Description

Worldwide first underwater hyperspectral imaging system

The U285 UW is our first solution for full-frame imaging spectroscopy underwater. The device features minimum of 5 meter water resistance for a dive duration of 1 hour.

The U285 UW is based on our industrial grade of the Q285 QE. It is the first of its kind full-frame, non-scanning, imaging spectrometer solely designed for underwater use. Our technology combines the simplicity of a point-and-shoot camera with the precision of hyperspectral imaging.

Full-frame hyperspectral imaging

The goal of our development was an easy-to-handle imaging spectrometer with no need for scanning (like push-broom technology) or image combination after fast filter shifts. Instead of the slit of a push-broom scanning device we use a spatial grid which images two-dimensional data points trough the spectral apparatus onto the CCD.
Recalculation of the interwoven spatial and spectral information gives us direct access to the hyperspectral cube with every frame captured. This process takes as little as 1/1000 of a second. Thus there are no moving artifacts, no hassle with translation stages and no restrictions in speed.
All that technology was packed into a waterproof, dustproof and shock-resistant housing that guarantees long term stability and lets you use the system where you need it.
With this technology you get unique advantages above all available systems on the market, which enables new and outstanding applications.
