkansas Research and Technology Park.
Argonne National Laboratory scientists in collaboration with Xradia have created a new X-ray microscope technique capable of observing molecular-scale features, measuring less than a nanometer in height.
A new science 'biophotonics' has a new center of operations. Quarters for the National Science Foundation-funded UC Davis Center for Biophotonics Science and Technology were dedicated Monday in the Oak Park Research Building at 2700 Stockton Blvd.
For those who've reached the age when reading a newspaper means holding it at arm's length or fumbling for reading glasses, wavefront-optimized lens technology may offer a better solution, according to data presented at the recent American Academy of Ophthalmology's 2006 Joint Meeting.
The Internet is often called the information superhighway, but the real superhighway is the optical fiber that connects computers around the world at the speed of light, according to John Badding, Penn State associate professor of chemistry.
Advanced Electronic Packaging has helped thousands of students and practicing engineers understand the complex task of connecting integrated circuits and other electronic components to make virtually every electronic device, including cell phones, video games, computers and military- and medical-imaging equipment.
Cornell University researchers have created a broadband light amplifier on a silicon chip, a major breakthrough in the quest to create photonic microchips.
In efforts that can improve studies of biological objects and the construction of nanotech materials, researchers at the University of California-Berkeley have invented "optoelectronic tweezers," a new way of controlling nanometer-scale objects.
Peter Zoller, professor of physics at the University of Innsbruck and scientific director of the Institute for Quantum Optics and Quantum Information at the Austrian Academy of Sciences, has won the Dirac Medal 2006.
In an effort to combine sophisticated laser and Internet technologies, scientists in Australia have successfully performed laser surgery and "optical trapping" in a Southern California laboratory via the Internet.
