摘要：The invention relates to an optical arrangement for the stereoscopic viewing ofobjects (8). The arrangement is provided with an imaging system and at least one lensgroup (1) of fixed focal length for altering the image scale, located between the imagingsystem and an object (8) being viewed. According to the invention, a regulating device isprovided for altering the position of the lens group (1) in the direction of the optical axisand hereby altering the distance (c) between the lens group (1) and a reference edge (4)of the imaging system. The actuation of the regulating device or more specifically, thealteration of the distance (c) hereby enables different enlargements β' to be set, in turnenabling the production of virtual intermediate images of objects (8) which are located atdifferent distances within a working field; in the image plane of the stationary imagingsystem. The invention could therefore be applied very advantageously to restorationwork in dental technology and other fields in which the service value provided by theinvention is desirable.
