Components
Draw Tower Bragg Gratings
Temperature and strain sensors
These fibre Bragg Gratings arrays are perfectly suited to be used as thermal or strain sensors. The Bragg Grating arrays are inscribed in the fibre directly during the draw. This process allows to preserve the fibre’s initial mechanical strength, as if no grating had been inscribed. Thus, we can inscribe as many gratings as required in the fibre in a repeatable manner.
