Abstract
A fiber-optic spectroscopic probe for use with an FTIR spectrometer comprises two or more types of optical fibers made from materials with overlapping transmissions in the infrared region of the spectrum. The fiber materials are chosen so that so that any regions of low or zero transmission in their respective transmission windows, arising from impurities or defects in the material, occur in different spectral regions, thus ensuring that the probe is able to transmit across the entire transmission window without exhibiting the characteristic "blind spots" that are observed using probes comprising a single type of optical fiber.
