CHN SPEC FS-50/120 Drone-borne Multispectral Camera (400~1000nm, 120 Spectral Channels)

CHN SPEC FS-50/120 Drone-borne Multispectral Camera (400~1000nm, 120 Spectral Channels)

CHN SPEC FS-50/120 multispectral camera is a pinnacle spatial and spectral data acquisition solution, optimally designed for integration on industrial unmanned aerial vehicle (UAV) platforms (such as DJI Matrice 300 RTK, M350 RTK). With the capability to decompose the light spectrum into 120 independent spectral channels, the device scans and records highly detailed “spectral barcodes” of any object on the ground, delivering superior quantitative analysis compared to conventional 5-6 channel multispectral cameras.

Key Feature Highlights

Absolute data accuracy: The system integrates a real-time ambient light radiometric calibration module (Ambient Light Sensor), which standardizes the captured image data regardless of changing cloud cover or harsh sunlight during the flight.

Smart operation (Plug-and-Play): Thanks to deep integration with the DJI ecosystem, operators can plan flight missions and control camera parameters directly on the ground control station application, while visually previewing real-time spectral graphs.

Closed-loop analysis software ecosystem:

• FIGSPEC UAV: Configures flight data acquisition parameters.
• FIGSPEC Merge: Automatically stitches flight strips into complete multi-channel orthomaps.
• FIGSPEC Studio: An advanced analytical library that supports instantaneous calculation of vegetation health indices (NDVI, NDRE, EVI, OSAVI…) and predictive model deployment.

Typical Practical Applications

Possessing 120 continuous scanning spectral channels, the CHN SPEC FS-50/120 is a powerful instrument for analytical tasks requiring high sensitivity:

• Smart Agriculture & Crop Breeding: Quantitatively analyzes nitrogen (N), phosphorus (P), and potassium (K) deficiencies or surpluses in crops; detects early-stage disease outbreaks or pest infestations long before leaves change color. Assists research institutes in classifying and evaluating the vigor of experimental crop varieties.
• Forestry Surveying & Classification: Counts and accurately classifies individual tree species in natural or protected forests based on their distinct spectral reflectance characteristics. Surveys forest biomass stocks.
• Environmental Monitoring & Water Quality: Measures concentrations of total suspended solids, dissolved organic matter, and provides early detection of toxic harmful algal blooms (HABs) in river systems, lakes, freshwater reservoirs, or aquaculture zones.
• Geology & Mining: Rapidly identifies mineral outcroppings and maps surface soil and rock distributions based on absorption spectra in the near-infrared (NIR) band.
