Xenon: A 'Bright' Choice for Machine Illumination
Dave Jacobsen and Patricia Katzman
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 are either continuous-wave (CW) or strobe systems. The CW lamps are desirable for machine vision applications that require uninterrupted light and a good color balance. Xenon strobes, or flashlamps, produce short-duration pulses of high-intensity light...
