Newport MKS Xenon Short Arc Lamp, 450 W, Ozone Free 6280NS

The 6280NS Xenon Short Arc Lamps closely matches the UV-VIS solar spectrum with a smooth continuum from UV-VIS. This 450 Watt Ozone Free Xenon lamp is filled with purified xenon at 5-20 bar. The pressure triples during operation. Xenon lamps operate 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. Ozone Free Xenon Lamps UV wavelength emissions below ~260 nm create toxic ozone. Ideally, an arc lamp is operated outdoors or in a room with adequate ventilation to protect the user from ozone created. If this is not possible, an Ozone Eater should be used. However, if the application does not require wavelength emission below ~260 nm from the arc lamp, using an ozone free lamp is a convenient option. An ozone free lamp is coated to remove the unwanted UV Wavelengths 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. 450 to 500 W Xenon (Xe) Lamps 6278 and 6279NS Spectral Irradiance
