NIR spectroscopy provides rapid, damage-free fruit inspection by evaluating spectral patterns in the near-infrared band. It quantifies key parameters like sugar levels, acidity, and hydration, facilitating objective quality assessment and industrial applications.

The JINSP SR100N series offers dual-wavelength models (1.7μm & 2.5μm) for flexible NIR spectroscopy. With embedded optical filters, they exclude unwanted light, while the cooled InGaAs detector (512px) minimizes noise. Suitable for transmissive, reflective, and absorptive measurements.

NIR spectroscopy (780-2500nm) captures molecular vibration responses to light absorption. Agricultural samples exhibit wide absorption bands from overtone vibrations of common bonds (O-H, C-H), allowing simultaneous chemical characterization and multi-component analysis for quality control applications.

• Near-infrared reflection detection method: Suitable for detecting information on the surface of fruit peels, such as color and luster, but not for internal quality detection.
• Near-infrared transmission detection method: Theoretically applicable to transparent or semi-transparent samples and cannot penetrate fruits. Less used in practical applications.
• Near-infrared diffuse reflection detection method: A measurement method between reflection and transmission, suitable for opaque, solid and semi-solid samples. The obtained spectral information can reflect the characteristics of the internal structure of fruits and is widely used in the detection of internal qualities of fruits (such as sugar content, acidity, etc.).

• Quality assessment: Predict quality parameters such as firmness, sweetness, and acidity of fruits.
• Classification and identification: Distinguish and identify the types of different fruits.
• Functional fruit evaluation and screening: Can be used to evaluate and screen functional fruits rich in special components.
• Disease monitoring: Can quickly diagnose diseases such as citrus Huanglongbing and provide early warnings for disease prevention and control.
