Xenon Arc Lamp, 450 W, UV Enhanced
The 6278 Replacement UV Enhanced Xenon Lamp is filled with purified xenon at 5-20 bar. The pressure triples during operation. This 450 watt Xenon lamp with a 0.9 x 2.7 mm effective arc size operates with the anode at the top. The small intense arcs radiate like 5500-6000 K full radiators with some xenon lines superimposed. The xenon lines dominate between 750 and 1000 nm, but the spectrum is almost featureless through the ultraviolet and visible. Xenon lamps are popular for demanding absorbance and fluorescence applications involving source spectral scanning, and as high intensity broadband sources. Because of its sun-like spectrum, the xenon lamp is used for solar simulation.
UV-Enhanced Xenon Lamps
When additional UV output from the xenon lamp is required, UV-enhanced lamps are available. These lamps provide the same visible to NIR performance of an standard Xe arc lamp while providing high intensity UV output as well.
High Stability Xenon Lamps
High stability Xe arc lamps are made of a higher quality cathode than typically used for xenon arc lamp construction. As a result, no arc wander occurs, allowing the lamp to maintain a consistent output intensity throughout its lifetime.
Xenon Lamp Shelf Life
We recommend purchasing replacement xenon lamps only as needed. Xe arc lamps do have an unspecified shelf life, which over time can cause the end cap seals to leak and degrade lamp performance. Newport strives to keep Xe bulbs in stock to reduce lead times when ordering a replacement.
