SINGLE FBG
Besides customer specific FBG solutions, engionic Femto Gratings offers an attractive range of standardized fs-written Fiber Bragg Gratings. Due to the worldwide leading, automated manufacturing technology, we can provide high customer value in terms of quality and cost efficiency.
Our Femto Gratings are of superior tensile strength, withstand temperatures of up to 1,000°C and can be immune to radioactivity and humidity. The product line of FemtoPlus® Gratings additionally provides extremely low polarization (0-5pm) for high resolution measurements and very low scattering loss (<0,2dB) for extra-long array configurations.
