SR50C (SR75C) miniature spectrometer

Short Description:

The SR50/75C series miniature spectrometer is a small-volume, high-performance, cost-effective multi-purpose spectrometer, covering ultraviolet, visible, and near-infrared bands, and can be used for Raman scattering spectroscopy, as well as detection analysis of reflection, transmission, and absorption spectra.
SR50/75C series spectrometers use 2048-pixel high-sensitivity COMS, support the wavelength range of 200-1100nm, and are equipped with low-noise, high-speed processing circuits, excellent signal-to-noise ratio and extremely fast response speed.
The SR50/75C series is compatible with SMA905 optical fibre and free space input, and data transmission supports USB2.0 and UART, which is convenient for scientific research users and industrial users to integrate.
