FieldSpec 4 Hi-Res NG NIR spectroradiometer

ASD Inc. has introduced the next generation of their FieldSpec line of spectroradiometers, the FieldSpec 4 Hi-Res NG, which provides enhanced spectral resolution to support accurate calibration and image classification analysis with the next generation high spectral resolution hyperspectral sensors.

“With the FieldSpec 4 Hi-Res NG, ASD is providing the ground-based spectral resolution necessary to take full advantage of the next generation high-resolution hyperspectral imaging systems such as AVRIS-NG and HySpex ODIN-1024”, said Brian Curtiss, CTO of ASD Inc. “The instrument provides the required spectral resolution along with the level of spectral detail that is essential for sensor validation and calibration, as well as ground truthing and building spectral libraries.”

The FieldSpec 4 Hi-Res NG incorporates ASD’s fast spectrum integration speeds and graded index InGaAS photodiode SWIR technology, with new and enhanced next generation SWIR optics. The FieldSpec 4 Hi-Res NG provides high spectral resolution in the SWIR bands, high performance for rapid field measurement collection, and a small spectral sampling interval with 1875 measured wavelengths over the full 350–2500 nm spectral range.
