DETAIL

MS11639 is an industrial miniature optical fiber spectrometer with a spectral range of 200nm~1100nm (configurable). It features high resolution, low stary light and low temperature drift. Further, the detector is using highly sensitive linear array CMOS sensor that can efficiency provide the spectrometer with high signal to noise ratio and wide dynamic range.
 

About the applications, MS11639 can be used in laser measurement, plasma emission spectrum measurement, color measurement, absorbance measurement, Raman measurement and other industrial field measurement.
