It is a high-performance, portable instrument used for field-based spectral measurements. It captures data across a broad wavelength range, from 350 to 2500 nm, covering the visible, near-infrared (NIR), and shortwave infrared (SWIR) regions. The FieldSpec 3 is commonly used in applications like remote sensing, environmental monitoring, and geological surveying to analyze materials, vegetation, and land surfaces. Its rugged design allows for reliable, precise data collection in challenging outdoor environments.
