Spectroradiometer


Our spectroradiometers measure radiation with 1/2-nanometer bandwidth resolution.

REFLECTANCE

Dr. Glen Ritchie of the University of Georgia has used Model PS-100 to take reflectance measurements in cotton fields and estimate defoliation. Chlorophyll gives plant leaves a reflectance spectrum characteristically different from that of soil. Reflectance measurements can be reported in
µmol m-2 s-1, W m-2, or as a relative value.
