Abstract
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′ is constant to ±2 mm for a temperature change of Delta 20° 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. The invention also includes a method for equalizing the back foci of an objective and camera using specific steps.
