Capillary Fiber Bragg Grating - Thin-diameter Fiber Bragg Grating Array - 50μm Coating Diameter FBG - 80μm
DCYS is a professional manufacturer of thin-diameter fiber Bragg gratings, providing information on thin-diameter FBG parameters, customization, wavelength, applications, etc.; our brand of thin-diameter FBG is "OFSCN". Bulk purchase, better price!
This product is a customizable fiber bragg grating (FBG) or fiber bragg grating array fabricated on capillary fibers with a coating diameter of either 50μm or 80μm. The fibers can be coated with polyimide or polyacrylate or left uncoated. They are designed to be used with "OFSCN® Capillary Series Fiber Bragg Grating Temperature Sensors (FBG Thermometers), Fiber Bragg Grating Strain Sensors (FBG Strain Gauges), and Fiber Bragg Grating Stress Sensors (FBG Load Cells)". The parameters listed for the capillary fiber bragg grating (FBG) are for reference only. The parameters may vary slightly when the FBG sensors are fabricated, and customization is available to meet specific user requirements.
