This product is manufactured by OFSCN. The fiber Bragg grating is written on high-strength optical fiber using femtosecond laser writing method, direct writing through the coating without stripping, polyacrylate/polyimide coated, high-strength fiber Bragg grating (FBG).
Based on its high strength and high tensile properties, it can be matched with OFSCN® capillary seamless steel tube series FBG strain sensors (FBG strain gauge), FBG stress sensors (FBG tension gauge).
The parameters provided for the FBG are for reference only, as the characteristics may vary slightly after the FBG is integrated into a FBG sensor. Customization options are available to meet different user requirements.

Features of High-Strength Fiber Bragg Grating:
Traditional FBGs are typically produced using UV photolithography, which requires the removal of the fiber coating to overcome UV light blocking and absorption. This process, followed by re-coating after FBG writing, compromises the strength and tensile properties of the final FBG product.
The high-strength fiber Bragg grating produced by DCYS is made of selected OFSCN® high-strength optical fiber and is directly written by femtosecond laser. There is no need to strip the coating layer during the production process of the fiber Bragg grating. The OFSCN® high-strength fiber Bragg grating has the advantages of no damage, high strength, high tensile strength, and flexible wavelength customization.
It can be used in OFSCN® capillary seamless steel tube series FBG strain sensors (FBG strain gauge), FBG stress sensors (FBG tension gauge), and can also be used as standalone FBG sensors without encapsulation.
