SPELECRAMAN638 is an instrument for performing spectroelectrochemical Raman measurements. It combines in only one box a laser class 3B (638 nm ± 0.5), a bipotentiostat/galvanostat and a spectrometer (wavelength range 640 – 885 nm and Raman shift 50 – 4370 cm-1) and includes a dedicated spectroelectrochemical software that allows optical and electrochemical experiments synchronization.
