This product adopts an athermal packaging structure to minimize the sensitivity of the Fiber Bragg Grating center wavelength to environmental temperature changes. The athermal package can reduce the temperature sensitivity of the FBG center wavelength by more than 20 times and maintain the stability of the FBG center wavelength within the temperature range of 0 ~ 70℃, with a temperature drift of the center wavelength as low as 0.5 pm/℃. The athermal package features a rugged hard stainless steel structure, with the FBG fiber equipped with a 900 μm protective loose tube along its entire length, and strain-relief rubber boots installed at both ends. The package adopts a cylindrical structure, allowing for quick and easy installation and fixing.
