JINSP SR50R17 near-infrared spectrometer is a compact and cost- effective instrument operating from 900 nm to 1700 nm. It features a non- cooled InGaAs sensor, providing high sensitivity and resolution.
JINSP SR100N25 near-infrared spectrometer with cooling technology supports wavelength ranges of 0.91.7μm or 0.92.5μm. With a wide range of applications, it integrates filters to eliminate visible light and higher-order filters. This spectrometer is suitable for near-infrared spectroscopy detection in transmission, reflection, and absorption spectra.
JINSP SR50N14 refrigerated near-infrared miniature spectrometer is a lightweight, highly stable, and high-resolution miniature spectrometer. It features a 512-pixel refrigerated InGaAs sensor, supporting the wavelength range of 0.9μm to 1.5μm, in 1064 nm Raman spectroscopy with excellent performance.
• Small size and lightweight.
• Gold-coated lens surface for high near-infrared reflectance efficiency.
• Compatible with USB or UART to output measured spectral data, easy to integrate.
• Compitable with SMA905 optical fiber input to obtain free space light.
• Adopts on-chip cooling technology and configures low-noise signal processing circuit, effectively suppress dark current noise and improve spectral signal-to-noise ratio (SR100N&SR50N).
