  • 详细信息

Field Portable Spectroradiometers

The SVC HR-640i provides high quality spectral data across the full spectral region from 350 nm to 2500 nm. The spectral resolution in the SWIR region is suitable for many applications in forestry, agriculture and environmental assessment. The ability to set parameters and review data on the touch screen makes this instrument extremely easy to use.


The internal GPS and camera add critical information to the spectral signatures and can save countless hours during the data analysis. The ability to receive this real time field data and helps guide the user towards making better measurements. Stored downwelling sensor allows the user to revisit the reference panel should a change in irradiance be detected. The use of 100% linear array detectors ensures excellent wavelength stability, while the thermoelectrically cooled InGaAs and extended InGaAs detectors provide superior radiometric stability. This instrument supports many agricultural applications”
