ASD FieldSpec Pro System

Features

The Facility has three Analytical Spectral Devices (ASD) FieldSpec Pro spectroradiometers available for loan. ASD's flagship model, the FieldSpec Pro is the industry standard for a wide range of challenging Remote Sensing applications, and offers superior signal-enhancing features and high resolution with a 350 - 2500 nm spectral range. The instrument is backpack-mounted to enable the collection of spectral measurements wherever you want to go. Acquiring field data has never been faster or easier!

Designed to collect solar reflectance, radiance and irradiance measurements, these instruments are ideal for applications in mining, optical remote sensing, oceanography, forestry, plant physiology and geology. With exceptional portability, the FieldSpec Pro is compact and easy to set up, letting you collect more data from more sites in less time.

A new addition to the Facility are two Contact Reflectance Probes, which can be fixed as a foreoptic attachment to the fibre-optic cable to provide all-weather spectral capabilities for the FieldSpec Pro. This attachment brings the ASD FieldSpec in line with other instruments such as the PIMA SP, allowing the user to collect high quality reflectance spectra over a range of surfaces, with improved signal to noise ratios, thus making it ideal for spectral library creation across a range of applications.
