66924 Arc Lamp Source.

Why These Sources?

Choose one of these systems when you need the flexibility to run mid to high intensity arc lamps. These sources operate 450 to 1000 W short arc lamps with the simple change of a lamp socket adapter. For safety or convenience reasons, they can be remotely operated via your PC (RS 232 interface is standard and IEEE-488 interface is optional). If you have a fixed power application, we offer theSimplicity Series - a more economical choice.

What Do These Sources Consist Of?

These systems come complete with all the necessary components to begin work. These sources include:
  • Lamp Housing with a condenser and a built-in ignitor
  • 69920 Power Supply
  • Your choice of arc lamp and socket adapter
  • All necessary cables and mounting hardware

Lamp Housing

These Universal Housings are rugged aluminum enclosures that hold the lamp, ignitor, rear reflector and condensing lens assembly. Lamp adjusters let you precisely align the lamp and rear reflector for maximum output. Temperature sensors regulate the temperature inside the housing to prevent lamp overheating, and a door interlock prohibits accidental exposure to UV radiation. The lamp will not run if the housing door is open. An integral elapsed time indicator allows the user to monitor lamp useage.


Fig. 1 The rear reflector collects the lamp’s back radiation, adding up to 60% to the total source output.

Power Supply

High wattage lamps demand a reliable power supply. The 69920 is dependable and long-lived, and offers many convenient features for lamp operation, including RS 232 and optional IEEE-488 (GPIB) computer interfaces for remote lamp control and monitoring.

Lamp ignition is safe and easy. Simply connect the two high voltage cables to the lamp housing and plug in the power cord, and you're ready to ignite the lamp. To ensure long term (>8 hours) output stability, use the68950 Light Intensity Controller.

Easily Interchangeable Lamp

These housings are truly universal. Run any of the following lamps by simply changing the socket adapter.

Which Sources Do I Choose?

We offer three condensing lens assemblies. The differences are:
  • Spectral range
  • Beam quality and collection efficiency
  • Output beam size

Table 2 lists the spectral ranges and apertures, and compares the performance of the condensers. The F/0.7 Aspherabs® use four lens elements and therefore offer the highest beam quality; spherical aberration is negligible. They are also the most efficient collectors. Use these plus a secondary focusing lens when you need to reimage the arc.

 Source  Condenser Type  Aperture  Lens Multiplication Factor *  Transmittance Range of Lens Material
(nm)		  Size Series**
 66924  F/1 two element fused silica  1.9 in. (48 mm)  0.11  200 - 2500  2 inch
 66925  F/0.7 four element silica-borosilicate crown Aspherab®  2.7 in. (69 mm)  0.18  350 - 2500  3 inch
 66926  F/0.7 four element fused silica Aspherab®  2.7 in. (69 mm)  0.20  200 - 2500  3 inch

Liquid and Dichroic Filters Protect Other Optics

These sources have a high output power, which can fracture optical filters. If the beam is focused, it can destroy fiber bundles and coatings on optical components. To protect these components use aliquid filter ordichroic filter at the output of the condenser. These will pass the UV and VIS, but remove most of the damaging IR.

Mounting

These housings have four adjustable feet for free standing use. For fixed mounting, remove the feet and fix the housing directly to an inch or metric table or base plate. The optical axis is 7.5 inches (191 mm) above the table.

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 very high intensity UV radiation. Exposure, even for short periods, to ultraviolet can cause severe skin and eye burns. Always wearprotective eyewear, clothing, and gloves when working around these sources, or enclose the beam path.

Ozone is the other UV hazard. If you do not need output below ~260 nm, choose an ozone free lamp. If this is not an option make sure you are in a well ventilated area and exhaust the ozone to the outside with aBlower Kit or use ourOzone Eater™.

All sources include the lamp housing, power supply and your choice of lamp and appropriate socket adapter. Please specify your choice of lamp when ordering a source.
