Systems for outside spectral data
A field spectrometer must deliver stable spectra under real conditions. Variable sunlight, dust, and long deployments make optics, calibration, and metadata critical. That is why field spectroradiometry is used for remote sensing validation and environmental monitoring for long campaigns.
Outdoor measurements demand both strong spectral performance and radiometric reliability. In changing sunlight and temperatures, effects like dark current, temperature dependence, and cosine response can shift results if they are not handled in the instrument design.
A second key factor is stable measurement geometry. For long time series, defined viewing angles and robust capture of downwelling illumination help keep datasets comparable across hours, seasons, and sites.
Third, field work is won or lost by station readiness. Weatherproof housings, low power operation, day and night energy saving, onboard storage, and reliable interfaces determine whether a system runs unattended for weeks instead of needing constant attention.
All of these are the focus of JB Hyperspectral’s RoX, NoX, and FloX, which are built for permanent outdoor installation with features such as rugged waterproof cases, a 12 V battery or solar supply, and autonomous operation with long duration SD logging.
