The drive circuit of JINSP, compatible with JINSP SR100B optical fiber spectrometer. The detector board is designed to accommodate back-illuminated CCD arrays, offering a larger light-sensitive area and improved spectral stability. The quantum efficiency within the 200-1100nm range approaches 80%, with quantum efficiency as high as 60% in the ultraviolet range. The driver circuit, combined with advanced FPGA low-noise, high-speed signal processing circuitry, delivers outstanding spectral signals with stable and reliable performance.
