Resurfacing Fattens up Big Lens
Jul 1, 1997 — A team of astronomers at the University of Arizona had a second try at creating the world's largest one-piece telescope mirror June 10. In April, it was discovered that 2 tons of glass had leaked out from the 8.4-m mirror and in certain places the...
Technique Offers Real-Time 3-D Microscopy for Materials
Jul 1, 1997 — JENA, Germany -- German microscope manufacturer Carl Zeiss Jena GmbH has developed a technique that it says provides three-dimensional, real-time microscopic images with the high resolution and sharp contrast of conventional light microscopy.The...
Sapphire Could Become Interferometry's Crowning Jewel
May 1, 1997 — NEDLANDS, Australia -- The gemology community considers sapphire to be one of the most precious stones on Earth, and researchers believe that the blue crystals' use as beamsplitters in laser interferometer gravitational wave detectors could be just...
Infrared Imager Helps Evaluate Papermaking Process
Apr 1, 1997 — The papermaking industry is among the highest consumers of energy in the US, and researchers at the Institute of Paper Science and Technology (IPST) in Atlanta are working to make the process more energy efficient. They chose Secaucus, N.J.-based...
Side-Pumping Diodes Mean More Power for Materials Processing
Apr 1, 1997 — SUNNYVALE, Calif. -- A novel technology in which a side-pumped laser diode drives a solid-state laser source could mean more power and greater precision for materials processing applications, say the scientists who developed it. Use of diode lasers...
Nifty 'Trick' Leads to First 3-D Optical Gratings
Mar 1, 1997 — Scientists at Lucent Technologies in Murray Hill, N.J., and The Netherlands' Utrecht University have discovered how to "trick" billions of glass spheres, each about as wide as one wave of visible light, into forming 3-D optical gratings. Researchers...
Standard Published for Optical Fiber Coating Removal
Feb 1, 1997 — A new standard published by the Telecommunications Industry Association (TIA), titled "Measurements of Strip Force for Mechanically Removing Coatings from Optical Fibers," quantifies the force needed to remove coatings from fibers along the...
X-Ray Microcalorimeter Developed for Improved Materials Analysis
Feb 1, 1997 — An x-ray microcalorimeter developed by the National Institute of Standards and Technology could improve materials analysis in the semiconductor industry. The device, compatible with commercially available scanning electron microscopes, can achieve...
A Bright Future for Organic Light-Emitting Diodes
Jan 1, 1997 — Organic materials are part of our everyday life, but only recently have photonic devices begun to exploit their versatility. For more than 20 years it was common knowledge that organic crystals exhibited electroluminescence when large voltages were...
Bright Days Seen Ahead for Optical Coating Industry
Jan 1, 1997 — NORWALK, Conn. -- Steady growth through the turn of the century is the forecast for the worldwide optical coating market, says a report from Business Communications Co. Inc. (BCC). The growth is expected to be buoyed by expanded use in medical and...
Imager Helps Standardize Process Transfers
Jan 1, 1997 — In the advanced materials processing arena, the use of low-pressure gas discharges is on the increase in applications such as the creation of submicron microchip architectures and thin diamond film deposition. Plasma conditions and processes are...
Nearing the End of the Road
Dec 1, 1996 — MAINZ, Germany -- The fourth and final glass/ceramic mirror substrate for the Very Large Telescope has been sent from Schott Glaswerke to R.E.O.S.C. near Paris for final finishing. Each of the 8.2-m mirrors took 23 months to complete and will be in...
Irish Research Institute Chooses Belgian Micromachining System for New Lab
Nov 1, 1996 — The National Micro-Electronics Research Institute of Cork, Ireland, is establishing a laser micromachining laboratory within its NMRC Materials Group that will use the LightDeck Micromachining System from Optec of Hornu, Belgium. The institute chose...
New Semiconductor Materials Yield Broadband Amplifier Fiber
Nov 1, 1996 — SYRACUSE, N.Y. -- A new fabrication technique has created cylindrical optical fibers that promise to enable small broadband optical amplifiers for use in communications networks, according to university researchers who have created the technology...
