Estimating the term…
The invention is directed to an optical arrangement for stereoscopic viewing of objects (8) which is outfitted with an imaging system and with at least one lens group (1) with a fixed focal length which is arranged between the imaging system and a viewed object (8) for changing the imaging scale. According to the invention, this is achieved in that an adjusting device is provided for changing the position of the lens group (1) in the direction of the optical axis and, accordingly, for changing the distance c between the lens group (1) and a reference edge (4) of the imaging system. This makes it possible to adjust different magnifications β′ by actuating the adjusting device or changing the distance c and, therefore, to generate virtual intermediate images of objects (8) 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.
Optical arrangement for stereoscopic viewing of objects which is outfitted with an imaging system and with at least one lens group (1) with a fixed focal length which is arranged between the imaging system and a viewed object for changing the imaging scale, wherein the lens group (1) and its position relative to the imaging system are designed for generating an intermediate image, and an adjusting device is provided for changing the position of the lens group (1) in the direction of the optical axis and, accordingly, for changing the distance c between the imaging system and the lens group (1), so that the imaging scale is variable in ranges greater than “zero”.
Optical arrangement according to one of the preceding claims, constructed as a stereomicroscope, wherein the lens group (1), including the adjusting device for changing distance c, is adapted to the base body of the stereomicroscope.
