The 6267 Replacement Xenon Lamp is filled with purified xenon at 5-20 bar. The pressure triples during operation. This 500 watt Xenon lamp with a 1.6 x 1.1 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. Ultraviolet radiation below 242 nm produces toxic ozone. Consider this ozone free lamp if you don’t need the very short wave ultraviolet below 260 nm.
