Abstract

La présente invention concerne une unité de filtre optique avec une entrée et une sortie et un élément modifiant les ondes disposé entre l'entrée et la sortie. Afin d'obtenir une unité de filtre optique avec laquelle au moins une propriété de l'élément modifiant les ondes est moins fortement affectée lors du passage à travers l'unité de filtre, on dispose conformément à l'invention dans la direction optique entre l'élément modifiant les ondes et la sortie, un élément de compensation qui compense au moins en partie au moins une propriété de l'élément modifiant les ondes.
