In scenarios such as material composition analysis, food quality inspection, biomedical identification, chemical material monitoring, agricultural and forestry germplasm analysis, near-infrared optical calibration, etc., conventional near-infrared detection equipment generally have problems such as high dark current noise, distorted weak signal acquisition, obvious temperature drift interference, bulky size, and low detection efficiency. Ordinary non-cooled near-infrared spectrometers are highly susceptible to environmental temperature fluctuations, with severe baseline drift and poor data repeatability, which cannot meet the strict requirements of trace detection, long-term online monitoring, and high-precision non-destructive analysis. This restricts the accuracy of scientific research experiments and the efficiency of industrial batch detection.

The Sefan Optoelectronics 7IGF10-NIR-PRO near-infrared fiber optic spectrometer is a high-performance miniature spectral analysis device specifically designed for precise near-infrared detection. It is equipped with a TEC first-level cooling InGaAs dedicated sensor and an optimized fixed grating optical path. With the core advantages of active cooling for noise reduction, ultra-low baseline drift, near-infrared-specific wavelength band, portable integration, non-destructive rapid detection, and all-weather stable operation, it solves the industry shortcomings of high noise, poor stability, and bulky size of traditional near-infrared equipment. It becomes the standardized near-infrared spectrometer core equipment for scientific research laboratories, industrial production lines, and mobile field detection.

TEC first-level active cooling, extreme noise suppression and stable baseline

To address the industry common problems of high dark current noise and significant temperature drift of near-infrared sensors, the 7IGF10-NIR-PRO is equipped with a high-precision TEC first-level cooling system, which can precisely control the temperature to suppress the interference of sensor dark current, significantly reducing baseline drift and signal noise caused by environmental temperature fluctuations. Compared with conventional non-cooled near-infrared spectrometers, the overall signal-to-noise ratio is significantly improved, and the ability to capture weak spectral signals is greatly enhanced, effectively solving the problem of weak near-infrared signals being drowned by noise and data distortion. Under long-term continuous detection conditions, the baseline is straight and stable without obvious fluctuations, and the data consistency and reproducibility are fully met, fully meeting the strict precision standards of high-precision scientific research experiments, trace component analysis, and precise spectral calibration.

Near-infrared specific wavelength band, precisely adapting to all-weather detection scenarios

The device precisely covers the core near-infrared wavelength band of 900?1700nm, perfectly matching the vibration absorption characteristic intervals of organic molecules with hydrogen groups, and can accurately capture material components, moisture content, purity, component ratio, etc., of micro-spectral differences. Relying on high-precision holographic diffraction gratings and optimized spectral optical path, the spectral division is uniform, the spectral line linearity is excellent, there is no spectral distortion, and no band distortion. Whether it is complex mixed material component analysis, subtle spectral difference discrimination, or optical device near-infrared wavelength band response calibration, it can output accurate and reliable spectral data, suitable for the vast majority of near-infrared non-destructive detection and spectral scientific research scenarios.

Fixed grating compact optical path, portable integration suitable for multiple working conditions

Using a horizontal cross fixed grating optical path architecture, there are no mechanical scanning motion components, which fundamentally eliminates mechanical errors and structural losses, ensuring stable operation and a very low failure rate. The overall modular compact design is small in size and lightweight, getting rid of the drawbacks of traditional near-infrared spectrometer equipment being bulky, occupying space, and requiring complex setup and professional calibration. It can be plugged in and used quickly, providing data output. It is suitable for laboratory tabletop precise detection, can be easily embedded in industrial automation production lines, portable detection equipment, and supports mobile non-destructive sampling in the field. Its scene adaptability far exceeds traditional tabletop spectrometer analysis equipment.
