Fourier Transform and dispersive Raman microscopy

The two Raman systems that are used for the technique offer several excitation wavelengths (1064, 785, 632, 532, 498 and 458 nm). The number of possible laser excitations is rare and due to the versatile laser excitations both systems allow characterisation of many different materials, including complex organic pigments (synthetic or natural organic pigments and dyes) and logwood inks. In cases of natural organic pigments and dyes characterisation we have developed new and well performing SERS (Surface Enhanced Raman Spectroscopy) substrates.
