66080 Deuterium Source


Fig. 1 Spectral irradiance of deuterium lamps (UV portion of the spectrum, only).



Choice of Five Lamps

The 66080 includes your choice of one of the lamps listed in Table 1. The high irradiance lamps have a very small arc; they are useful for fiber illumination. The ozone free models are safer alternatives, if you don't need the very short wavelengths. Please note, the “ozone free” lamps still produce some ozone, but at a significantly lower rate.

Table 1 Deuterium Lamps
 Lamp Type  Spectral Output (nm)  Arc Diameter (mm)  Model
 High Uniformity, Ozone Free  180 - 500  1.0  63161
 High Uniformity, Full Spectrum  160 - 500  1.0  63162
 High Irradiance, Full Spectrum  160 - 500  0.5  63163
 High Irradiance, Ozone Free  180 - 500  0.5  63164
 High Irradiance/ Stability, Ozone Free  180 - 500  0.5  63165


Lamp Housing

The lamp housing is our popular Series Q. An F/1.5 condenser made from UV grade fused silica collects and collimates the lamp's radiation. Output is a 1.3 inch (33 mm) diameter beam. You can focus it to a tight spot for fiber or monochromator illumination by using a secondary focusing lens assembly.

Power Supply

The 66080 Source uses the 68942 Power Supply. The 68942 was designed for simplicity, economy, and size. It runs the lamp at a fixed 300 mA current. The only control is the power on/off switch. Two LEDs indicate status.

Mounting

The Series Q Housing has four leveling feet for free standing use. The height is adjustable by 0.50 inches (12.7 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

Deuterium lamps emit dangerous levels of UV radiation. Ensure that only authorized personnel are in the vicinity of the source, and wearing UV protective eyewear, clothing and gloves. Lighted UV warning signs, posted outside laboratory doors where UV sources are operating, can prevent accidental exposure.

We also recommend using an electronic shutter to block the beam when the source is not in use. Or, keep the beam contained by using beam tubes or fiber optics to carry it to your target.

If you do not require output below 180 nm, choose an ozone free lamp. For DUV work, vent the ozone to the outside or use an Ozone EaterTM.
