Abstract

L'invention concerne un module séparateur de faisceau pour microscopes, notamment pour microscopes opératoires servant à observer des objets le long d'un axe principal (37). Ce module dispose de plusieurs trajets de faisceaux partiels stéréoscopiques (6, 7, 10), par l'intermédiaire desquels des données peuvent entrer et sortir par réflexion. Ce module est compact et de faible hauteur de sorte que l'observateur peut travailler dans des conditions ergonomiques optimisées.
