Light Sources: DT-1000 Deuterium Tungsten-Halogen
Light Source
The DT-1000 D EUTERIUM T UNGSTEN -H ALOGEN L IGHT S OURCE combines the continuous spectrum of a
deuterium UV light source and a tungsten-halogen VIS/Shortwave NIR light source in a single optical path.
The combined light source produces a powerful, stable output from ~200-1100 nm. It also has a highly
stabilized microprocessor-based power supply designed for optimum stability.
Parts Included
•
DT-1000 Deuterium Light Source
•
Safety eyewear for protection against dangerous ultraviolet radiation
•
Power cord for connecting DT-1000 to outlet
•
Allen wrench for adjusting the focus of the collimating lens
Caution!
.
! The beam emerging from the DT-1000 produces visible light and/or invisible ultraviolet radiation.
Direct contact with the beam could cause serious eye injury. Safety eyewear must be worn at all times
while operating the DT-1000. Do not remove any safety device installed.
!
Dangerous voltages present.

For optimum performance below 230 nm, use a solarization-resistant fiber with this lamp.
Operation
Allow several minutes for the lamp to warm up and for the power to stabilize, regardless of the bulb being
used. Best results are obtained after 30 minutes. The spectral output as delivered by an optical fiber will
decrease significantly at wavelengths lower than 230 nm due to attenuation in the lamp envelope, the
decrease in detector efficiency in the spectrometer, and attenuation by the fiber.
1. Put on safety eyewear.
2. Lift the black protective shutter covering the fiber optic port. Install an optical fiber. (For best results,
use our solarization-resistant fibers.)
3. Plug the power cord into the rear of the DT-1000. Plug the other end into a 110 VAC outlet.
4. To turn on the power for the DT-1000, flip the power switch at the rear of the unit, just above where the
power cord connects to the DT-1000. When the power is on, the green Power On light located at the
bottom right of the front panel will light. At this time the user can now power up the deuterium or
tungsten-halogen source or both. (See
Operating the Deuterium source and Operating the Tungsten-Halogen
source.) To turn off the DT-1000, both deuterium and tungsten-halogen sources must be off first. Only
then can the user flip the power switch at the rear of the unit to the off position. The green Power On
light will turn off.
5. Lift up the black protective shutter and disconnect your optical fiber from the SMA connector.
Operating the Deuterium source
6. To power the deuterium lamp, push in the UV Start button located on the front panel. This white
button turns on the deuterium lamp. Pushing in the UV Start button initiates the start-up sequence for
