    Data Sheet FiberLight
    The miniature UV/vis light source for spectroscopy and on-line process analysis
     
    FiberLight is a very compact light source for the ultraviolet, visible and near infrared spectral range (from 200 nm to 1100 nm). The heart of FiberLight is an electrode-less RF induced deuterium lamp or line source.
     
    The miniature lamp opens up UV spectroscopy to portable, battery operated instruments. Application examples are organic chemistry, pharmaceuticals, petrochemicals, agriculture, the environment and life science for on-site analyses and diagnosis. Another area of applications is in small instruments for on-line process analysis.
     
    FiberLight is a complete UV/vis light source. It consists of the lamp unit, with deuterium and tungsten lamps in shine-through array, shutter and optical coupling with SMA fiber optic connection. There is also an optional version without optical fiber connector for direct illumination of the measurement cell. All elements are mounted on a circuit board and are externally controlled through TTL signals. FiberLight can be operated with a 12Vdc/0.6A power supply.
