There can be up to a 1.5 second delay between turning the bulbs on via the software and the
bulbs igniting. If the lamp has not been used recently, the deuterium bulb may take up to 60
seconds
3. For 0.3% peak-to-peak stability, allow 30 minutes warm-up time before taking your
measurements.
Disabling the Tungsten or Deuterium Bulb
It is possible to disable the deuterium or the tungsten bulb in the ISS-UV-VIS. Both bulbs are enabled
at the time of manufacture. In order to disable the deuterium or tungsten bulb, you must remove the
casing of the ISS-UV-VIS.
Disabling the Deuterium Bulb
It is possible to enable or disable the deuterium lamp. Jumper block JA of the ISS-UV-VIS's circuit
board controls the deuterium bulb.
 Short pins 2-3 (that is, place a jumper over pins 2-3 of JA) to enable the deuterium bulb.
 Short the pins 1-2 (that is, place a jumper over pins 1-2 of JA) to disable the deuterium bulb.
Disabling the Tungsten Bulb
It is possible to enable or disable the tungsten lamp. Jumper block JB of the ISS-UV-VIS's circuit
board controls the tungsten bulb.
 Short pins 2-3 (that is, place a jumper over pins 2-3 of JB) to enable the tungsten bulb.
 Short pins 1-2 (that is, place a jumper over pins 1-2 of JB) to disable the tungsten bulb.
Using Solarization-resistant Fibers
Solarization is the loss of color or transparency in glass due to exposure to ultraviolet radiation. If you
are using a UV light source, the UV radiation degrades the silica in a standard patch cord fiber over
time, resulting in increased overall absorption values and invalid data. This degradation is called
solarization.
Our 300-µm Diameter Solarization-resistant Optical Fiber consists of a silica core, surrounded by a
silica cladding material. The fiber is then coated in aluminum. Our solarization-resistant fibers are best
used for regions below 250 nm, or for applications where exposure to long-term UV light occurs.
Replacing the Bulbs
The deuterium and tungsten bulbs cannot be replaced by unauthorized personal. To replace a bulb in
the ISS-UV-VIS, contact Ocean Optics.
