A single optical probe does double duty

Investigators engaged in fluorescence spectroscopy have had two less-than-perfect choices for fiber optic probes — single- and multifiber. A single-fiber probe has the advantages of a small diameter, a simple configuration and low cost. However, a multifiber probe does not autofluoresce from excitation light as single-fiber types do. This autofluorescence, or background, signal can make it difficult to detect weakly fluorescent samples with a single-fiber probe. Now a team of researchers from South Korea has demonstrated fluorescence spectroscopy using a single double-clad fiber that...Read full article
