Shifted Excitation Raman Difference Spectroscopy (SERDS)

We offer a unique SERDS pair module option LabSource that is comprised of two laser sources with closely spaced wavelengths, ranging from 0.1 nm to about 1 nm apart. These modules are intended for SERDS, a method which greatly reduces the fluorescence interference in Raman Spectroscopy measurements. Please see the application note for more detailed information regarding SERDS.
