Luminescence based fiber optic probe for the detection of rare earth elements
Abstract
The disclosure relates to an apparatus, method and process for detecting rare earth elements. The system includes an LED powered by a first power source and a focusing lens in optical communication with the LED. A shortpass filter is in optical communication with the focusing lens; and a fiber bifurcated cable in optical communication with the shortpass filter. The system includes a probe tip in optical communication with the fiber bifurcated cable and a sample; a first aspheric lens in optical communication with the fiber bifurcated cable. A longpass filter is in optical communication with the first aspheric lens and a second aspheric lens in optical communication with the longpass filter. The system includes a spectrometer connected to a power source, where the spectrometer is in optical communication with the second aspheric lens.
