Xenon (Xe) Arc Lamps

Overview

Xenon (Xe) arc lamps have a relatively smooth emission curve in the UV to visible spectrums, with characteristic wavelengths emitted from 750-1000 nm. Their sun-like emission spectrum and approximately 5800 K color temperature make them a popular choice for solar simulation, as well as absorption and fluorescence and source spectral scanning applications. Ozone free, UV enhanced, and high stability versions are available across wattages from 75 W to 1600 W.

Ozone Free Xenon Lamps

UV wavelength emissions below approximately 260 nm create toxic ozone, so an ozone free lamp coated to remove unwanted UV wavelengths is a convenient option when the application does not require deep UV output. Ideally, an arc lamp is operated outdoors or in a well-ventilated room, or with an Ozone Eater accessory.

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 a standard Xe arc lamp while also providing high intensity UV output.

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.

Arc Lamp Safety

Arc lamps may emit dangerous levels of UV radiation depending on their source type, so only authorized personnel wearing UV protective eyewear, clothing, and gloves should be in the vicinity of an operating source. Newport recommends using an electronic shutter to block the beam when the source is not in use but remains turned on.
