SEC2000 Spectrometer, a multi-channel spectrometer, is specifically designed for spectroelectrochemical measurements. The combination of the spectrometer and light source, allows having UV/VIS and VIS/NIR mode. In the light source, the lens is incorporated to the light in a small module, it eliminates the need of fiber optics. Detector and light source could be set to the cell holder in a 90 degrees angle for measurements of the fluorescence
