Light Sources: LS-1 Tungsten Halogen Light Source
The LS-1 T UNGSTEN H ALOGEN L IGHT S OURCE is a versatile, white-light lamp utilized for the VIS-
Shortwave NIR (360 nm-2
µ
m). The lamp, with either a 900-hour or 10,000-hour bulb, offers high color
temperature and extremely efficient output.
Parts Included
•
LS-1 Tungsten Halogen Light Source
•
12 VAC power supply
•
Allen wrench for adjusting the collimating lens
Caution!
!
The LS-1 becomes HOT during operation. No cooling fan is installed in the LS-1. Handle with care.
!
DO NOT insert plastic or flammable materials in the filter slot. The materials could melt or ignite.
!
The unit could ignite flammable materials that come in contact with the metal housing.
Operation
Turning On the Lamp
1. Plug the wall transformer end into a standard 110 V outlet. Plug the 12 V output end into the back of
your LS-1.
2. Screw a fiber into the SMA connector on your LS-1.
3. Find the on/off switch on the back of the lamp and turn the lamp on. Allow the lamp to warm up for
approximately 30 minutes.
Using the Filter Slot
The slot between the lamp and the fiber coupler can be used to hold filters or light blocks. You can place a
filter into the filter slot; however, be aware of the following:
•
The filter slot accepts filters up to 3 mm thick.
•
Because the lamp can become hot, avoid plastic filters as they may melt.
•
The unit could ignite flammable materials that come in contact with the metal housing.
•
There is no filter clamping screw for holding filters in place.
The most useful filters include the following:
•
an FG-3 blue filter for increasing the relative energy near 400 nm and 800 nm compared to 600 nm
•
an IR cutoff filter to reduce stray light below 750 nm
•
a 550 nm long pass filter to eliminate second-order effects on Shortwave NIR measurements
Replacing the Bulb
1. Order a replacement bulb (LS-1-B for a 900-hour bulb or LS-1-LL-B for a 10,000-hour bulb).
2. Turn off the LS-1 and allow the lamp to cool.
3. Use an Allen wrench to loosen the set screw on the bottom of the lamp. You do not need to remove the
set screw. This screw holds the bulb in place.
