USB-DT Deuterium Tungsten Halogen Source

Most Versatile Lamp We Offer

The USB-DT Deuterium Tungsten Light Source is a compact source about the size of a deck of cards and provides stable, broadband output from 200-2000 nm. The USB-DT is our most versatile combination UV-VIS light source because you can control the several lamp functions via software and because of the many ways in which the lamp can be used in a measurement setup.

Software Control

When the USB-DT is stacked with the USB4000 or USB200+, or used with an HR4000, HR2000+ or QE65000 and the Breakout Box, you can control the following lamp functions through software:

adjusting the intensity of the tungsten source
activating the internal shutter to block the light path
controlling on/off switch of each source independently
utilizing a low-power shutdown mode
saving settings in memory

Stack with the USB Series Spectrometer

The USB-DT can be set up in a variety of ways. It can be stacked with a USB4000 or USB2000+ with the USB-ADP-DT2 connector. (The USB-ADP-DT2 is not included with the purchase of a USB-DT). Though the USB-DT can be stacked with the USB4000, it is not the kind of direct-attach source that eliminates fibers; the USB-DT requires fibers as well as a simple 5-volt wall transformer for power (included).

Stand-alone Source

The USB-DT allows you to use the lamp as a stand-alone light source with any Ocean Optics spectrometer. The USB-DT has a 15-pin connector for interfacing to the spectrometer. In the absorbance setup at right, the USB-DT provides light for a cuvette. However, when not interfaced electronically to a spectrometer, you cannot control its lamp functions via software.

Novel Deuterium Tungsten Halogen Sources

Our deuterium tungsten halogen sources combine the continuous spectrum of deuterium and tungsten halogen lamps in a single optical path. These combined-spectrum sources produce stable, continuous UV-VIS output that make them ideal for applications such as absorbance spectroscopy.
