Fiber coupled LED light source UV-VIS-NIR

The fiber coupled LED light source that is essential in every university, laboratory, research centre or I+D department. COB has been designed and developed by PYROISTECH for the every day tasks. It is a LED light source that stands out for being silent, compact and with a design that will not be missed. COB has been optimized in order to maximize the power coupled into the optical fiber and counts with a wide range of configuration options, suitable for fluorescence measurements, absorption, transmission or colorimetry, and with applications in education, engineering, chemistry or biology.


  • From 270 nm to 940 nm. UV-VIS-NIR
  • Operation in continuous or pulsed mode
  • Adjustable power in both modes
  • Output connector: SMA or FC
  • Stable in the whole spectral range
  • Compact (10.5 x 11.5 x 8cm)
  • Light (500 g)
  • Silent (no fan required)
