RS-5400 Portable Spectroradiometer

High Resolution Field or Lab Spectroradiometer for Remote Sensing

The RS-5400 provides high resolution/high sensitivity in a portable spectroradiometer for field or laboratory use. The RS-5400 has a spectral  range of 350-2500nm and three high density photodiode array detectors: 512 element UV-enhanced Silicon array for 350-1000nm; 512 element Extended InGaAs photodiode array for 1000-1900nm; and a 512 element Extended InGaAs photodiode array for 1900-2500nm. The unit is lightweight and runs off a 100-240V AC Universal 50-60Hz power supply or Lithium-ion batteries.

The RS-5400 provides high resolution and high sensitivity for  remote sensing applications for in situ field measurements. Applications include:

  • Vegetation studies
  • Environmental research
  • Soil analysis, mapping and profiling
  • Ground truthing
  • Geological remote sensing
  • Solar radiance and irradiance research
  • Species identification
  • Lab applications including materials identification

The RS-5400 is designed for field work with a rugged chassis, no moving optical parts, and rugged metal clad fiber optic cable that’s field replaceable. It features one touch operation with auto-dark current and auto-exposure. Communications include wireless Bluetooth and USB connection. It includes DARWin SP Data Acquisition software that is Windows 7/8/10 compatible and saves all files as ASCII.
