Xenon Arc Lamp, 75 W, 0.25 x 0.5 mm Effective Arc Size

The 6251NS Replacement Xenon Lamp is filled with purified xenon at 5-20 bar. The pressure triples during operation. This 75 watt Xenon lamp with a 0.25 x 0.5 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. This lamp is compatible with the 66150 Socket Adapter (not included).

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.
