ASD FieldSpec | Field Portable Spectroradiometers

The ASD FieldSpec range is ideal for users requiring maximum sensitivity in outdoor and remote sensing applications.

Key features:

Superior signal-to-noise ratio: Twice as sensitive as TerraSpec and LabSpec, making it the best choice for working with limited natural light sources like sunlight
Permanent fiber optic cable: Factory-installed to eliminate signal loss at junction points, ensuring optimal performance
Recommended for sunlight use: Essential for reliable data collection under natural light
Ideal for remote sensing: Used for ground-truthing overflight sensors, matching satellite data, and ensuring accurate spectral measurements under varying environmental conditions
