Choosing the Most Suitable Laser Wavelength for Your Raman Application

Dispersive Raman spectroscopy has increasingly been implemented for material identification due to its portability and sampling flexibility. However, when choosing a Raman instrument, one of the primary concerns is the wavelength of the laser that is integrated into the Raman spectrometer system. This application note discusses how to select a laser excitation wavelength for specific applications, considering the most widely used wavelengths which are 532nm, 785nm and 1064nm.
