ABSTRACT:
A fiber-optic probe, useful for light scattering and luminescence measurements, which comprises at least one optical fiber for transmitting light into a sample and at least two optical fibers for collecting light from the sample. The probe may further comprise a shield surrounding the fibers and having an optical window at one end to protect the fibers from hostile environments. When used in conjunction with a laser as a light source, the probe is particularly suited for Raman spectroscopy.
