ABSTRACT:
An optical arrangement for stereoscopic viewing of objects which is outfitted with an imaging system and with at least one lens group with a fixed focal length which is arranged between the imaging system and a viewed object for changing the imaging scale. This is achieved in that an adjusting device is provided for changing the position of the lens group in the direction of the optical axis and, accordingly, for changing the distance c between the lens group and a reference edge of the imaging system. This makes it possible to adjust different magnification β′ by actuating the adjusting device or changing the distance c and, therefore, to generate virtual intermediate images of objects located at various distances within a working range in the imaging plane of the stationary system. Accordingly, very advantageous applications are possible in restoration work, in dental engineering, and so on, in which the enhanced use value achieved by the invention is desired.
