SR100Q Drive Circuit

Short Description:

The drive circuit of JINSP technology Compatible with JINSP SR100B optical fiber spectrometer, the board is compatible with scientific-grade cooled area array CCD chips, featuring a surface area four times larger than ordinary pixels, and boasts a quantum efficiency as high as 92%. There is a still high response in the ultraviolet band, effectively enhancing the sensitivity and signal-to-noise ratio for faint signals. Adopting advanced high-resolution optical path design along with FPGA low-noise, high-integrity signal processing circuitry, it delivers exceptional spectral signals with stable and reliable performance, making it an ideal choice for low-light detection. It is suitable for applications involving fluorescence, absorption, Raman spectroscopy, and more, across the ultraviolet, visible, and near-infrared wavelength bands.
