These sources provide visible and near infrared radiation with minimal ultraviolet. These light sources are widely used for radiometric and photometric applications, and as visible excitation sources.
Why a Series Q QTH Source?
The Series Q Lamp Housing is what makes these systems so versatile. Two output ports allow simultaneous illumination of two samples. The 60000 Series Q has four output ports, but because of the asymmetrical filament of our QTH lamps, you can efficiently collect light only from the front and back of the lamp. The housing has X, Y, Z lamp adjusters letting you accurately position the filament for optimum light collection. It uses natural convection cooling so it’s quiet and stable! These sources only include one condensing lens assembly. For multiple outputs, order additional condensing lens assemblies.
What Makes Up A Series Q Arc Lamp Source?
These sources come with everything you need to begin operation. They include the following:
- Model 60000 Q Series Housing with one condenser, rear reflector, and X, Y, Z lamp position adjusters
- Model 68938 Power Supply
- Your choice of lamp and appropriate lamp socket adapter
- All necessary cables and mounting hardware
60000 Series Q Lamp Housing
The 60000 is a versatile, protective enclosure for low wattage QTH lamps. External, high resolution controls allow ±0.13 inch (±3.3 mm) lamp adjustment in the X, Y and Z directions. We include one condenser and one rear reflector to collect the lamp's back radiation. You can replace the reflector assembly with a second condenser for the simultaneous illumination of two samples.
Power Supply
The 68938 is a highly regulated Power Supply. This constant current source maintains a stable lamp output and minimizes light ripple.
Interchangeable Lamps
Switch between the following lamps, mounted either horizontally (H) or vertically (V), by simply changing the socket adapter.

Which Source Should I Choose?
We offer four QTH Sources; the difference is the condenser on the housing. We compare the condensers in Table 2.

Horizontal or Vertical Operation?
Fig. 1 shows the filament dimensions and configuration of our 10 to 100 W QTH Lamps. If you are using one of these sources as a fiber illuminator, and you want to image the filament onto the input of a fused silica fiber slit, use the F/2.2 condenser.
Fig. 1 You can operate these lamps in a vertical or horizontal orientation.
Mounting
The Series Q Housing has 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
QTH lamps emit UV radiation that may be hazardous. We recommend that you wearUV protective glasses or goggles, and gloves when working with these sources for UV safety equipment).
