SPELECRAMAN is a tool for spectroelectrochemical Raman measurements. It combines a laser class 3B (785 nm ± 0.5), a bipotentiostat/galvanostat, and a spectrometer (wavelength range 787 – 1027 nm and Raman shift 35 – 3000 cm-1) into one box.
It also comes with specialized spectroelectrochemical software that synchronizes optical and electrochemical studies.
