It covers not only the telecommunication wavelengths but also the exNIR region which is nowadays often and often used for environmental sensing and medical applications of photonic technology. It is equipped with a closed-loop circuit for air purging which is very effective in cleaning up the detected spectrum from the water vapor absorptions which may affect the accuracy of the measurement.
