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.
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.

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.
