LOCATION:HOME Theory of Fluorescence

 

Optsensor's Fluorescence Fiber Optical Monitoring System is based on the characteristics found in rare earth fluorescent materials. Upon being stimulated by a light source, electrons inside the sensitive, rare earth material absorb photons, triggering a reaction and causing electrons to move from a low to a high state of excitation. Once the light source has dissipated, the strength and duration of the fluorescent life span becomes dependent upon the life span of the light source and is highly reproducible over a wide temperature range. The range is called the fluorescence lifespan. One of the many advantages resulting from this method of temperature monitoring is that the monitoring target only relies on the elapsed time of the excited fluorescent material. The accuracy of the measurement is not affected by the light source's intensity, transmission loss, or optical coupling efficiency. With high interchangeability, stability, a long life expectancy, and no need to calibrate measurements, Optsensor's Fluorescence-Based Fiber Optical Monitoring System clearly has advantages over other sensing methods.
