The spectroradiometer HR-768i from Spectra Vista (SVC) is a field instrument covering 350 – 2500 nm for reflectance and radiance measurements. It uses 768 Linear Array (Si, InGaAs, Extended InGaAs) with FWHM 3.5 nm @ 700 nm / 16 nm @ 1500 nm / 14 nm @ 2100 nm, weighing 8.5 lbs (3.8 kg), for vegetation, soils, and calibration work.
Remote-sensing scientists use this spectroradiometer when they need portable 350 – 2500 nm spectra with the HR-768i resolution.
Overview: Full-range 350-2500 nm field spectroradiometer integrating 768 channels, onboard GPS, and superior radiometric stability.
