Abstract
The multispectral filter for an image detection device comprises a prismatic plate () comprising a first internal face () and a second external face (), the first and the second faces () being inclined with respect to one another by an angle β, and comprises at least two different spectral bands () deposited either on the first or the second face () of the prismatic plate (), the various spectral bands () being spaced a predetermined distance (D) apart. Application to multispectral imagers, in particular to Off Axis imagers. This filter allows the suppression of the ghost images (or spurious echoes) generated at the focal plane of a multispectral imager.
