How Concatenation Enhances Raman Spectroscopy

October 14, 2020

This application note explains the concept of Raman Concatenation, which allows users to visualize the Raman spectra from 0 to 4000 cm by utilizing two lasers.

How Does Concatenation Enhance Raman Spectroscopy?

September 01, 2020

In general, many Raman measurements suffer from fluorescence, which forces the use of longer excitation wavelength (lower photon energy) lasers to prevent the fluorescence signal from overwhelming the Raman signal. However, this results in reduced sensitivity of low-cost silicon CCD detectors at higher wavenumbers, making it difficult (or impossible) to observe the “stretch” portion of the Raman spectra.
