XS11071 is a long-focal length, back-illuminated, high-sensitivity fiber optic spectrometer based on symmetrical CT optical path design. It is compact and can be configured within the spectrum range of 200-1100nm. It features high resolution (the best up to 0.1nm) and low stray light (~5‰). Meanwhile, it equipped with high sensitivity back-thinned CCD which has good signal-to-noise ratio and wide dynamic range. It is definitely a valuable fiber optic spectrometer which suitable for laser measurement, plasma emission spectrum measurement, color measurement, absorbance measurement, Raman measurement and other industrial field measurement.

1. CCD readout noise: integration time 10ms, CCD readout noise root mean square; 2. CCD dynamic range: the dynamic range is the saturation value of 2ms integration time/the root mean square of CCD readout noise, the evaluation method refers to the standard of enterprise; 3. Response linearity: The response nonlinearity is before calibration.
