4. When you want to control the MINI-D2T through OOIBase32 Spectrometer Operating Software, select or
deselect the Strobe Enable box in the Acquisition Parameter dialog bar above the graph area to turn the light
source in the MINI-D2T on and off.
5. 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 could take up to 60 seconds to ignite.
6. 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 MINI-D2T. 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 MINI-D2T.
Disabling the Deuterium Bulb
It is possible to enable or disable the deuterium lamp. Jumper block JA of the MINI-D2T'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 as well. Jumper block JB of the MINI-D2T'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
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. Solarization is the loss of 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.
Replacing the Bulbs
The deuterium and tungsten bulbs cannot be replaced by unauthorized personal. To replace a bulb in the MINI-D2T,
contact Ocean Optics.
