Fiber Optics Spectrometer 790-1050nm - XS11639 Series

DETAIL

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. Thanks to the durable integrated circuit and compact design, XS11639 series would be able to provide a better transmission speed and a stable wavelength. It can also achieve stable Raman spectrum measurement from 0℃ to 40℃.

With compact size and superior capability, XS11639 series can be applied to optical spectroscopy research, such as absorbance, reflectance, Fluorescence spectrum and Raman spectrum.
