R-LS-1 Rack-mount Tungsten Halogen Light Source
The R-LS-1 Rack-mount Tungsten Halogen Light Source is a white-light source optimized for the VIS-NIR (360-
2000 nm) range. It offers high color temperature, highly efficient output and long life in a compact, economical
package.
Standard R-LS-1 light sources come with a 900-hour 3100 K bulb. However, the LS-1-LL (long life) is identical to
the LS-1 with the exception of its 10,000-hour 2800 K bulb.
The R-LS-1 is the rack-mount version of the LS-1. It is identical in performance to the LS-1.
Parts Included
The R-LS-1 light source ships with the following items:
•
R-LS-1 Rack-mount Tungsten Halogen Light Source
•
Allen wrench
•
Three Teflon
diffusion discs
•
One BG-34 blue filter
•
12 VDC power supply (a European power supply is also available)
The Teflon
diffusion discs are installed inside the light source. They are used to create a diffuse light source that
is optimal for coupling into fibers, as well as for attenuating the source when spectrometer saturation is an issue.
From smallest to largest, the three Teflon
discs attenuate the light by approximately 50%, 75%, and 99%
respectively.
The BG-34 blue filter is a 12.7 mm filter that you can install in the light source to enhance the signal in the blue
region relative to the red and NIR regions.
See the Using the R-LS-1 section that follows for more information.
Using the R-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. Handle with extreme care.
Connecting the R-LS-1
Follow the instructions below to connect your R-LS-1 light source:
1. Identify the R-LS-1 in the equipment rack.
2. Connect the 12 VDC power supply to a wall outlet.
3. Connect the barrel connector on the power supply to the rear of the R-LS-1.
4. Connect a fiber to the SMA 905 connector on the R-LS-1.
5. Switch the lamp on using the silver On/Off switch on the R-LS-1 and allow the lamp to warm up for
approximately 30 minutes.
The R-LS-1 is now ready for operation in your sampling system.
