CHN SPEC FS-19M Short-Wave Infrared Hyperspectral Camera (900~1700 nm, 2400 fps)

CHN SPEC FS-19M Short-Wave Infrared Hyperspectral Camera (900~1700 nm, 2400 fps)

The CHN SPEC FS-19M Hyperspectral Camera (SWIR Hyperspectral Camera) is a state-of-the-art optical signal acquisition device operating in the short-wave infrared band (900 nm – 1700 nm). With a powerful frame rate of up to 2400 fps (frames per second), the FS-19M is an ideal choice for Machine Vision and industrial automation systems. This device ignores external color characteristics to “see through” the material structure, extract chemical compositions, and detect hidden impurities right on conveyor belts moving at high speeds.

Outstanding Features

• High acquisition speed (2400 fps): The scanning speed of 2400 frames per second helps the FS-19M easily keep up with the pace of high-speed industrial sorting conveyors. The machine collects image data continuously, smoothly, and without blur, meeting the strict standards of real-time automation systems.
• Short-wave infrared band (900 – 1700 nm): SWIR rays have a special interaction capability with the molecular structure of materials, especially components containing water, fat, protein, and polymer bonds. This helps the camera easily identify and quantify the internal chemical structure that the naked eye cannot observe.
• Solution for hard-to-sort materials (Black plastic): The biggest limitation of conventional optical cameras is the inability to sort black plastic because the black color absorbs visible light. In contrast, the FS-19M uses SWIR infrared waves to extract the distinct “spectral fingerprint” of each type of black plastic (PET, PP, PE…), providing a breakthrough solution for the recycling industry.
• “See-through” capability: The SWIR band can penetrate some opaque or semi-transparent materials such as Silicon semiconductor wafers and thin plastic packaging shells. This turns the device into an optical X-ray imaging tool to inspect internal defects.
• 3D data block (Hypercube) export: The machine records multidimensional hyperspectral data blocks (X, Y, λ), providing perfect foundational data for integration with Artificial Intelligence (AI), Machine Learning, and Principal Component Analysis (PCA) algorithms to serve immediate defect rejection decision-making.

Practical Applications

With a speed of 2400 fps and the SWIR waveband, the CHN SPEC FS-19M is an indispensable puzzle piece in industrial sorting and R&D systems:

Waste Management & Recycling: Automating the sorting process of various polymers and plastics on conveyor belts; particularly effective in identifying and separating scrap black plastics.

Food & Agricultural Product Quality Control:

• Measuring moisture and fat distribution in meat, fish, and grain products.
• Detecting dangerous foreign objects mixed in food (such as small stones, plastic shells, wood, glass shards) because their SWIR spectral graphs are completely different from organic biomass.

Semiconductor & Electronics Industry: Seeing through Silicon wafers or Solar cells to find micro-cracks, air bubbles, or impurities sandwiched between material layers.

Pharmaceuticals & Biomedicine: Analyzing the uniformity of active ingredients in tablets through plastic blister packs; checking the homogeneity of medicinal raw material mixtures on an industrial scale.
