Abstract
L'invention a pour objet un interf eromètre optique à deux ondes d efinissant deux chemins de longueurs optiques diff erentes et comportant au moins un p eriscope s eparateur.Conform ement à l'invention, l'interf eromètre comporte, sur le chemin court de l'interf eromètre, une lame de compensation taill ee dans un verre de même nature que les p eriscopes s eparateurs et ayant pour epaisseur la diff erence des epaisseurs de verre des p eriscopes s eparateurs travers ees respectivement par chacune des ondes.L'invention est applicable aux dispositifs de transmission par fibres optiques et multiplex es en longueur d'onde.
