FJORD
The SLED broadband NIR source
FJORD is the SLED broadband light source designed and developed by PYROISTECH to provide a personalized spectral response in the NIR to the applications of the most demanding users. It exists the possibility of combining up to 8 modules to choose from high power SLED, and including in addition to this the option of adding an extra module to control the power of each SLED individually. Its compact, silent and sturdy design allows its integration in whatever type of application, covering a wide range of possibilities, from optical laboratories, fiber optics testing, Bragg grating interrogation, tomography, or industrial sensors among others.

Examples of application
LPFG inscription monitoring
In this setup, LPFG interrogation is performed using a FJORD broadband light source as excitation at the input of the fiber and collecting the optical power at the output using an optical spectrum analyzer. The analyzer permits to measure the resonant wavelength location and the band attenuation.

ºBrix measurement
The figure on the left shows a setup with a FJORD broadband light source for interrogating an optical fiber refractometer for ºBrix measurement. This refractometer consist of an indium tin oxide (ITO) coated D-shaped optical fiber.
