The ONIR High-Speed Near-Infrared Spectrometer is designed for high-precision spectroscopic measurement applications. Covering a spectral range of approximately 1290–1330 nm, it is optimized for the 1310 nm near-infrared region and combines high optical resolution, high-speed spectral acquisition, and real-time network communication to capture transient spectral changes with high accuracy.
Featuring a 10 μm precision slit and a high-performance optical design, ONIR delivers an optical resolution of approximately 0.4 nm, enabling clear differentiation of fine spectral features. With spectral acquisition speeds of up to 3000 fps, it is capable of real-time monitoring of laser wavelength drift, fiber optic component characteristics, and spectral changes in high-speed processes.
The system is equipped with Gigabit RJ45 Ethernet and a 24-pin expansion interface, supporting high-speed data transmission, remote control, and secondary development. These features enable seamless integration into various spectroscopy platforms and measurement systems for research, equipment integration, and in-line measurement applications.
ONIR is ideal for fiber optic communication component testing, laser wavelength monitoring, thin-film thickness measurement, near-infrared spectroscopy, and scientific research, providing a fast, stable, and accurate solution for near-infrared spectral analysis.
