SR50C/SR70C Drive Circuit

Short Description:

The drive circuit of JINSP, compatible with JINSP SR50C/SR75C universal optical fiber spectrometer, utilizes a professional high-speed, low-noise signal acquisition and processing circuit for the optimal spectral signal-to-noise ratio. Incorporating an internal temperature sensor for real-time monitoring of ambient temperature, in conjunction with an internal temperature drift compensation algorithm, it ensures minimal temperature drift within the operating temperature range. Ideal for integration into various common spectroscopic measurement systems, it enables high-resolution spectral detection across ultraviolet, visible, and near-infrared wavelengths.
