SuperGamut Spectrometer Series

The SuperGamut spectrometers are part of the silicon CCD spectrometer series covering the VIS-NIR (400 nm to 1,100 nm) wavelength range, and the UV-NIR (190 nm to 1,080 nm) wavelength range. These spectrometers utilize a highly efficient Volume Phase Grating (VPG®) as the spectral dispersion element, and employ an ultra-sensitive CCD array detector as the detection element. With these elements, the spectral engines are able to provide high-speed parallel processing and continuous spectral measurements.
