Extensions of FT-Raman for Longer Wavelength Operation

After consideration of the properties of dispersive/CCD Raman spectroscopy and FT-Raman, questions about alternative approaches to conventional FT-Raman often arise. First, can fluorescence be further reduced by using still longer laser wavelengths Second, wouldn t the best solution be a shot-noise-limited multichannel system operating above 1000 nm Both of these questions have been addressed experimentally, but given current technology the associated hardware developments are not yet ready for widespread use. 

So why not use a multichannel detector above 1000 nm The factor would still yield lower cross sections, but the multichannel detector would boost SNR without the distributed noise problem of FT-Raman. An array detector with negligible dark (and readout) noise that is sensitive in the 1000 to 1700 nm range would seem ideal, yielding the sensitivity of multichannel detection and the low fluorescence of 1064 nm excitation. Such detectors
