The Gold Standard in Field Spectroradiometers
ASD pioneered the science of field spectroscopy over 25 years ago and continues to lead the industry with the world's most trusted field-portable UV/Vis/NIR/SWIR spectroradiometers covering the full solar reflected spectrum.
The ASD FieldSpec 4 line of full-range spectroradiometers delivers the fastest and most accurate spectral field measurements available from any commercial field-portable spectroradiometer. Continued enhancements to core instrument spectrometers and other critical components have dramatically improved overall performance, signal, and integration speeds compared to earlier models.
ASD FieldSpec 4 spectroradiometers are designed specifically around the challenges researchers face when collecting spectral measurements in the field.
