CHN SPEC FS-IQ-VISNIR Portable Hyperspectral Camera (1920 * 1920, 400~1000nm)

CHN SPEC FS-IQ-VISNIR Portable Hyperspectral Camera (1920 * 1920, 400~1000nm)

The CHN SPEC FS-IQ-VISNIR Portable Hyperspectral Camera (Portable Smart VNIR Hyperspectral Camera) is an “All-in-One” device specially designed for professionals who frequently conduct outdoor surveys or work in the field. By combining the visible and near-infrared wavebands (400 – 1000 nm) with an ultra-high resolution image sensor of 1920 × 1920 pixels in a mobile design, this device allows for the extraction of biochemical structures and the evaluation of material appearance right on the spot without needing to take samples back to the Lab.

Outstanding Features

• Portable & Smart design: Belonging to the IQ product line, the camera is integrated with an internal processing computer system, a high-capacity battery, and an intuitive touch screen. This design frees the device from bulky computer systems or complex cables, allowing users to carry it by hand and scan samples anywhere.
• Ultra-sharp resolution (1920 × 1920 pixels): Possessing one of the highest spatial resolutions among portable hyperspectral series, the FS-IQ-VISNIR captures all surface details at the micro-level. Every pixel in the 1920×1920 image carries a continuous spectral graph, helping to detect extremely small defects such as leaf veins, microscopic impurity particles, or fabric yarn structures.
• VNIR spectral band (400 – 1000 nm): This wavelength band covers all visible light to analyze colors, while extending into the Near-Infrared band to “see through” biochemical characteristics. This combination is extremely sensitive in measuring chlorophyll levels, plant surface moisture, and evaluating the freshness of organic foods.
• 3D Data Cube acquisition (Hypercube): When scanning an object, the machine generates a multidimensional data block (X, Y, λ). You can touch any point on the image on the screen to instantly view the spectral graph at that location.
• AI Processing & Real-time results (Edge Computing): The internal processing power allows the camera to run AI and Machine Learning algorithms right on the device. It can analyze data, color-code defective goods alerts (e.g., highlighting bruised areas on fruit), and display biochemical maps directly on the screen in real-time.

Practical Applications

Mobility combined with ultra-high definition makes the CHN SPEC FS-IQ-VISNIR an invaluable tool in fields requiring field surveys:

Precision Agriculture & Field Phenotyping: Agricultural engineers can bring the machine directly to the fields to scan leaves, instantly calculating plant health indices (NDVI, chlorophyll levels), and early detecting pests, diseases, and water shortage without needing to pluck leaves and take them back to the Lab.

On-site Food & Agricultural Product Inspection:

• Evaluating the freshness of meat and seafood directly at wholesale markets or fishing ports.
• Scanning fruits on the tree or in warehouses to detect hidden bruises or evaluate biochemical ripeness before harvesting.

Forensics & Criminal Science: Investigation experts can bring the device to crime scenes to scan for microscopic bloodstains that have been wiped away, or distinguish printing inks in forged document authentication right at the desk.

Museums & Art Restoration: Art conservators use the handheld camera to directly scan expensive paintings, antiquities, or sculptures without having to move them, helping to analyze covered old paint layers and devise accurate restoration plans.
