Abstract
We report, to our knowledge for the first time, the achievement of analogue integrated Fresnel lenses having very high performances, and the association of two such lenses. Focusing efficiencies higher than 60% have been measured on that component with a background noise lower than ¿27 dB at 1° off-axis in the focal line.
