28mm 24mm FBG Fiber Bragg Grating Coated with Gold and Nickel
FBG Fiber Bragg Grating Coated with Gold and Nickel with electroless plating process for FBG sensor
Description
With the mature chemical plating process, Nickel and Gold is plated successively on the optical fiber core, or the coating layer of the optical fiber. And the plating position can be customized according to customer requirements.
Gold recoating FBG adopts electroless plating process that recoats a Nickel layer on single side or middle point of the optical fiber core (Or optical fiber with coating) with relative length; next coat a Gold layer then.
Application:
Optical parts connection Package Strain Gauge.
Feature:
Directly welding with metal base that increase the packaged FBG sensor precision and service lifetime.
