Tungsten halogen lamp light source FiberLight® D2

deuterium lampVISultraviolet

Overview
The FiberLight D2 lamp system is a compact UV-Vis light source that combines a deuterium lamp and a 0.25 W tungsten lamp to deliver a continuous spectrum from vacuum UV to near-infrared. It is designed for mobile spectroscopy and compact or handheld instruments where low power consumption, fast switching and simple fiber coupling are required.

Detailed description
The FiberLight D2 System integrates a deuterium lamp, a 0.25 W tungsten lamp, a shutter, an optical assembly and an SMA 905 output on a single PCB. Both lamps and the shutter are controllable independently via TTL signals. The unit requires an external 12 VDC / 600 mA supply. Its PCB-mounted design, low heat dissipation and instant ON/OFF stability make it suitable for space-constrained, portable or battery-driven instruments.

Features

• Compact footprint for integration into small instruments
• Low power consumption (external 12 VDC / 600 mA)
• Instant ON/OFF with rapid spectral stability
• Cyclic operation capability
• Extended service life up to approximately 3 years
• Independent TTL control of deuterium lamp, tungsten lamp and shutter
• Easy coupling to optical fibers, flow cells and capillaries
• Low thermal load on the host instrument

Applications

• Laboratory UV-Vis spectroscopy
• Environmental monitoring: water quality, wastewater analysis, marine chemistry, biological measurements, air quality
• Process control and inline analysis
