AvaField Series Portable Hyperspectral Surface Spectrometers
The AvaField series portable hyperspectral spectrometer (field spectral radiometer) is a new product of Avantes company in the Netherlands, suitable for applications in various fields such as remote sensing measurement, crop monitoring, forest research, oceanography research, mineral exploration, etc. The AvaField series ground spectrometers have the characteristics of high cost-effectiveness, fast and accurate measurement, simple operation, and easy portability. They are equipped with feature rich software packages, and can be used for radiometric and photometric measurements in addition to reflectance and transmittance measurements.
Avantes, a Dutch company, has developed a testing system for hyperspectral ground spectrometers using unmanned aerial vehicles. This system achieves large-scale detection with minimal constraints, while also quickly and finely obtaining data, effectively combining the advantages of aerial remote sensing and near earth remote sensing; Applied to fields such as agriculture, forestry, geology, oceanography, meteorology, hydrology, military, and environmental protection.
