The detector of the spectrometer adopts the CMOS linear image sensor - Hamamatsu S11639 which can provide the spectrometer with high signal-to-noise ratio and large dynamic range.
The spectrometer is able to provide a better transmission speed and a stable wavelength thanks to its durable integrated circuit and compact design. It can also achieve stable Raman spectrum measurement from 0℃ to 40℃.
With compact size and superior capability, XS11639 series is commonly applied to optical spectroscopy research, such as absorbance, reflectance, Fluorescence spectrum and Raman spectrum. It can also be used for industrial equipment, such as smoke monitoring, water quality inspection, elemental analysis.
