Push broom hyperspectral scanner

The L-EOS is an infrared push broom hyperspectral system optimized from 0.9 up to 2.8 µm. Using a totally reflective spectrometer at its core, it has fewer interfaces, thus less light losses, no chromatism and very low aberrations. It is combined with Photon etc.’s scientific-grade infrared cameras and objective lenses specifically designed for infrared spectroscopy. 

The most important added value is the possibility to customize the instrument to specific applications. Our broad expertise covers various applications going from geology to material sorting, recycling and many others. Its 4 stages TE cooling at either -50°C or -80°C offers a longer lifetime than other cooling systems and less maintenance. Its robustness makes it industry-ready.
