the lamp. First, the heater in the deuterium lamp ionizes the available deuterium. At this point, the
yellow Heater On light on the front panel will light. After ~30 seconds, the red UV On light located at
the top of the front panel will light. (The Heater On light will turn off at the same time.)
7. To turn off the deuterium lamp, press the white UV Off button located on the front panel. The red UV
On light should go out.
Operating the Tungsten-Halogen source
8. To power the tungsten-halogen lamp, push in the white button labeled Visible On. The red Vis. On
light will come on.
9. To turn off the tungsten-halogen lamp, press the white Visible On button located on the front panel.
The red Vis. On light will go out.
Bulb Replacement
Replacing the Deuterium bulb
1. Order a deuterium replacement bulb, item DT-1000-BD, from Ocean Optics.
2. Make sure the DT-1000 is turned off, the power cord is disconnected, and the source has cooled.
3. Use a Phillips-head screwdriver to remove all 12 screws from the side panels of the DT-1000 casing.
Do not remove any screws from the front, back, or bottom panels. Remove the cover.
4. Locate the deuterium bulb. It is located at the front of the housing, mounted on a black platform. Three
wires lead from the bottom of the bulb to the green electronic board: one red wire and two black wires.
5. Use a Phillips-head screwdriver to loosen the screws securing these three wires to the green electronic
board. Once the screws are loose, gently remove the red wire and the two black wires. You do not need
to completely remove the screws to detach the wires. (Note that on the green electronic board, just to
the right of each wire, is a letter. To the right of the red wire is the letter “A”. To the right of one black
wire is the letter “H” and to the right of the second black wire is the letter “C”.)
6. Use a Phillips-head screwdriver to remove the two screws securing the bulb to the black platform.
7. Remove the old bulb unit.
8. Inspect the new bulb unit, but avoid touching the glass casing (or envelope) around the bulb, as the
oils from your skin will deteriorate the bulb. Inside the envelope is a triangle-shaped filament. The
filament has a square opening. The light passes through the square opening to the collimating lens.
Take the new bulb, carefully feeding the three wires through the hole in the black platform, and
position it so that the square opening in the filament faces the collimating lens.
9. Screw in the two screws that secure the bulb to the black platform.
10. Secure the three wires to the green electronic board. Attach the red wire to the top screw, labeled “A”.
Attach the black wires to the screws on the board labeled “H” and “C”. It does not matter which
black wire is attached to screw “H” or “C”.
11. Put the DT-1000 casing back on and secure it with the 12 screws.
Replacing the Tungsten-Halogen bulb
1. Order a tungsten-halogen replacement bulb, item DT-1000-BT, from Ocean Optics.
2. Remove all 12 screws from the side panels of the DT-1000 casing using a Phillips- head screwdriver.
Do not remove any screws from the front, back, or bottom panels. Remove the cover.
3. Locate the tungsten-halogen bulb. It is inserted on the top of a cylindrical unit held by a set screw in a
hole in the black platform. The cylindrical unit is positioned behind the deuterium bulb. Two thin wires
lead from the bottom of the unit to a socket on the electronic board.
4. Gently grip the top of the bulb and pull it away from the cylindrical unit. Discard the bulb.
5. Insert the new bulb into the top of the cylinder, being careful to position the bulb’s pins over the holes
in the top of the cylinder.

The cylindrical unit is held in place with a small set screw. By loosening it, the user can slide the
bulb unit up and down, positioning it in front of the attenuator, a metal disc that attenuates the light
before going through the collimating lens. Another set screw holds the attenuator in place.
6. Put the DT-1000 casing back on and secure it with the 12 screws.
For directions on adjusting the focus of the collimating lens on the DT-1000, turn to Appendix A .
