and more…
Rapid — a scan time of approximately 100 milliseconds allows for more data in less time.
Ultra Rugged — the FieldSpec® 3 is built to withstand extreme conditions, including intense temperatures, shock and vibration, and other situations common to field research.
Portable — when carried on your back in the ASD Ergonomic Propack and using battery power, the light weight FieldSpec® 3 is ready to go where you need to go, when you need to go.
Flexible — with non-slip rubber feet for integration into custom transport platforms and the improved ASD Ergonomic Propack, the FieldSpec® 3 is ready for the field, mountains, the desert, the arctic, or just about anywhere your application takes you.
Wireless — the wireless connection allows for remote control of your data collection up to 150 feet away* (Ethernet port also standard on all systems).
Built-In Diagnostics — the FieldSpec® 3 provides an unprecedented diagnostic package featuring the ASD FiberChecker™.
Automated Data Collection — the LabVIEW® interface expands the power and capabilities of ASD’s RS3™ software, enabling automation of data collection and ease of use for a wide variety of applications.
Collect more data, from more sites, in less time!
Researchers from universities, governments and private research laboratories, and other research institutions rely on the portability and flexibility of the FieldSpec® family of instruments for their spectroscopic needs.

Other Models in the FieldSpec® Line:
FieldSpec® 3 Max (350-2500 nm)
The benchmark FieldSpec® 3, now with optimized grating set and Select Test Option for the maximum signal to noise levels.
FieldSpec® 3 Hi-Res (350-2500 nm)
The high-resolution alternative in the FieldSpec® 3 line is ideally suited for mineral/soil analysis, and other applications requiring higher resolution spectra.
FieldSpec® 3 JR (350-2500 nm)
This lower resolution alternative to the FieldSpec® 3 is well suited for many plant physiology, agronomy and forestry applications.
FieldSpec® 3 VNIR (350-1050 nm)
A fully upgradeable FieldSpec® 3 model that makes it possible for users with a lower budget to purchase the instrument and then upgrade the spectral range as budget allows.
These are the most common designs, but with the Goetz Spectrometer inside, the modular design of our FieldSpec® line of advanced spectroradiometers allows for customization to fit your specific application and budgetary needs.
