Abstract
A viewing arrangement includes an objective (5) having a variable intersection distance and an intersection-distance dependent oblique illumination (7) which is separate from the objective (5). The oblique illumination (7) includes two illuminating beam paths (9, 11) for completely illuminating contoured objects without shadows. The illuminating beam paths (9, 11) are inclined toward each other ahead of the object (13, 16) to be viewed. The mutual inclination of the two illuminating beam paths (9, 11) is dependent upon the particular intersection distance of the objective (5).
