CHN SPEC FS-620 Multispectral Camera (4 Multispectral bands + 1 RGB + 1 Thermal Infrared (LWIR) band)

The CHN SPEC FS-620 multispectral camera is a breakthrough spatial data acquisition solution. By combining the power of 4 multispectral bands, 1 high-resolution RGB optical lens, and 1 thermal infrared (LWIR) sensor into a single module, the CHN SPEC FS-620 provides comprehensive analytical capabilities. This device allows users to observe visual details visible to the naked eye, assess vegetation health via spectral indices, and map temperature distribution in just a single flight.

Outstanding Features of CHN SPEC FS-620

Superior “6-in-1” sensor system: The device simultaneously collects data through 6 independent lenses:

• 1 RGB Band: Provides high-resolution true-color imagery for visual mapping and 3D modeling (Photogrammetry).
• 4 Multispectral Bands: Typically including Green, Red, Red Edge, and Near Infrared (NIR) bands for detailed analysis of crop biological indices (such as NDVI, NDRE).
• 1 Radiometric Thermal Infrared (LWIR) Band: Measures and maps absolute surface temperatures, detecting areas with thermal anomalies.

Perfect image synchronization: All 6 sensors are time-synchronized to trigger captures simultaneously. This ensures that the optical, multispectral, and thermal image layers can be superimposed with absolute precision during post-processing.

Integrated Downwelling Light Sensor (DLS): The FS-620 typically comes with an upward-facing light sensor module to record ambient lighting conditions throughout the flight. This data enables automatic reflectance calibration, ensuring spectral data remains accurate regardless of shadows or cloud cover.

Ultra-lightweight design, optimized for UAVs: With its light weight and streamlined aerodynamic design, the camera is easily mounted on most current commercial and industrial drones without significantly reducing flight time.

Diverse connection protocols: The device supports a variety of standard connection interfaces (such as SkyPort, PWM, Serial, Ethernet), allowing deep integration into the flight control system to receive GPS/RTK coordinates and trigger automatic image capture along the flight path.
