Important Safety Notices
1. Never look directly into the light beam, including through the cooling fan while the light
is on, as this can cause eye damage.
2. Do not remove or modify any installed safety devices on this equipment. Doing so will
void your warranty and create an unsafe operating environment.
3. Do not use the unit if it is damaged in any way. Contact your dealer for repair or
replacement information.
Warranty and Liability
This SP’s product is warranted against defects in material and workmanship for one year from
the date of shipment. During the warranty period, Spectral Products will, without charge, repair or
replace, at its discretion, the defective product, or components/parts.
This product must be returned to a service facility designated by Spectral Products (SP) for
warranty service or repair. For products returned under warranty, the Buyer shall prepay shipping
charges (including shipping charges, duties, and taxes for products returned to SP from another

Spectrum
The deuterium (D2) lamp is designed for use in spectroscopic applications where high intensity
and stability in the 190 to 400nm band are needed. Above 400nm, some spiky spectra will be detected
also.
The Tungsten-halogen light source is a well-known near-black body radiation source. Its
spectrum is also very similar to those of black body radiation.

The envelope of tungsten-halogen lamps is made of fused silica. The transmittance of fused
silica, therefore, needs to be considered.

Operation
Front Back
Component
Description
Power terminal
input
Connects power cable to provide voltage to our deuterium and high power tungsten-
halogen hybrid light source. One main power supply provides the input voltages on
both lamps.
Power switch
There are three on/off power switches on the light source. One is the main power
switch that is located on the front side. The other two are for the deuterium and the
tungsten-halogen, which is located on the backside.
Note: It takes ~20-30 seconds to warm up the deuterium power supply so the
deuterium light doesn’t come on immediately when the deuterium power switch turns
on. If the tungsten-halogen is on while turning on the deuterium, the tungsten-halogen
light can blink several times.
Fuse
Contains the fuse to protect the unit against overload.
Fuse type:
For main 24V power supply: 5A/250V
For deuterium relay power supply: 2A/250V
Cooling fan
Cools the interior of the light source housing.
Note: Do not look at the light beam through this fan, especially when the deuterium is
on.
Output
SP can provide SMA905 or FC. SMA is the default connector.
The tungsten-halogen light is much stronger than the deuterium light in general. The
balanced output version, ASBN-DW-F-BAL, will be adjusted the tungsten-halogen
output signal at SP based on SP’s CCD spectrometer for the 200-1100nm range.

Bulb Replacement
Replacing the Deuterium lamp bulb
1. Turn off all power.
2. Wait until the lamp cools down.
3. Remove housing.
4. Remove heat shield.
5. Take off the three deuterium lamp leads on the bottom.
6. Unscrew the screws for the deuterium bulb.
7. Take out the old bulb and replace the new one.
NOTE: When touching the new deuterium lamp, please be careful not to touch it with a bare
hand.

Replacing the Tungsten-Halogen lamp bulb
1. Turn off all power.
2. Wait until the lamp cools down.
3. Remove 4 faceplate screws.
4. Pull out the light source slider.
5. Remove the top 2 set screws from the bulb holder.
6. With finger cots, remove the (0.35-inch) set screw on the bulb holder.
7. Carefully pull apart the holder into its 3 distinct pieces and replace the bulb.
Sometimes, the bulb may pull the plug with it, so please be careful when handling it. If this
occurs, insert the new bulb into the plug and insert both pieces into the holder.
8. Put pieces back together, in the direction of the reference photo.
9. Insert the set screw on the holder. Tighten firmly.

10. Place the holder back on the light source mount and tighten the 2 set screws on the
mount.
NOTE: All the optical components were properly aligned by SP. Do not touch any mounting
screws. Adjust the bulb itself when aligning the filament position.
