What Does FEFA Stand For?

FEFA stands for Fiber Optic Evanescent Field Absorption

FEFA, or Fiber Optic Evanescent Field Absorption, is a sophisticated optical sensing technique that involves the interaction of light with the evanescent field of a fiber optic waveguide. This method enables the detection of trace amounts of chemical and biological substances by measuring the absorption of light as it interacts with analytes present in the vicinity of the fiber's core. FEFA is particularly valuable in applications requiring high sensitivity and specificity, such as environmental monitoring, biomedical diagnostics, and industrial process control.
