Complete Systems |
We offer complete D2 Systems, which use the Series Q Lamp Housing and our Apex Illuminator. You can also build your own system by selecting the components listed below. |
Power Supply |
The 68942 is a simple, low cost supply that runs any of these deuterium lamps, at the rated 300 mA. The 68840 is a current adjustable, fully featured model. |
Lamp Housings or Rod Mounts |
You can run a deuterium lamp in an open-air rod mount or in an enclosed lamp housing. We describe the options below: |
|
This housing has a condensing lens assembly that collects and collimates the lamp’s radiation. Output is a 1.3 inch (33 mm) diameter beam (see Series Q Lamp Housings). |
Dual Source Monochromator Illuminators |
The 7340 Series of Illuminators hold two sources simultaneously; output is from one source at a time. The output is a focused spot matched to our monochromators (see 7340 Series Monochromator Illuminators). |
Single Source Monochromator Illuminators |
The Apex family of Monochromator Illuminators are fully integrated packages (power supply is built into lamp housing) matched to our monochromators (see Apex Monochromator Illuminators). |
|
The 66145 is an inexpensive rod mounted holder. It runs the lamp in open air. Because of the dangerous UV radiation emitted by these lamps, we suggest that you use the 66145 as part of an enclosed system. |

Which Model Do I Choose |
Choose a lamp first by the shortest wavelength you need. If you aren't working below 180 nm, choose an ozone free lamp. (Please note, “ozone free” means reduced ozone.) The high irradiance lamps have a very small, 0.5 mm, arc; they produce both the highest irradiance and highest radiance, but are also more expensive than the high uniformity lamps. |
Construction |
Deuterium lamps are arc lamps filled with deuterium, at low pressure. Deuterium lamps emit only from one side and in one direction, unlike arc lamps, which radiate in all directions. Collection is therefore easy and efficient. The window material determines the DUV output of the lamp. Ozone free models use UV Glass, which does not transmit below 180 nm. |
Safety Considerations |
Deuterium lamps emit high intensity ultraviolet radiation. Always use protective eyewear, clothing, and gloves when working in the vicinity of these lamps. |
