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.

Specifications :

	Central Wavelength Range	780~1650nm
	CWL Tolerance	±0.2nm
	Reflectivity	>90% or customized SPEC
	3dB Bandwidth	around 0.22nm
	Side-Mode Suppression Ratio	> 15dB
	Coating Material	acrylate and polyimide for high temperature
	Packaging	None
