Aspherical Lenses are made with the aspheric front curves of plus lenses flatten as they approach the edge of the lens and the curves of minus lenses steepen near the edge. This creates a flatter, thinner and lighter lenses, and a remarkable improvement in wearing comfort. The unique aspheric surface design in combination with the low base curve minimizes distortion at the edge of the lens, providing exceptionally clear vision and better cosmetics. Aspheric lenses provide a more natural look because the lenses sit closer to the eye (the result of their flatter curves). This produces less magnification for plus lenses and less of the "small eyes" look associated with strong minus lenses....

The Air Knife (Standard) provides good performance with a 30:1 air amplification ratio that is less efficient that the Advanced Air Knife. Air consumption is ~3.4 SCFM per inch at 80 PSIG. The Air Knife (Standard) is a good choice when a less expensive alternative is required. It has slightly higher noise levels and uses more compressed air than the Air Knife (Super)....

Electronic components that exploit the phenomenon of superconductivity could allow us to study the collective behaviour of large numbers of neurons operating over long timescales. That is the finding of scientists in the US, who have shown how networks of artificial neurons containing two Josephson junctions would outpace more traditional computer-simulated brains by many orders of magnitude. Studying such junction-based systems could improve our understanding of long-term learning and memory along with factors that may contribute to disorders like epilepsy. The human brain consists...
University of Pittsburgh researchers have conducted the first cradle-to-grave assessment of light-emitting diode (LED) streetlights and determined that the increasingly popular lamps strike the best balance between brightness, affordability, and energy and environmental conservation when their life span-from production to disposal-is considered. LEDs consist of clusters of tiny, high-intensity bulbs and are extolled for their power efficiency and clear luminosity.Engineers in the Mascaro Center for Sustainable Innovation based in Pitt's Swanson School of Engineering compared LED streetl...
New laser application centre targets the electronics, photovoltaics and flat-panel display marketsJenoptik has opened the doors to a new laser application centre based in the the southern Korean city of Pyeongtaek. The company has invested $4.4 million (€3.4 million) in the centre, which houses laser processing systems ideal for customers looking to do everything from initial testing through to pilot and small production runs.

Scientists at IBM have used nano-engineering techniques to make the world's fastest "avalanche photodetector". Such devices are used in telecommunications networks and the work is an important advance in the field of optical communications. The photodetector is made using germanium, which is compatible with silicon-chip-making technology and could therefore find use in next-generation high-performance computer systems. Computer processors communicate with each other over millions of tiny copper wires. Scientists would ideally like to use pulses of light instead of electri...

Researchers in Japan have made the first superconducting hydrocarbon material by adding potassium atoms to picene (C22H14). The material becomes superconducting at temperatures below 18K – something that has surprised physicists and could provide clues about the physical origins of superconductivity. An important challenge facing physicists is understanding exactly why some materials conduct with zero electrical resistance at relatively high temperatures (up to 138K in cuprates), while others must be chilled to near absolute zero before this superconductivity occurs. To solve...
