We are looking for a Raman spectroscopy system, which will be used for in situ studies of batteries, heterogeneous catalysts and ceramic electrochemical cells. For this reason the system must be flexible with respect to mounting of different ready-made and home-made in situ testhouses. Two “measurement stations” are wished in the set-up, a ‘classic’ Raman microscopy station and a station using a microscope objective connected with a glass fiber cable to the spectrometer.
