DETAIL

XS11639 is a basic optical fiber spectrometer with a cross CT structure design. It has a compact size and the spectral range can be configured between 190-1100nm. With special lens fixing process and photoelectric separation structure, it has good temperature stability and reliability. Furthermore, we chose the UV-enhanced CMOS detector which can optimize the UV response.

XS11639 is the valuable spectrometer which can be used in color measurement, radiation measurement, absorption measurement, fluorescence spectrum, Raman spectrum and other measurement scenarios.

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.
