Heraeus Noblelight has released FiberLight L3, a broadband UV LED light source module for analytical measurement instruments combing the benefits of LED technology with broadband UV spectral output.
Broadband spectral output is desirable for optical analytical instruments because it provides the flexibility to perform both qualitative and quantitative analysis with one instrument. FiberLight L3 will find immediate application in instruments used for environmental monitoring such as air and water quality, and soil monitoring, and also for protein purification.
OEMs, such as those manufacturing UV-spectrophotometers, flash chromatography can integrate the FiberLight L3 more easily into their analytical instruments due to its small form factor and lower optical setup costs. As a result, analytical instrument OEMs can develop new portable and handheld instruments more quickly and deliver their instruments to a broader range of customers.
The FiberLight L3 uses a single UV-LED chip and phosphors to produce the broadband output, overcoming many disadvantages of previous approaches that used multi-chip UV LED arrays.
FiberLight L3 provides broadband UV spectral output from 250 to 490nm and a lifetime of more than 5,000 hours. Power consumption is less than 1.5W with excellent optical stability. The module incorporates the optical fibre coupling and can operate in pulsing or continuous modes.
