Fiber Bragg Sensor Gratings

Product Description: 

A fiber Bragg grating (FBG) is a type of distributed Bragg reflector formed in a short segment of optical fiber. It reflects particular wavelengths of light and transmits all others. The Bragg wavelength will change when the fiber grating experience any change in fiber properties, such as strain or temperature which varies the reflective index or grating pitch. we offer both acrylate and polyimide coated fiber Bragg gratings.
