A device for adjusting the back foci of an objective and a camera to one another has a housing by which a graphic pattern and an optics are mounted at a predetermined distance F' from each other. The temperature compensation for the distance F&#x2032; is constant to &#xb1;2 mm for a temperature change of Delta 20&#xb0; Celsius. The device also includes an apparatus for matching the back foci of an objective and a camera to each other, in which a housing has a fastening mechanism for fastening an object-side end of the objective and a graphic pattern is arranged in the housing on the end of the device opposite the fastening mechanism.
