Endoscope with two optical beam paths with switchable mirror surfaces

An endoscope (1) comprising two optical beam paths (3, 4) adapted for stereoscopic viewing, an associated optical element (9, 10, 11, 12) for each of the beam paths made of an optically transmissive material (14) that guides each of the beam paths (3, 4) in a section to an interface (15, 16, 17, 18, 19, 20) of the optically transmissive material (14) at a reflective point of incidence (21, 22, 23, 24, 25, 26) from an inside, each of the associated optical elements having one associated switchable mirror surface (27, 28, 33, 34, 35, 36) at the points of incidence (21, 22, 23, 24, 25, 26) of the beam paths (3, 4) with which a reflection behavior is variable at the respective point of incidence (21, 22, 23, 24, 25, 26), wherein the switchable mirror surfaces each have a switching element that is switchable between a first switching position, in which the switching element is arranged areally on the interface (15, 16, 17, 18, 19, 20) at the point of incidence (21,22,23,24,25,26), and a second switching position, in which the switching element (29,30) is spaced apart from the interface (15, 16, 17, 18, 19, 20), the switching elements are integrally or indirectly physically connected to one another, so that a mechanical alternation between first and second ones of the switching positions of the switching element on a first of the switchable mirror surfaces (27) is effected at a same time with a reversed change between the two switching positions of the switching element on a second of the switchable mirror surfaces (28).
