A brief introduction: XS13256 adopts a back illuminated linear array CCD sensor, which adopts a resistive grid structure and can achieve high-speed transmission. In addition, the built-in TE cooler can maintain a constant component temperature (minimum 2 ° C) during operation, allowing the spectrometer's dark noise to be controlled within~± 10counts@100ms The XS13256 adopts a C-T optical path design internally, and through optimized optical path design and strict selection of optical components, it can achieve higher spectral resolution and eliminate stray light interference inside the spectrometer.
