Available Configurations

Each light source part number begins with its Legacy Part Number, the predecessor to these light sources. The rest of the part number tells the lamp power and type of lamp included, along with the type of lamp housing and F/# of the condensor lens assembly included with each light source. The part number is explained as follows:

Legacy Part Number - Lamp Power and Type - Housing F/#

The following Q Series Arc Lamp Source configurations are available. Each configuration includes the lamp, socket adapter, 60025 interface kit, 60000 housing, 60005 reflector assembly, collimating lens, lamp housing interconnectoin cable and OPS-A150 power supply as indicated in the table below:

The Series Q are the most popular low wattage arc lamp sources, and it\'s easy to see why: they are adaptable without being difficult to operate, highly stable, and economically priced. Various models of Series Q Arc Sources are offered; the difference is in the DC arc lamp and lamp-housing condenser. Some condensers are intended for collimated beams, but can also be positioned to produce a diverging or converging beam. Focused output models are also offered. All have a 1.5 Inch Series female flange. These systems include everything required for operation. Hg and Xe arc lamps from 50 to 100 W are available per the Light Source Part Number specified in the table above. See Information on Spectral Irradiance Data for curves of these lamps.

Complete Arc Lamp Sources

The Series Q Arc Lamp Source consists of:

• 60000 Series Q Lamp Housings with X, Y, Z lamp position adjusters and 60005reflector lens for collection back radiation inside the lamp housing

• OPS-A150 Power Supply

• 60025 Interface kit for Series Q Housing to OPS-A150

• DC Arc Lamp with appropriate socket adapter and condensor lens assembly to mount to 60000 Series Q Lamp Housings as specified with each Light Source Part Number in the table above

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.

Power Supply

The OPS-A150 is a high stability current and voltage source for operating 50-150 W DC arc lamps. A large LCD screen and easy to use push button and knob conveniently located on the front panel allow the user to navigate through the power supply’s functions. These functions include choice of Power, Current, and Intensity control modes and setting the limits and observing in real time the important parameters of each operating mode. Up to four Setups consisting of these preset parameters can be saved for easy recall in the future. For users that prefer computer control, RS-232 and USB connectors are located on the rear panel to control all of the power supply’s capabilities on a Windows based PC. Additional connectors on the rear panel of the power supply allow for the control of a LIK-LMP Light Intensity Controller Kit (sold seperately). When operating with the LIK-LMP , the power supply is able to maintain the temperature of the detector head from 0-25 ˚C. The OPS-A150 also monitors how long the current lamp in use has been operated, allowing the user to determine when the lamp should be approaching the end of its usable lifetime. The OPS model power supplies are also CE and RoHS compliant.

Interchangeable Lamps

If an Arc Lamp Series Q Light Source is purchased, other 50-100 W DC arc lamps from the table above can be used in the existing lamp housing by interchanging the lamp and socket adapter (if necessary). See the table below to determine which lamp requires which socket assembly for use in the 60000 Q Series Housing. Please note that Xenon lamps require the 70050 lamp housing interconnection cable to connect the 60025 interface kit to the OPS-A150 power supply. If operating a Mercury lamp, the 70051 must be used.

Series Q Housing Compatible Arc Lamps

Series Q Lamp Housing

Oriel\'s Series Q Housing, named for its quiet convection cooling, is one of Oriel\'s most popular housings for low wattage lamps. It\'s price, size, and versatility make it attractive to researchers. The Q Housing allows quick access to the lamp, simplifying lamp change. In order to make the Series Q so versatile (it holds 22 different lamps or elements, and has multiple output ports), the housing was designed as a modular enclosure. The heart of the enclosure is the Series Q, which is a shell with an X-Y-Z adjustable lamp base. Z travel is ±0.075 inch (±2.0 mm). To turn it into a functional lamp housing, simply add the necessary lamp mounting hardware and condensing optics. It uses natural convection cooling to maintain a stable output. External X, Y, Z lamp adjusters allows for placement of the arc, simplifying fiber and slit illumination. An adjustable reflector collects the lamp\'s back radiation, increasing output by up to 60%. A second condenser and a second reflector assembly to can be added to the Series Q, to illuminate two targets simultaneously. Place a different bandpass filter on each output and two different light outputs now exist.

Simultaneously Illuminate up to Four Samples

The 60000 Series Q Housing has four ports. You can mount one condenser and plug the other ports, or use condensers an all available ports (depending upon the lamp) to simultaneously illuminate various targets. The radiating arc or filament of some lamps limit the number of “sides” from which you can collect radiation. With arc lamps and IR sources, you can produce four output beams; with QTH lamps, two output beams; and with deuterium lamps, one output beam.

Which Condenser Lens Is Necessary?

Various condensers lens assemblies are offered; they differ in the lens material, F/# and collection efficiency. All condensers are the 1.5-Inch Series size. Most of the condensers produce a 1.3-inch (33 mm) diameter collimated beam although condensors which produce a focused spot are available as well. Typical spot sizes are listed in the table below. The asphere condensers are corrected optics. Their design ensures that they are corrected for spherical aberration and minimize lateral chromatic aberration.

60005 Rear Reflector

The 60005 is a broadband reflector mounted to an adjustable plate that fits in any of the Series Q ports. Mount it to the port opposite a condenser to collect the radiation from the back of the lamp and focus it near the lamp arc or filament, for collimation by the condenser (Fig. 2) (Tthis is most useful for arc and quartz tungsten halogen lamps). The reflector has external X-Y-Z adjustment knobs for tilt and focus.

Mounting

The Series Q Housings have four leveling feet. The feet allow 0.63-inch (16 mm) height adjustment. To mount the housing directly to inch (1/4-20) or metric (M6) optical tables, remove the feet and use the appropriate mounting holes. This puts the optical axis at 5 inches (127 mm) above the table surface.

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.
