ST90S Transmission Fiber Spectrometer: Superior Signal-to-Noise for Critical Detection Tasks
High Sensitivity Spectrometer for 532nm Raman Imaging Systems
Achieve a new level of precision in your spectral analysis with the JINSP ST90S, a high-throughput transmission fiber spectrometer meticulously designed for applications where signal-to-noise ratio and sensitivity are paramount. Optimized for 532 nm excitation systems, the ST90S delivers outstanding optical performance, making it the perfect instrument for gas Raman spectroscopy, advanced material analysis, and cutting-edge research.
The ST90S's core advantage stems from its use of a VPH volume holographic transmission grating, which achieves a remarkable diffraction efficiency of 90%. This key component is the foundation of a high-throughput optical path (Numerical Aperture 0.25) that maximizes light collection. Consequently, the system offers sensitivity that is five times greater than that of standard reflective spectrometers. This enhanced light gathering power is critical for detecting weak Raman scatterers, such as gases, enabling the capture of clear, detailed spectra even with brief acquisition times, as demonstrated by its capability to acquire a 1-second air Raman spectrum with a 5W laser.
Complementing the optical front end is a research-grade Andor iVac 316 deep-cooling area array CCD. This detector is specifically chosen for its high quantum efficiency and exceptionally low dark current, ensuring an outstanding signal-to-noise ratio. This allows the ST90S to resolve fine spectral details with a resolution down to 4 cm⁻¹, covering a broad spectral range from 260 to 4200 cm⁻¹. The instrument provides clean, high-fidelity data essential for accurate qualitative and quantitative analysis in demanding fields like online gas detection, chemical process monitoring, and biomedical research.
Built for reliability, the ST90S features a zero-aberration design that guarantees diffraction-limited imaging performance. Its robust construction ensures high stability for both laboratory and industrial environments. With flexible input options including SMA905 and Φ10mm multi-core fiber interfaces, it readily adapts to various integration needs. For scientists and engineers who require a spectrometer that combines high throughput, exceptional signal purity, and robust performance, the ST90S stands as a superior and reliable solution.
