The FBG Series fiber optic grating is formed by periodically and permanently changing the refractive index of the fiber core with a high power laser irradiation. It features low optical loss and low cost. Our FBG is packaged in athermal material that reduces its sensitivity to temperature variations.   Special package this is sensitive to environmental perturbation is available for sensor applications.
