Infrared (IR) spectroscopy and Raman spectroscopy are very complementary methods. The strongest demand tends to come from applications that require analytical information from a potentially broad range of compounds and functional groups. The global market for combined Raman and FT-IR accounts for a small but growing percentage of both the broader IR and Raman spectroscopy markets.

The handheld and portable Fourier-transform infrared (FT-IR) market is a very new and rapidly growing market thanks to the intersection of technological advancements and new demand. Relative to other portable analytical technologies, the range of applications for the technology is more diverse. Despite the rapid growth and potential for this market, however, only a handful of competitors currently dominate the market.
