Abstract

We report herein an hybrid (diffractive-refractive) lens triplet showing quasi-wavelength-independent optical Fourier transform capabilities. The wavelength compensation carried out by our novel optical design is exact for the axial position of the Fourier transform of the input. Nevertheless, a very low residual transversal chromatic aberration remains. Results of laboratory experiments will be shown.
