The ASD FieldSpec® 4 Hi-Res is a high resolution spectroradiometer designed for faster, more precise spectral data measurements for a wide array of remote sensing applications.
The 3 nm VNIR, 8 nm SWIR spectral resolution of the ASD FieldSpec® 4 Hi-Res spectroradiometer provides superior spectral performance across the full range solar irradiance spectrum (350 – 2500 nm). The enhanced spectral resolution in the SWIR range (1000 – 2500 nm) is particularly useful for detecting and identifying compounds with narrow spectral features in the longer wavelengths such as alteration mineralogy and gases for atmospheric analysis.
Additionally the 8 nm resolution meets or exceeds the spectral resolution of most hyperspectral sensors making the ASD FieldSpec 4 Hi-Res spectroradiometer an excellent choice for sensor validation and calibration, as well as ground truthing and building spectral libraries.
Like all ASD FieldSpec spectroradiometers, the ASD FieldSpec 4 Hi-Res can be used as a high resolution spectrometer for very accurate contact reflectance measurements.
