Uniform FBG
We offer the uniform gratings with grating length 0.5mm to 10mm. Such gratings have FWHM from 0.015nm (R=25%) to 0.03nm (R=90%) for wavelength 633nm (0.1nm and 0.17nm at wavelength 1580nm) and gratings length 9mm. Standard Uniform FBGs have bandwidth 0.15nm – 0.6nm, reflectivity 5% - 99% and gratings length 1mm – 3.5mm. Fiber Bragg gratings are sensitive to strain and temperature changes. Uniform FBGs can be provided as separated or chain of FBGs with different wavelength. Multy - points temperature, strain or other physical parameter monitoring are available by use of chain FBGs. Different types of single mode optical fibers and fibers coating are used for writable. Acrylate coating fibers applying for normal temperature range 40˚C to +100˚C. Polyimide or metal (Cu, Al) coating fibers are used for high temperature application with maximum temperature 300˚C and 500˚C respectively. The experimental and theoretical reflection spectrum of FBGs is presented in the graph.
