Series Q Arc Lamp Sources

The Series Q are our most popular low wattage arc lamp sources, and it's easy to see why: they are adaptable without being complicated to operate, highly stable, and economically priced. We offer various models of Series Q Arc Sources; the difference is in the lamp-housing condenser. Some condensers are intended for collimated beams, but can also be positioned to produce a diverging or converging beam. We also offer focused output models. All have a 1.5 Inch Series female flange. These systems include everything you need to begin your work. They run Hg and Xe arc lamps from 50 to 100 W. See our Information on Spectral Irradiance Data for curves of these lamps.

Why a Series Q Source?

Oriel offers various low wattage arc lamp sources; what makes the Series Q models so special? The difference is the lamp housing. The Series Q Housing supports up to four output ports for simultaneous irradiance of multiple samples (our other housings only have one output port.) These sources only include one condensing lens assembly. For multiple outputs, order additional condensing lens assemblies.

What Does a Series Q Arc Lamp Source Consist of?

The sources described on these pages consist of:

• 60000 Series Q Lamp Housings with one condenser, rear reflector, X, Y, Z lamp position adjusters and built-in ignitor
• Model 69907 Power Supply
• Choice of DC Short Arc Lamps, and appropriate lamp socket adapter
• All necessary cables and mounting hardware

60000 Series Q Lamp Housing

The 60000 uses natural convection cooling to maintain a stable output. External X, Y, Z lamp adjusters let you place the arc where you want it, simplifying fiber and slit illumination. An adjustable reflector collects the lamp's back radiation, increasing output by up to 60%. You can add a second condenser and a second reflector assembly to the Series Q, and illuminate two targets simultaneously. Place a different bandpass filter on each output and you have two different sources! We also offer a new Series Q Housing that uses a hinged cover (model 60030 ), to allow easier access to the lamp. This model only supports three output ports. For a Series Q Arc Source with the 60030 Hinged Housing, contact a Sales Engineer.

Power Supply

The 69907 is a highly regulated source of constant current, or power, for low power arc lamps. When combined with the Series Q Housing, output ripple is less than 0.1% rms. Additionally, it has a number of useful features:

• Standard RS 232 and optional IEEE-488 (GPIB) for remote lamp operation
• Digital display of lamp power, current, voltage, and lamp usage hours
• Ability to store multiple lamp set-ups
• Built-in self-diagnostics

Interchangeable Lamps

Use the following socket adapters to run these lamps in the Series Q.

Which Source Should I Choose?

We offer various models of Series Q Arc Sources; the difference is in the lamp-housing condenser. Table 2 summarizes the choices. The asphere condensers are "corrected optics." Their design ensures that they are corrected spherical aberration and lateral chromatic aberration with minimized longitudinal chromatic aberrations. All have a 1.5 Inch Series female flange.

Mounting

The Series Q Lamp Housings have leveling feet for free standing use. The height may be adjusted 0.63 inches (16 mm). For mounting to inch or metric optical tables, remove the feet and use the proper mounting holes. The optical axis is then 5.0 inches (127 mm) above the table.

Safety Considerations

Arc lamps emit UV radiation, which may be hazardous. We recommend that you wear UV protective glasses or goggles, and gloves when working with these sources. We offer Ultraviolet Safety Equipment.
