The L-EOS Push broom hyperspectral scanner system from Photon etc. Optimised for 900-2800nm, this fully customisable system is ideal for spectroscopy applications.
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.
There are three models of the L-EOS spanning the spectral range 900-2800nm:
L-EOS 1.7 covering spectral range 900-1650nm and incorporating Photon etc’s ZephIR 1.7 or Alizé 1.7 InGaAs camera
L-EOS 2.5 covering spectral range 900-2500nm and incorporating Photon etc’s ZephIR 2.5 MCT camera
L-EOS 2.8 covering spectral range 1000-2800nm and incorporating Photon etc’s ZephIR 2.9 MCT camera
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.
