ASD FieldSpec3 Spectroradiometer

Tags: calibration

FieldSpecĀ® 3 is a field portable, precision radiometer with a spectral range (350- 2500 nm) and rapid data collection (1/10th of a second per spectrum). The wireless connection allows for remote control of data collection up to 50m away. It is designed to collect solar reflectance, radiance and irradiance measurements.
