Market Profile: Raman Spectroscopy

Raman is a lesser known light scattering phenomenon by which an excited electron returns to a different rovibronic state than before in molecules, and the extra energy changes the vibrational mode of the particle. This causes a photon to be emitted at a different frequency than before. Raman spectroscopy uses this phenomenon to identify different substances according to their molecular structure. In Raman spectrometers, after scattering occurs through a sample using lasers, the resulting photons are sent through a monochromator and guided to a charge-coupled device for signal analysis using band filters and sometimes a Fourier transform analysis.

Raman technology is a relatively old form of spectroscopy that became more prevalent after the development of lasers. Raman scattering was discovered by C. V Raman in 1928, and Raman used a mercury lamp and photographic plates to record spectra. However, this archaic process took hours or days to acquire spectra due to weak light sources.

Raman spectroscopy can be applied to many fields where nondestructive chemical analysis and microscopic imaging needs to be provided rapidly. It can analyze many states of matter such as solid, liquid, gases, and even gels and slurries. It is used in a variety of applications such as pharmaceutical, cosmetic, material, semiconductor, and life science industries and research. The most common types of Raman spectrometers are microscopes, portable, dispersive, and Fourier transform, with portable Raman spectrometers being the highest selling instruments. Vendors such as Acutech, B&W Tek, and  Spectra Solutions provide portable Raman spectrometers. Cloudminds Technology has a palm sized Raman spectrometer that uses cellular, WiFi, or Bluetooth to communicate with their AI cloud.

The total market for Raman spectroscopy instruments was measured at over $300 million in 2018 with around 4500 units shipped annually. Portable spectrometers account for the largest share of the market with nearly half of the market. In the past decade, the market has significantly shifted to portable devices rapid and flexible analysis.
