Overview

The iSpecField-(W)NIR-HH family combines VNIR/SWIR spectral sensing with synchronized target imaging in a handheld field instrument. Two configurations cover 350-1700 nm and 350-2500 nm, supporting field measurements for mineral exploration, geological mapping, soil analysis, environmental monitoring, and related remote-sensing applications.

Each model uses a fixed holographic-grating optical design and pairs a 2048-pixel CMOS detector with a 256- or 512-pixel InGaAs detector. An integrated 8 MP camera records the measurement target alongside the spectrum, helping field teams keep spectral data and site imagery together during acquisition and review.

Automatic shutter control, dynamic compensation, and one-touch measurement simplify field workflows. The IP5X housing and fully sealed IP6X optical core are designed for dependable operation in demanding outdoor environments.
