Abstract

Un composant optique (10) combine une efficacité de sélection spectrale avec la possibilité d’utilisation dans un dispositif de détection (1) à large champ optique d’entrée. Le composant est adapté en particulier pour être incorporé dans un système autodirecteur de guidage d’engin autopropulsé. Il comprend un filtre (13), notamment de type filtre interférentiel, qui est disposé entre deux lentilles sans interstice entre ledit filtre et chacune des deux lentilles. Figure d’abrégé : Figure 1
