Raman
Raman spectroscopy takes a molecular fingerprint and matches it against a library to identify and confirm samples. Raman fingerprints have very fine structural detail that make identification accurate and reliable. Raman can also provide information about the amount of material present in a sample or a mixture.
Assembling a Raman System
Raman systems consist of
- A laser to excite Raman emission
- A fiber optic Raman Probe to collect the Raman emission from the sample
- A spectrometer to collect the Raman spectrum.
The choice of fiber optic probe for sampling is critical, given that it has to allow the laser light to reach the sample but then exclude it from the detectors. High-performance B&W Tek components move light efficiently, providing high sensitivity.

Choosing The Most Suitable Laser Wavelength
When choosing a Raman instrument, one of the primary concerns is the wavelength of the laser integrated into the Raman spectrometer system. Different excitation wavelengths provide specific strengths and weaknesses, allowing users to optimize the measurement of different samples by choosing the Raman excitation laser wavelength.
The Advantages of a Compact, Thermoelectrically-Cooled Fiber Optic Spectrometers
The benefits of a TE-cooled spectrometer in Raman systems are discussed, such as delivering lower system noise over longer integration times, resulting in lower detection limits.
