产品介绍
Gold Coated FBG
Gold Coated FBG not only offer the mechanical protection and hermetic seal needed in harsh environments, the enhanced sensitivity through plasmonic effects is also particularly useful for bio-chemical measurements. Gold coated fibers rated from -269°C to 750°C, though for most applications the gold coated fibers will continue to protect the fiber to 1,000°C. The high-temperature performance of gold-coated FBG, combined with excellent corrosion resistance and the ability to be soldered or brazed, makes these sensors ideal for many demanding sensing applications.
