Abstract
The invention is directed to a viewing arrangement (1) having a viewing optic (3) for viewing an object (5) along a viewing beam path. The viewing arrangement (1) also has an illuminating apparatus (9) for illuminating the object (5) along an illuminating beam path running segment-wise transversely to the viewing beam path. A beam-shaping illuminating element (15) is mounted in the segment of the illuminating beam path running transversely to the viewing beam path. The illuminating element (15) is asymmetrical relative to the illuminating beam path.
