In demanding scenarios such as advanced spectral research, weak fluorescence detection, precise light source characterization, trace material analysis, high-order calibration of optical devices, and high-precision industrial quality control, ordinary general-purpose spectrometers often have core shortcomings such as high stray light, insufficient signal-to-noise ratio, poor weak signal capture capability, obvious baseline drift, and the absence of fine spectral line resolution. Conventional equipment is difficult to distinguish minute spectral differences and cannot accurately collect weak characteristic signals, resulting in distorted high-end experimental data, poor repeatability, and inability to meet journal-level scientific research and precise detection traceability standards, becoming the core bottleneck of high-precision spectral research and high-end quality inspection.

The Sefan Optoelectronics 7IGF10-PRO high-performance fiber optic spectrometer is the flagship model of the 7IGF series for scientific research-level high-order applications. It has comprehensively upgraded the optical architecture, core chips, and stray light suppression system based on the standard version, equipped with imported high-end back-illuminated CCD sensor chips, large-sized holographic gratings, and optimized stray light elimination optical paths. With ultra-low stray light, ultra-high signal-to-noise ratio, extreme weak light capture, nanometer-level precise resolution, all-weather ultra-stable output, and all-scenario high-order adaptation, it breaks through the accuracy limit of micro-spectrometers and becomes a benchmark core equipment for university front-line research, high-end material research, and precise optical detection.

Professional stray light elimination optical path architecture, industry-leading ultra-low stray light, and ultra-pure baseline

The 7IGF10-PRO is equipped with an upgraded horizontal cross-stray light elimination optical path system, combined with exclusive shading structures and optical path noise reduction processes. The stray light suppression capability is as low as 1×10⁻³, far superior to that of ordinary general-purpose spectrometers. It uses a 22mm×22mm large-sized high-precision holographic diffraction grating, with uniform dispersion and superior spectral resolution, filtering out high-order diffraction light, environmental scattering light, and residual noise from the optical source. The entire spectral baseline is flat without elevation or interference from peaks, the spectral line contour is sharp without distortion or broadening blurring, and it can accurately distinguish subtle spectral deviations and overlapping characteristic peaks, perfectly supporting high-order fine spectral analysis, weak signal purification, and ultra-low concentration sample detection in high-precision scenarios.

High-end back-illuminated CCD chip, ultra-high signal-to-noise ratio, and powerful weak signal capture

The equipment core is equipped with an imported back-illuminated 2048-pixel CCD sensor chip, which upgrades the photoelectric conversion efficiency, sensitivity, and dynamic range compared to ordinary area array sensors, with a significant increase in signal-to-noise ratio. For weak fluorescence signals, low-transparency films, trace solute detection, and weak light source spectral calibration under low-energy conditions, it can efficiently capture effective signals, strongly suppress baseline noise, and completely solve the industry pain point of weak signals being drowned by noise and data distortion. Multiple consecutive scans have no drift or deviation, and the data consistency, reproducibility, and traceability fully meet the strict data standards of high-level scientific research papers and precise measurement and detection. With its extreme spectral resolution of up to 0.03nm, the wavelength accuracy and repeatability are industry-leading, capable of precisely splitting dense overlapping spectral lines and capturing nanometer-level microscopic spectral changes. Whether it is precise LED light source spectral color matching, narrowband optical device band calibration, material fine absorption/fluorescence spectral analysis, or trace chemical component difference identification, it can accurately restore the spectral true characteristics, capture microscopic data differences that ordinary spectrometers cannot identify, and provide reliable data support for high-precision experiments and high-end quality inspection.

No mechanical fixed optical path design, long-term ultra-stable maintenance-free operation

Continuing the mature and reliable fixed grating integrated optical path structure of the series, the entire machine has no any mechanical scanning motion components, eliminating mechanical wear, zero-offset error, jamming offset, and lifespan degradation faults from the root. The fuselage's rigid structure has been strengthened and upgraded, enhancing its resistance to vibration, shaking, and temperature variations. It can be adapted to various demanding scenarios such as laboratory high-frequency debugging, industrial complex conditions, and long-term online monitoring. It supports 7×24-hour uninterrupted continuous operation and requires no frequent calibration or complex maintenance. The failure rate is extremely low, and its long-term stability far exceeds traditional scanning spectrometers, significantly reducing the costs of research and industrial operation.
