ASD - FieldSpec - 4 Standard-Res Spectroradiometer

The go-to standard for trusted portable field spectroscopy.

The FieldSpec 4 Standard-Res spectroradiometer, with 10 nm SWIR resolution is perfectly suited for characterizing spectral features with a resolution of 10 nm to 50 nm, which covers the technical requirements of most field researchers. The FieldSpec 4 Standard-Res spectroradiometer has long been the industry’s go-to workhorse instrument for trusted field spectroscopy and the scope of potential applications is broad.

The 3 nm VNIR, 10 nm SWIR spectral resolution of the FieldSpec® 4 Standard-Res portable spectroradiometer is ideal for characterizing spectral features with a resolution down to 10 nm. The FieldSpec 4 Standard-Res is well positioned to meet a majority of the technical needs of field researchers who require dependable and trusted results from a field portable spectroradiometer.

The FieldSpec 4 Standard-Res portable spectroradiometer is the right choice for a wide range of remote sensing applications, including multispectral sensor ground truthing and calibration, agricultural analysis, and snow and ice studies. In addition to being a world class spectroradiometer, the FieldSpec 4 Standard-Res is equally suited to serve as a rugged, portable spectrometer for accurate contact reflectance or non-solar stand-off measurements.
