CYCLIC OPERATION AND LIFETIME
The continuous operating life of a FiberLight D2 deuterium lamp exceeds 1000 hours. As electrodeless discharge lamps (EDL) with high frequency excitation come into use, FiberLight D2 can be switched on and off on demand and operated in cycles. Due to the fact that the number of ignitions does not have a negative effect on the lamp's lifetime, an extended service life of up to three years can be achieved. Additionally pulse-to-pulse repeatability is extremely consistent to within 0,1%.
INSTANT ON AND STABILITY
The FiberLight D2 EDL ignites instantly and therefore delivers an immediate stable light output. This feature makes it unique among UV light sources. FiberLight D2 is therefore the ideal light source in analytical instrumentation for waste water analysis and other pollution monitoring, where light absorption is measured for only a few seconds and repeated after long intervals. Consequently the lamp would be switched on only for the short measurement time, while it would remain turned off for most of the time.
APPLICATION EXAMPLE
To determine the nitrate content in waste water, FiberLight D2 is switched on for the duration of ten seconds to measure the nitrate light absorption. This procedure is repeated every 300 seconds. Measurement consistency is extremely good and the lamp's lifetime can be extended up to three years under these operating conditions.
