The wide optical slit the FieldSpec 4 Wide–Res spectroradiometer provides the highest signal throughput and offers the best signal to noise performance of any FieldSpec model. These high throughput characteristics also benefit field measurements taken in less than optimal illumination conditions.
The 30 nm SWIR resolution of the FieldSpec 4 Wide-Res spectroradiometer makes it an ideal fit for applications such as vegetation analysis and vegetation indices that are characterized by broad spectral features. This instrument is also available at a significantly lower price point than other FieldSpec models, which makes it an attractive option when budgets are tight.
The 3 nm VNIR, 30 nm SWIR spectral resolution of the FieldSpec® 4 Wide-Res field spectroradiometer, is a cost-effective solution for the analysis of any material with broad spectral features. General vegetation analysis and water column studies are common application areas that are associated with broader spectral features.
The FieldSpec 4 Wide-Res field spectroradiometer can be utilized for many of the same applications as the Standard-Res model although the characterization of material with sharper spectral features will be less precise. The FieldSpec 4 Wide-Res is not recommended for the analysis of materials and compounds with narrow or sharp geological spectral features in the SWIR range such as alteration mineralogy or atmospheric/gas studies.
Because of its wider optical slit the FieldSpec Wide-Res field spectroradiometer delivers the best signal throughput of any FieldSpec spectroradiometer. High throughput benefits measurements taken in low illumination conditions.
This instrument is available at a significantly lower price point than other FieldSpec 4 models, which makes it an attractive option when budgets are tight.
In addition to being a cost-effective field spectroradiometer, the FieldSpec 4 Wide-Res also functions well as a rugged, field spectrometer for accurate contact reflectance or non-solar stand-off measurements.
