FiberLight® ^D2 Portfolio

UV-Vis Light Source for high measurement consistency

FiberLight^® D₂ is a compact UV-Vis light source designed for mobile spectroscopy applications and all types of handheld devices that require a low power consumption. It has a continuous spectrum covering the whole range from vacuum UV to near Infrared.

The FiberLight^® D₂ System is a complete UV-Vis light source, combining a deuterium lamp, with a 0.25 Watt tungsten lamp, a shutter, optical system and a SMA 905 connector. All elements are mounted on a printed circuit board. Both lamps and the shutter can be separately controlled by a TTL signal. FiberLight requires an external 12 VDC / 600 mA supply.

It is the only light source on the market with such a small size, integrated power supply and a smooth spectrum in the whole UV-VIS range. FiberLight^® D₂ is easy to integrate and handle. With the flexibility of the product and design Noblelight can meet the customers’ needs.
