ABSTRACT:
The invention concerns a stereomicroscope (1) for magnifying an object (T), having at least one zoom (22) through which, in the operating state, an object beam (K1) emitted from the object (T) is directed, the stereomicroscope (1) comprising a first deflection device (P4), arranged physically behind (after) the zoom (22) in the light path, for deflecting the light beam directed through the zoom (22) into a direction (A3) that deviates by less than 45° from the direction opposite to the object beam (K1). The light beam (A1) directed through the zoom (22) is advantageously deflected substantially into the direction opposite to the object beam (K1).
