Abstract
A compact microscope tube which provides an image which is right-way up and right-way round, and which permits the placing of attachments such as cameras in locations which do not impede the normal movements of the person using the microscope for observation. A first concave reflecting mirror (7) is arranged behind a tube lens (11) and serves to fold an initially vertical light path downwardly at an acute angle, while a second flat mirror (8) further folds it toward the eyepiece attachment location (21) An optical system (12) between the first and second mirrors again forms an intermediate image of the object (20) in the eyepiece cups (28a and 28b).
