Sandia Researchers Take Cue from Seashell Design
Sep 1, 1998 — Rarely do scientists mention seashells and optical coatings in the same sentence. That may soon change now that researchers at the US Department of Energy's Sandia National Laboratories and the University of New Mexico in Albuquerque have disclosed...
Silver Coating Maintains Reflectance
Sep 1, 1998 — Although the reflectors behind the xenon flashlamps that pump the Nd:glass amplifiers in the National Ignition Facility's 192 laser beams might seem at most a secondary concern, their reliability is important. Lawrence Livermore National...
Coating Method Makes Molecule-Thick Layers
Jun 1, 1998 — A method for dip coating a substrate with organic polymers may increase the efficiency of light-emitting diodes (LEDs) and computer displays while reducing costs and environmental hazards. The technique, being explored by a group of MIT researchers,...
Laser Texturing Slashes Cylinder Wear
Jun 1, 1998 — Laser texturing of engine cylinder walls may reduce oil consumption by 40 percent compared with traditional cylinder machining techniques, according to a manufacturer of engine honing equipment. Machine honing of engine cylinder walls gives them...
Spectra-Physics Wins $2.4 Million Contract for Optical Coatings
Jun 1, 1998 — Spectra-Physics has received a $2.4 million contract to develop optical coatings for the National Ignition Facility. The facility's laser system will require 8000 large optical components and 30,000 smaller ones. Spectra-Physics will manufacture the...
Names in the News
May 1, 1998 — BrainTech Inc. received a contract to build and install a print-quality inspection system to improve and standardize the ink jet printer assembly process for Epson Portland Inc. Epson has the option to buy an additional 11 units to automate its...
Software Eliminates Guess-Work from Coating Designs
May 1, 1998 — The possibility of having true global optimization for a large number of variables such as in multi-layer thin film design, has been debated for decades. A true global optimization algorithm works for a variety of different applications to find the...
Cantilever Thermal Detector to Challenge Microbolometer
Mar 1, 1998 — Researchers at Oak Ridge National Laboratory have developed an uncooled thermal infrared detector that they hope will cut the costs of IR cameras by one-third. Researchers Panos Datskos and Slobodan Rajic have developed a microcantilever,...
Three-Laser Method Goes Beyond Diamond Films
Mar 1, 1998 — Three years after unveiling an advanced method for depositing diamond thin coats, QQC Inc. has disclosed that it used the same three overlapping pulsed lasers to improve the surface of metals, ceramics and polymers. The multilaser process gained...
Optical Coating Absorbs in UV Range
Feb 1, 1998 — Reducing stray light is a problem that engineers often encounter when designing optical instruments. One method of achieving this reduction is to apply absorptive coatings on an instrument's critical components. Applications for the coating are...
Optics Test Could Affect Future Microchips
Feb 1, 1998 — A recent test of optical coatings at MIT may lead to increased interest in solid-state light sources for next-generation microchip lithography. MIT staff scientist Vladimir Liberman conducted the study to evaluate the state of excimer-grade fused...
High Power Laser Optics:
Jan 1, 1998 — As power levels rise above 5 kW, optics become critical to the performance and reliability of laser systems. These applications demand consistent laser-quality ZnSe that is defect free and has bulk absorption at or near theoretical values. Other...
Laser Vibrometer Heightens Speaker Design
Jan 1, 1998 — The VPI 4000 scanning laser vibrometer produces a clear picture of what is happening on the surface of the speaker. Courtesy of Mackie Design. The company's first loudspeaker product, the HR824, represents its commitment to quality through the...
Software Gauges Efficiency of AR Coatings
Jan 1, 1998 — A British researcher has developed software that analyzes new antireflection coatings for optical systems. Geoff Adams, of UK-based Optical Software Co., has developed WinLens for Spindler & Hoyer -- software for designers of multi-glass...
IR Beamsplitter Coatings Reduce Gas Analyzer Size, Cost
Nov 1, 1997 — A manufacturer of gas-analysis equipment had developed a product that could quickly and accurately measure up to 250 hydrocarbon gases, but it was not without its problems. It was a large, expensive instrument. The company determined that a...
Excimer Lasers, High-NA Optics Push Lithography
Jul 1, 1997 — BALTIMORE -- Developments in excimer lasers and high numerical aperture optics technology are pushing photonics into the forefront of semiconductor microlithography, where laser-created feature sizes have already dipped below 0.25 µm.David...
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...
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...
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...
