  • FieldSpec 4 Wide-Res Field

    High resolution spectroradiometer

    3nm VNIR, the 30 nm SWIR spectral resolution of the FieldSpec ® 4 Wide-Res Field field spectroradiometer, is an economical solution for the analysis of any material with broad spectral characteristics.

     

    A robust field spectrometer for accurate contact reflectance or non-solar energy measurements.

    General studies of vegetation and water column analysis are common areas of application that are associated with broader spectral characteristics.

    This instrument is available at a significantly lower price than other FieldSpec 4 models, making it an attractive option when budgets are tight.

    SWIR 1 1,5 X10 -9   W / cm 2 / nm / sr @ 1400 nm
    SWIR 2 2,8 X10 -9   W / cm 2 / nm / sr @ 2100 nm
    weight 5,44 kg (12 lbs)

    The FieldSpec 4 Wide-Res field spectroradiometer can be used for many of the same applications as the Standard-Res model, although the characterization of material with sharper spectral characteristics is less accurate. FieldSpec 4 Wide-Res is not recommended for the analysis of materials and compounds with narrow or sharp geological spectral characteristics in the SWIR range, such as alteration mineralogy or atmospheric / gas studies.

    Due to its wider optical slot, the FieldSpec Wide-Res field spectroradiometer provides the best signal yield of any FieldSpec spectroradiometer. High performance benefits measures taken in low light conditions.

    In addition to being an economical field spectroradiometer, FieldSpec 4 Wide-Res also works well as a robust field spectrometer for accurate contact reflectance or non-solar energy measurements.
