8. Lift up the black protective shutter and disconnect your optical fiber from the SMA connector.
9. Replace the red plastic cap over the SMA connector.
Bulb Replacement
1. Order a replacement bulb, item D-1000-B, from Ocean Optics.
2. Make sure the D-1000 is turned off, the power cord is disconnected and the lamp has cooled.
3. Use a Phillips-head screwdriver to remove all 12 screws from the side panels of the D-1000 casing. Do not
remove any screws from the front, back, or bottom panels. Remove the cover.
4. Find 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 electronic board: one red wire (with a time indicator) 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 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. In order to remove the bulb, you will need to unscrew the nut holding the collimating lens and SMA connector
in place. It is positioned in such a way that if the nut remains in place, you will not be able to take out the
deuterium bulb. Use a 3/8” wrench to remove the nut.
7. Use a Phillips-head screwdriver to remove the two screws securing the bulb to the black platform.
8. Remove the old bulb unit. 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.
10. Screw in the two screws that holds the bulb to the platform and the nut that holds the collimating lens in place.
12. 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”.
13. Put the D-1000 cover back on and secure it with the 12 screws.
For directions on adjusting the focus of the collimating lens on the D-1000, turn to Appendix B .
