High etendue low light Raman Spectrometer for identification of liquids Many industries suffer from liquid contaminant species affecting the efficiency of their processes. In many applications it is not possible to recover a sample of these liquids additionally they may pose risk if they are exposed to the public. There is a clear need for tool that can remotely analyse these liquids and identify there chemical makeup. Using a new type of Spatial Domain Fourier Transform spectrometer ISI has developed a new instrument with an etendue of a FTIR while proving the spectral coverage of a Czerny Turner device. This allows the resulting spectrometer to be used in extreme low light conditions allowing trace species to be identified. This opens the possibility of the Raman spectra to be recovered from a variety of challenging environments including buried pipes lines. This device is currently in development with design being produced for operation on Gas pipelines. Key features Suitable for Raman spectroscopy Identify samples up to 3 m from the instrument High optical throughput Near photon counting operation Robust design Currently in testing programme
