450 W Xenon lamps are offered in UV Enhanced or Ozone Free versions. Xe lamps have a white light output very similar to the sun and a high color temperature, making these lamps useful for solar simulation. These lamps are also popular for wafer inspection. 6279NS Ozone free lamp is excellent option when wavelength emission below 260 nm are not required. If an ozone creating lamp must be used, it is recommended to use the light source near a ventilation port or outdoors. For users requiring the output of a Xe arc lamp with additional intensity in the UV region, 6278 UV Enhanced Xe arc lamp is offered.

The 69920 power supply provided with these light sources is a highly regulated power supply. Much of an arc lamp's stability in wavelength and output intensity is due to keeping the temperature and pressure of the gas inside the lamp's envelope as constant possible. The 69920 power supply provides highly stable voltage and current supply to the arc lamp, keeping the arc lamp's ripple to less than 1% rms while maximizing the lifetime of the lamp.

Oriel's Research Lamp Housings are designed to focus the output light of the lamp to the user's needs while providing an ideal environment for lamp operation and user safety. A built in temperature sensor and cooling fan prevents overheating of the lamp during operation. A rear reflector built inside the lamp housing reflects back scatter radiation from the lamp. The collimating lens assembly on each Research Lamp Housing is used to ensure the lamp is properly aligned within the housing and optimally focus the light output to the user’s needs. If the lamp housing door is not firmly secured to the lamp housing or a lamp housing interconnection cable is not firmly secured to its connector, the lamp inside will not ignite or supply voltage and current to the lamp will not be supplied. This protects the user from accidental exposure to UV radiation and high voltage during ignition and operation of the lamp.

Arc lamps may emit dangerous levels of UV radiation depending on their source type. Ensure that only authorized personnel are in the vicinity of the source, and wearing the necessary safety equipment such as UV protective eyewear, clothing, and gloves. Lighted UV warning signs, posted outside laboratory doors where UV sources are operating, can prevent accidental exposure. Newport also recommends using an electronic shutter to block the beam when the source is not in use but remains turned on. Alternatively, the beam can be safely contained by using beam tubes or fiber optic cables to deliver the light to a sample. It is recommended to vent the ozone that is produced by some lamp models to the outside or use the 66087 Ozone Eater.
