Technology Close-Up
What do inspection machines, camera strobes, airplanes, operating rooms, lasers, extraterrestrials and Broadway stages have in common? They need high-intensity lighting. Xenon lamps have found their way into all of these applications -- except maybe for extraterrestrials -- because of their brightness, wide spectral distribution, color balance and long-lived light. ABCs of xenon lamps Xenon lamps...
Staff Report: Growing by Design
Anybody who has blasted music from a cranked-up stereo system is probably familiar with the hiss emitting from the speakers between songs. The sound, which comes from the amplifier electronics, is...
Photonics Design and Solutions
We, as polishers, are constantly pursuing the perfect surface. We want it flat -- very flat -- and we want it smooth -- very smooth. But what does that really mean? Is root mean square (rms) surface...
Let’s Get Small
