Fiber Bragg Grating Sensor FBG Array Wavelength 1460nm 1610nm
FBG Sensor is one of the uppermost inventions in the 90’s, 20th century. FBG is a passive optical devices, with good reliability, high measurement precision, resistance to electromagnetic interference and anti-lightning characteristics. Adopting 11460nm -1610nm (usually1,525~1565nm) wave band grating and grating apodization combination technique.
SAMYON can supply different kinds of FBG : High Refletivity 99% Bared Fiber Bragg Grating, Multi fiber bragg grating arrays on single optical fiber , Phase Shift Fiber Grating, Long Period Fiber Grating, Chirped Fiber Grating, Blazed Fiber Bragg Grating, Althermal Packaged FBG, Low refletivity FBG 0.1% and Femto FBG which can bear Max1000 Celsius Degree.
Based on different industrial application, Bared FBG or FBG arrays are been packaged into variable sensors: Temperature sensor with ceramic, Stainless steel tube, 2mm diameter Stailess Steel Capillary, small diameter Quartz tube; Strain gauge with surface mounted plate type, Re-useage stainless steel tube type , sticked in steel bar type, diamond type,etc; Displacement Sensor; Pressure sensor for water , soil and gas; Level Meter, and so on. The Bared FBG also without packaged also can be used for above application to increase its sensitivity.
