66983 Xe Arc Source, shown with 68950 Light Intensity Controller.

Why These Sources?

We offerSimpicity Series Arc Sources and these fully featured sources. The difference is the power supply; these systems include a power supply that allows:

•Remote control and monitoring of lamp via RS232 or IEEE 488 computer interface

•Monitoring of lamp’s usage in accumulated lamps hours

•Compatibility with the Oriel® Light Intensity Control System for long term output stability

•Interchangeable lamps

Lamp Housing

These aluminum housings hold the ignitor, lamp, and collecting and collimating optics. A number of safety features protect personnel from dangerous UV and keep the lamp and optics from overheating. A socket adapter holds the lamp in the lamp housing. To switch between lamps, change the socket adapter. External adjustment knobs allow lamp position alignment.

Power Supply

The 69911 Power Supply is dedicated to Xe and Hg(Xe) lamps in the 200 to 500 watt power range. It is rugged, reliable and highly regulated. In addition to superior performance, this supply has a number of features to facilitate source operation.

Easily Interchangeable Lamp

You can operate any of the lamps listed in Table 1, in the same housing. All sources come with your choice of lamp and appropriate socket adapter; please specify the lamp when ordering a source.

The 450 W Xe lamps, models 6261, 6262 and 6266, will not run in these sources. These lamps are over 10 inches (25.4 mm) tall and do not fit in the lamp housing. The 500 W Xe lamp, model 6267, runs at 30 A; the upper current limit of the power for these sources is 25 A. Both lamp types require the1000 W Systems.

Which Sources Do I Choose?

We offer various 200 - 500 W Xe Research Sources differing only in the lamp housing condensing lens assembly. Table 1 lists the choices. The new asphere condensers are "corrected optics." Their design ensures that they are corrected spherical aberration and lateral chromatic aberration with minimized longitudinal chromatic aberrations.

*Does not include the rear reflector (included in the source) contribution of ~60%. We offer formulae and sample calculations to compute the approximate total output power from your source.

Mounting

Our 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 66075 Carrier Mounting Kit. The kit includes a clamping carrier.

Extended Care Plan

You can now extend the warranty on these sources to two years with the Extended Care Plan. Contact us for details.

Safety Considerations

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 ourOzone Eater. To protect yourself from the dangerous UV, wear protective eyewear and gloves.
