The Spectral Evolution NaturaSpec™ 3500 is a versatile, field-portable spectroradiometer that delivers high-quality spectral measurements across the full 350-2500 nm wavelength range. Designed for applications such as environmental monitoring, precision agriculture, vegetation studies, and ground-truth validation, it combines research-grade performance with rugged field usability.
Featuring solid-state diode-array optics with no moving parts, NIST-traceable calibration, Bluetooth connectivity, and user-replaceable fiber optics, the NaturaSpec 3500 offers an excellent balance of accuracy, reliability, and cost-effectiveness, making it a compelling alternative to many higher-priced field spectroradiometers
The Spectral Evolution NaturaSpec™ 3500 is a versatile field-portable spectroradiometer designed for remote sensing, environmental monitoring, precision agriculture, forestry, and ecosystem research. Covering the full 350-2500 nm spectral range, it provides reliable UV, visible, near-infrared (NIR), and short-wave infrared (SWIR) measurements in a compact and rugged platform suitable for demanding field environments.
Within the NaturaSpec product family, the NaturaSpec 3500 occupies an attractive position for organisations seeking high-quality spectral data without the investment required for the higher-performance NaturaSpec Plus or NaturaSpec Ultra models. Its combination of full-range spectral coverage, solid-state diode-array optics, and field-ready operation makes it particularly well suited for routine ground-truthing, vegetation analysis, soil characterisation, and environmental research applications.
The NaturaSpec 3500 delivers a strong balance of spectral resolution, portability, and ease of use, allowing researchers and practitioners to collect laboratory-quality spectral measurements in the field while maintaining a lower total cost of ownership than many premium research-grade systems. This makes it an attractive choice for universities, government agencies, environmental consultancies, and commercial operators looking for a practical and dependable full-range spectroradiometer.
