Other Models in the FieldSpec® Line:
FieldSpec® 3 (350-2500 nm)
ASD's flagship model, the industry standard for a wide range of challenging Remote Sensing/Earth Science applications, offers superior signal-enhancing features and high resolution with a 350 nm - 2500 nm spectral range.
FieldSpec® 3 Hi-Res (350-2500 nm)
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.
