High resolution spectral data from a ruggedized field-portable spectroradiometer The 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 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 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 FieldSpec 4 Hi-Res can be used as a high resolution spectrometer for very accurate contact reflectance measurements.
