RS-5400 Spectroradiometer

High-Resolution, High-Sensitivity UV-VIS-NIR Spectroradiometer


The RS-5400 provides high resolution/high sensitivity in a portable spectroradiometer for field use. The RS-5400 has a spectral range of 350-2500nm and three high-density photodiode array detectors: 1024 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 features a rugged chassis, no moving optical parts, and metal-clad fiber optic cable that’s easily replaceable. It features one-touch operation with auto-dark current and auto-exposure. Communications include wireless Bluetooth and USB connections. It includes DARWin™ SP Data Acquisition software that is Windows 7/8/10 compatible and saves all files as ASCII.

The RS-5400 running EZ-ID™ mineral identification software is well-suited for mineral identification including identification of clays in soil.

EZ-ID provides pattern matching software that matches your target samples against three libraries of known samples for more than 1000 minerals: the USGS, SpecMIN, and GeoSPEC libraries.
