UV-enhanced Spectromters

Fiber Optics Spectrometer 200-400nm - XS11639 Series

XS11639-200-400 is a fiber optic spectrometer with a spectrum range of 200-400nm.
DETAIL

The detector of the spectrometer adopts the CMOS linear image sensor - Hamamatsu S11639 that features include high sensitivity and high resistance in the UV region. Thanks to its durable integrated circuit and compact design, the spectrometer can provide a better transmission speed and a stable wavelength. The spectrometer 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. It can also be used for industrial equipment, such as smoke monitoring, water quality inspection, elemental analysis.
