Portable Spectroradiometer Line

Analytik is pleased to announce the release of the FieldSpec 4 line of portable, full-range spectroradiometers from ASD, Inc. With this launch, ASD is continuing its tradition of setting industry standards for ground truthing and remote sensing measurement technologies. The field collection of radiometric and reflectance spectra of intact materials

(often referred to as ground truth data collection) is essential for interpreting unknown materials in multi-spectral and hyperspectral remote sensing data, and validating sensor performance. Since sample removal for lab study often destroys the sample's surface properties, and because lab study is impractical for many large natural surfaces, researchers need a reliable field device capable of providing laboratory-quality, field measurements with illumination and viewing geometry equivalent to a satellite or aircraft sensor.

The FieldSpec 4 line has been designed for faster, more precise spectral data collection. The powerful FieldSpec 4 line of fullrange (350-2500nm) spectroradiometers provides researchers concerned with speed, the ability to cover more ground faster while enjoying the same high data quality. Ultimately, FieldSpec users can cover twice the area in a half of the time thanks to the improvements in the SWIR 1 and 2 regions (1000-2500nm). For applications requiring the highest possible precision, the new spectrometer configuration provides double the signal-to-noise performance. This results in much more precise spectral data with no increase in measurement time. Researchers who are looking at materials with features at the longer wavelengths will especially benefit from these improvements. The line consists of three models, the FieldSpec 4 Standard-Res, a general purpose remote sensing spectroradiometer suitable for a wide range of applications including hyperspectral image interpretation and validation. The FieldSpec 4 Hi-Res is well-suited to geologic and other applications that require definition of narrow spectral features, especially in the longer wavelengths. The FieldSpec 4 Wide-Res model is perfect for multispectral and other areas of research involving materials with broad spectral features such as plant physiology.
