The HG-iSpectra 2500 portable full-range field spectroradiometer features a ruggedized optical path system paired with a cooled detector. Combined with advanced spectroscopy algorithms, it ensures exceptional wavelength accuracy and high spectral resolution during outdoor surface feature measurements. It is widely applicable across diverse fields such as resource investigation, agricultural remote sensing, precision agriculture, crop yield estimation, forestry research, ocean sciences, and mineral identification. With a wide wavelength response range from 350nm to 2500nm, the complete unit weighs only 3.8kg. In addition to offering multiple measurement modes, this high-performance full-range field spectroradiometer provides various automated processing functions, including real-time automatic dark current correction, automatic spectral averaging, and automatic calculation of spectral reflectance. Beyond fulfilling conventional ground-level feature spectral measurements, the remarkably light and compact build allows the HG-iSpectra 2500 to be mounted on lightweight, small UAV platforms for executing large-scale spectral survey tasks. Via a customized quick-mount kit, field operators can easily complete the entire system installation and debugging process within minutes. The accompanying software package features a simple, user-friendly, yet powerful interface that can be tailored and expanded for specialized application needs, delivering a true one-stop solution for field spectral measurements.
