SR100Z Drive Circuit

Short Description:

The drive circuit of JINSP, compatible with JINSP SR100Z optical fiber spectrometer. The detector board is compatible with cooled back-illuminated area CCD chips. With its large photosensitive area and cooling features, it can receive more optical signals, enhancing the signal-to-noise ratio of the spectrum. Within the 200~1100nm range , the detector board exhibits a quantum efficiency twice that of linear array sensors, and it also achieves up to 70% quantum efficiency in the ultraviolet wavelength band. The drive circuitry adopts advanced FPGA low-noise, high-speed signal processing circuits, resulting in excellent spectral signal acquisition with stable and reliable performance.
