Research Arc Lamp Housings allow DC arc lamps to operate with optimum performance while providing a safe operating environment for the user. Choose from a wide selection of lamp wattages, condensing lens types, and flange sizes. By choosing a lamp housing that meets their wavelength output and output beam characteristic requirements, users are choosing a versatile component capable of operating many of the DC Arc Lamps that are sold separately.
A rear reflector is built into the lamp housing to collect back scatter from the lamp that would otherwise be lost. An estimated 60% increase in output intensity from the lamp housing is observed due to this rear reflector. Due to small manufacturing differences between lamps, the rear reflector needs to be adjusted when a new lamp is installed.
Due to small manufacturing differences between lamps, the rear reflector position and lamp position relative to the condenser lens must be adjusted when a new lamp is installed in the housing. Adjustment knobs located on the exterior of the lamp housing allow for optimum positioning of the lamp and rear reflector.
A temperature sensor inside the lamp housing monitors the lamp's operating temperature and controls the cooling fan accordingly. This keeps the lamp at a safe temperature for operation and ensures the temperature required for proper wavelength emission of the lamp is maintained. The Research Lamp Housing also includes as Safety Interlock Feature. If the lamp housing door or interconnection cable to the power supply are not firmly secured, the lamp will not ignite or voltage supply to the lamp will cease. This protects the user from accidental exposure to UV radiation and high voltage.
Starting an arc lamp requires a pulse ranging from several hundred to several thousands of volts to excite the gas between the lamp's electrodes. An ignitor is built into the lamp housing to meet this requirement.
Output flanges of 1.5 inches, 2 inches, and 3 inches are coupled to the output of these Research Lamp Housings. The output flange size determines the diameter of the collimated output beam and should also be considered based on what component the lamp housing will be coupled to. Flange couplers and adaptors for interchanging between different flange sizes are offered if this is required to couple the lamp housing to a monochromator or other piece of equipment.
Oriel® offers Research Lamp Housings capable of operating two different ranges of lamp wattages: 50 to 500 W and 450 to 1000 W. All Xenon, Mercury-Xenon, and Mercury arc lamps can be operated in the lamp housing that matches their lamp wattage. The appropriate socket adapter, Lamp Housing Interconnection Cable, and Arc Lamp Power Supply is also necessary to operate the lamp. Check out the Compatibility guide below for more information.
Oriel uses three different types of lenses to use in Condenser Lens configurations. These lens types differ in cost and quality of output beam collimation quality:
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 an Ozone Eater.
