Mercury lamps are excellent sources of high intensity DUV-VIS spectral lines; they are widely used as excitation sources. The systems described here run our 200, 350 and 500 W Hg lamps. You can interchange between lamps by simply changing socket adapters in the lamp housing. These sources consist of:
• Oriel Research Arc Lamp Housings with a condenser and a built-in ignitor as indicated per Model number in the table above
• OPS-A500 Power Supply
• Hg DC arc lamp as specified per Model number in the table above
• 70051 Lamp Housing Interconnection cable
The 67001 , 67005 , 66901 , 66902 , and 66905 can properly house and operate any 50-500 W DC arc lamp. If a light source from the above table is purchased, other DC Hg arc lamps can be used simply by changing the socket adapter and lamp inside the lamp housing. The appropriate socket adapter for each lamp is shown in the table below:
| Mercury Arc Lamp | Lamp Wattage | Effective Arc Size (mm x mm) | Socket Adapter |
|---|---|---|---|
| 6283NS | 200 | 0.6 x 2.2 | 66144 |
| 6286 | 350 | 0.8 x 2.7 | 66161 |
| 6285 | 500 | 1.1 x 4.1 | 66162 |

The housing provides a temperature controlled, stable environment for the lamp, and protects personnel from the harmful UV radiation emitted by the lamp. A number of safety features are incorporated into the housing to prevent accidental exposure and lamp overheating. It also houses the ignitor and collimating lens assembly. A socket adapter holds the lamp, vertically, in the center of the lamp housing. To use another suitable lamp with the existing lamp housing, a different socket adapter must be used. External adjustment knobs allow for alignment of the lamp. A reflector mounted behind the lamp collects the lamp\'s back radiation and redirects it to the condenser, maximizing light output.
Various lamp housings are available for the 200-500 W Hg Research Arc Lamp Sources. Each lamp housing has a unique condensor lens assembly mounted to it. The optical characteristics per each lamp housing below should be considered when selecting a light source.
The new asphere condensers are corrected optics. The design corrects spherical aberration and lateral chromatic aberration with minimized longitudinal chromatic aberrations.

The OPS-A500 power supply is dedicated to 200-500 W DC arc lamps. It is rugged, reliable and highly regulated. It operates any of the specified lamps under extremely tight power or current control. In addition to superior performance, this supply has a number of features to facilitate source operation. External control of the OPS-A500 can be done via USB or RS 232 interface.
Oriel lamp housings have adjustable height instrument feet. You can remove these and hard mount the housing to inch or metric optical tables and baseplates. The optical axis is 4.0 inches (102 mm) above the table. To mount a housing to a bench or rail, order the Carrier Mounting Kit. The kit includes a clamping carrier.
These sources emit dangerous levels of UV radiation and ozone. If you do not need output below ~260 nm, choose an ozone free lamp. If this is not an option, vent the ozone to the outside or use our Ozone Eater™ Ozone Converter. To protect yourself from the dangerous UV, wear Ultraviolet Safety Equipment like protective clothing, eyewear and gloves.
