Overview
The iSpecField-HH Handheld Field Spectroradiometer from LiSen Optics is designed for field spectroscopy, remote sensing, and environmental monitoring applications. Lightweight and easy to operate, it delivers rapid spectral acquisition and reliable data quality in a compact handheld platform.
Depending on the model, the system offers a 5-inch or 7-inch industrial-grade color touchscreen, integrated camera, GPS, laser pointer, automatic optical-shutter control, remote triggering, and automated acquisition modes with user-defined scan counts and automatic data saving. It is built for efficient, repeatable measurements in demanding field environments.
Typical Applications
Embedded Spectral Acquisition Software
The embedded software supports rapid spectral acquisition, camera-assisted field documentation, real-time vegetation-index calculations, and live display of measurement status and environmental metadata.
