Mjolnir S-620
Shortwave Infrared Hyperspectral — 970 to 2,500 nm, Cooled Detector
The Mjolnir S-620 is the SWIR member of the Mjolnir series. Like its VNIR sibling, it combines a small form factor and low mass with high-performance specifications and scientific-grade data quality — opening the shortwave infrared (970–2500 nm) for mineralogy, moisture, and material identification from a UAV.

The Chemistry of the Scene
Cooled SWIR sensing reveals mineral, moisture, and material signatures the visible spectrum can't — at scientific-grade quality.
Shortwave Infrared 970–2500 nm
The SWIR range unlocks mineralogy, moisture, and chemical signatures that are invisible to VNIR sensors — ideal for exploration and material ID.
Cooled MCT Detector
A cooled detector drives a peak SNR over 2000 and a 16-bit dynamic range — clean spectra even in low-signal SWIR bands.
Scientific-Grade SWIR
620 spatial pixels and 300 spectral channels at 5.1 nm sampling through an f/1.9 spectrograph — precise, repeatable data.
Lightweight Mjolnir Form Factor
Under 4.5 kg and under 50 W in the same compact body as the rest of the series — UAV, gimbal, or tripod deployable.
