Using the LS-1
Warning
Do NOT insert plastic or flammable materials into the 3 mm filter slot on the top of the LS-1. These
materials could melt or ignite due to the extreme heat generated by the light source.
The light source becomes extremely hot during operation and does not feature a cooling fan. Handle
with extreme care during operation.
Connecting the LS-1
Follow the instructions below to connect your LS-1 light source:
1. Plug the 12 VDC power supply into a standard wall outlet.
2. Plug the 12 V output end of the power supply into the back of the LS-1.
3. Connect a fiber to the SMA 905 connector on the LS-1.
4. Switch the lamp on using the silver On/Off switch on the rear of the LS-1 and allow the lamp to warm up
for approximately 30 minutes.
The LS-1 is now ready to be connected to your sampling system.
Installing the Blue Filter or Teflon Discs in the LS-1
The BG-34 filter and Teflon disc can be permanently installed into the LS-1 to further optimize your experiment.
The BG-34 filter amplifies the blue region in relation to the other regions in the spectrum, while the Teflon discs
diffuse the light emitted from the LS-1. A BG-34 transmission graph can be found at the end of this manual.
Follow the instructions below to install the BG-34 blue filter or Teflon discs into the LS-1:
Note: This procedure involves opening the LS-1 light source. Before opening, ensure that the lamp has been off
long enough to allow the unit to cool and disconnect the power supply from the LS-1.
1. Remove the two black hex bolts (located on either side of the silver On/Off switch) using a 3/32 Allen
wrench (not included). Keep these bolts nearby.
2. Turn the LS-1 over and use the 0.050” Allen wrench included with the LS-1 to loosen the small silver
screw located directly in the middle of the front portion of the lamp, directly between the heat fins of the
LS-1.
3. Separate the two halves of the LS-1 by gently pulling them apart. Ensure that you the wires of the LS-1
are not caught and that the unit separates easily.
4. Insert the BG-34 filter or Teflon disk you wish to install into the ½” counter bore on the inside of the front
half of the LS-1 (where the silver lamp tube resides when the lamp is assembled). Ensure that the disk
lays flush against the bottom of the ½” counter bore.
When inserting the T-shaped Teflon plug, insert the narrow end first.
5. Replace the silver lamp tube, ensuring that it is fully inserted into the ½” counter bore. Verify that the
black wire that connects to the bulb is still connected.
6. Hold the silver lamp tube in place and re-insert the small silver screw that you loosened in Step 2. This
fastens the silver lamp tube in place.
7. Re-attach the two sides of the LS-1, ensuring that the lamp is fully connected.
Note: If you cannot fully reconnect the LS-1 due to the installed filter, you may need to gently move the
black capacitor in the rear half of the LS-1 out of the way until the halves properly connect.
