Abstract

L'invention concerne un tube ergonomique (30) d'un microscope (1). Le tube (30) est pourvu d'une tête binoculaire (20). Un élément déflecteur (5), placé dans le tube (30), est associé à un miroir déflecteur (18). Le miroir déflecteur (18) est placé derrière le trajet optique (5) vu de la position de l'utilisateur (17). Un système lentille de tube (11) unique est placé dans le trajet optique (16) du tube. Une modification de l'inclinaison du trajet optique (21) de la tête binoculaire d'une valeur α par rapport à l'horizontale (H) entraîne une modification de la position du miroir déflecteur (18) d'un angle α/2.
