Partnership Gathers Support for Hybrid Lighting
Jan 1, 1999 — Lighting is the single largest energy user in commercial buildings, consuming about one-third of the total electricity. The Hybrid Lighting Partnership -- at this point still an informal group of 10 companies and the US Department of Energy's (DoE)...
Photometer/Theodolite Analyzes F-16 Head-up Display
Jan 1, 1999 — The F-16 Flying Falcon, widely regarded as the world's most versatile military aircraft, owes some of its acclaim to the pilot's head-up display, which delivers real-time information about target location, navigation and weapons systems through...
Thin-Film Coating Applications Heat Up
Jan 1, 1999 — Optical coatings are one means of controlling heat in lighting applications such as film projectors and microscope illumination systems. Unfortunately, suppliers of multilayer dielectric coatings have primarily emphasized spectral performance,...
Handheld Spectroradiometer Tests Sunlamps
Dec 1, 1998 — New legislation in France has put a limit on the permissible amount of radiation in the ultraviolet B (UVB) range from sunlamps. Many officials charged with examining the UVB output of the approximately 12,000 lamps regulated under the legislation...
Integrating Sphere Aids Absolute Calibration of Lamps
Dec 1, 1998 — Manufacturers of lamps, bulbs and other light sources use integrating spheres to measure in lumens the emitted visible light, or luminous flux, of their products. In addition to reporting this information to customers, manufacturers can gauge...
Space Mirror to Light up the North
Nov 1, 1998 — In February, night may become more like day in some cities across the Northern Hemisphere, as cosmonauts aboard the space station Mir deploy a giant, 25-m reflector and direct its light Earthward. The light could be as much as 10 times brighter than...
Feds Postpone Laser Safety Tests
Oct 1, 1998 — The delayed delivery of a laser has held up evaluations of the US Federal Aviation Administration's guidelines for laser exposure within 10 nautical miles of an airport. The tests, which were scheduled to begin earlier this year at the agency's Mike...
Conoscopy Assesses Displays
Sep 1, 1998 — Liquid crystal displays are gaining market share. As prices fall, users want brightness and viewing angles comparable to that of conventional displays. A display's visual performance usually is measured with goniometric methods based on mechanical...
Advances in Polymer Gels Pave Way for Sensors, Displays
Aug 1, 1998 — Physicists at the University of North Texas in Denton have conducted trials using a type of polymer gel called a hydrogel that may play a role in new display or sensor technologies. The hydrogels swell or shrink when environmental stimuli such as a...
Consumer Goods
Aug 1, 1998 — The Internet, personal computers and the rise of a culture that needs to quickly send words, images and data around the world are driving improvements in telecommunications. Consumer electronics markets, especially imaging, displays and data...
Demand for Metal Halide Lamps Rises
Aug 1, 1998 — A growing number of news-gathering organizations are turning to metal halide lamps because of their portability, light output and low power consumption. According to Welch Allyn Inc.'s Lighting Products Div., based in Skaneateles Falls, N.Y., which...
NASA Builds Chlorophyll Measurement System
Aug 1, 1998 — Researchers at the John C. Stennis Space Center have developed an optical system for measuring the levels of chlorophyll in plant leaves that can provide an early warning of plant stress. The system is a test bed for both an optical system, designed...
Photonics in Industry
Aug 1, 1998 — Industrial applications of photonic systems are growing steadily as manufacturers realize the benefits of light-based technologies. Laser systems help to create products by cutting, drilling and welding materials; imaging and analysis systems work...
