Abstract
The present disclosure is directed to a microscope tube including a ocular optical path including a collecting lens, a deflecting optical system, a binocular unit and an eyepiece, wherein light emitted from an objective enters through the collecting lens and is transmitted into the binocular unit via the deflecting optical system to allow a human eye to observe by the eyepiece at a visual angle, wherein the deflecting optical system includes a fixed deflecting optical components group and a rotatable deflecting optical components group located after the fixed deflecting optical components group along a light transmission path, the visual angle being adjustable by the rotatable deflecting optical components group, and light emitted from the objective reaching the binocular unit after an even number of reflections of at least four times by the deflecting optical system.
