Abstract
A device for measuring imaging properties of an optical system including: a rigid holding device; and MTF measuring devices arranged at predefined positions of the holding device such that, by each of the MTF measuring devices, a modulation transfer function can be measured at respective different, predefinable, angular positions in the image field of the optical system; wherein the holding device includes at least a first holder and a second holder; the MTF measuring devices include a first group and a second group; the first holder holds the first group at first positions so that the first group are arranged on a first spherical shell; the second holder holds the second group at second positions so that the second group are arranged on a second spherical shell; and the first spherical shell and the second spherical shell have different radii and are arranged so as to be mutually concentric.
