High-Strength Fiber Bragg Grating (FBG) - UV-Transparent Coating, No Stripping, High-Tensile, Large-Strain FBG
DCYS is a professional high-strength FBG manufacturer, providing high-strength FBG parameters, customization, wavelength, usage and other information; the high-strength FBG brand is "OFSCN". Bulk purchase, better price!
This product is manufactured by OFSCN. It is a high-strength fiber bragg grating (FBG) produced using UV photolithography, featuring a UV-transparent coating made of polyacrylate. 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.
DCYS's high-strength FBG is directly written on the fiber without the need for stripping the coating during the fabrication process. This unique method combines the advantages of non-destructive writing, high strength, and high tensile properties found in draw tower FBGs, along with the flexibility, multi-wavelength capability, and high reflectivity of UV photolithography-written FBGs. 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.
