FiberLight is a compact UV-Vis light source designed for mobile spectroscopy applications and all types of handheld devices that require a low power consumption UV-Vis light source. FiberLight has a continuous spectrum covering the whole range from vacuum UV to near Infrared.

The FiberLight System is a complete UV-Vis light source with a shine-through design deuterium lamp, a 0.25 Watt tungsten lamp, shutter, optical system and SMA 905 connector. All elements are mounted on a printed circuit board driven by an external 12 Vdc/600 mA power supply. Both lamps and the shutter can be separately controlled by a TTL signal.

FiberLight is powered from an external supply; this makes it an ideal light source for applications with limited space in the instrument, portable instruments or battery- operated equipment. Its small dimensions and ease of operation open up new possibilities for instrument designers.

Spectral Distribution of FiberLight
The spectral emission covers the entire range from 200 nm to 1,100 nm; optional extended range from 185 nm to 1,100  nm.

HighPower  FiberLight
A 10W High Power FiberLight version is now available, offering double UV light output and similar compact size.Higher power means shorter integration time for faster response and lower detection limits; while still small size suitable for portable operation.

Lifetime and Cyclic operation
The guaranteed continuous operating life of a FiberLight deuterium lamp is more than 1000 hours. As the lamp is an Electrodeless Discharge Lamp (EDL) with high frequency excitation, it can be switched ON and OFF on demand and can be operated in cycles. The cyclic lamp operation results in an extended service life of up to three years. As an EDL, the number of ignitions does not reduce lifetime. In addition, pulse-to-pulse repeatability is extremely consistent to within 0.1 %.

Instant ON and Instant Stability
FiberLight EDL is the only deuterium lamp that can be switched instantly ON and instantly deliver a stable light output. This feature makes it unique among UV light sources. FiberLight is therefore the ideal light source in analytical instruments for pollution monitoring, where light absorption is measured for only a few seconds
and repeated after long intervals. In such monitoring, FiberLight is switched ON only for the short measurement time, while it is OFF for most of the time. Nevertheless,
measurement consistency is extremely good because of its pulse-to-pulse repeatability.

Application Example
To measure nitrate content in waste water, FiberLight is switched ON for 2 seconds to measure the nitrate light absorption, and the measurement is repeated every 60 seconds. Measurement consistency is extremely good and under these operating conditions, lamp lifetime can be extended up to 3 years.
